Inferno Village. When leaving a land of fiery coal pits is scarier than burning alive
More films about India: https://rtd.rt.com/tags/india/ Jharia in India is like a hellish scene from a demonic horror movie: perpetually wreathed in suffocating smoke from an underground fire that has been burning for 100 years. Jharia’s coal fields represent the country’s richest reserves but the people forced to live here remain steeped in poverty. For many, pilfering and selling small baskets full of coal from the quarry is the only opportunity to make a meagre living. Whole families, including little children, labour in dangerous and harmful conditions. Living here is very risky: the ever-spreading pit of fire frequently consumes whole houses and blasting regularly shakes the whole village, damaging buildings and throwing plumes of coal dust into the air. High levels of carbon monoxide cause severe respiratory complaints among residents. Despite the danger, most families daren’t relocate because coal provides their only means of income. Some residents have been moved out, though not voluntarily, they’ve been relocated to a specially built township. However, unemployment and an underdeveloped infrastructure makes them homesick and wish they had never left their burning homeland. Local activists are standing up for the rights of Jharia population, they believe the relocation is motivated not by concern for the people’s interests but to free up more land for the government owned mining company to exploit.

Underground Fires Spread In Indian Coal Town
CHAN: Jharia was the richest coal mining town in India. Now underground fires have turned it into a ghost town. Here's more on the story. STORY: Subterranean fires in the Indian coal mining town of Jharia has lead to a mass evacution, turning the once rich coal mining community into a ghost town. Local say that despite the extensive work done by scientists no concrete steps have been taken to douse the fire. The few remaining people in the town have been living under constant threat of eviction and are unhappy with the government's relocation efforts. [SHAJAHA BEGAM, LOCAL]: " We are very scared and living under constant threat. We want the government to take some steps to relocate us. Though there have been several assurances on relocation, nothing has been done so far from the government side." The government meanwhile is engaged in the process of relocating the people to save them from hazardous living conditions. [R.B. CHAKRABORTY, DEPUTY DIRECTO MINES SAFTEY]: "Several people have been already shifted, but generally local people are resisting the move. This is not surprising but we are trying to convince them so that they move." Schools and colleges have been shut down and relocated. The township has been reeling from the impact of subterranean fires since 1923.

India's Environment Destroyed By Dangerous 'Rat-Hole' Mining
Broken Landscape: In rural India, the demand for coal has drastically altered the environment and the lives of those who depend on it. Unregulated 'rat-hole' mining serves the economy, but endangers both landscape and livelihood. “This place was pure and clean before. We used the river for drinking and cooking.” One fisherman recalls with painful nostalgia his memories of the river the village used to enjoy. “Now the people do not touch it. They are repulsed by it.” This is the result of the thousands of small-hold mines in the northeast Indian state of Meghalaya. They have run with no restriction – until now. The National Green Tribunal recently shut down mining in the region at the expense of the local economy, leading to coal mine owners and workers staging protests. With coal in such high demand, India has been forced to chose between economy and environment.

Future of Coal
Despite major shifts in the industry and serious worries in coal communities, today coal still supplies nearly 40% of our electricity. According to the Bureau of Land Management, one out of every five homes and business in the US use electricity made from Wyoming coal. But what does the future look like for fossil fuels in a world where there is increasing pressure to keep them in the ground? For regions that have historically been dependent on jobs and revenue from coal and oil extraction, innovation is key. Ideas like clean coal, carbon sequestration, and carbon utilization are some of the potentially game-changing technologies aimed at saving an industry while reducing emissions.

Taking the Carbon Out of Coal
A company called SCS thinks it can use coal to generate electricity while cutting down 90% on carbon emissions — and still make a profit. The company's PurGen plant, which would be located on the site where an old Dow Chemical plant used to stand near the New Jersey Turnpike in Linden, NJ, would use a technology called carbon capture and storage, or CCS. Carbon dioxide coming from the coal would be captured and pumped in liquid form deep underground, where it would — presumably — stay. To continue using coal while achieving an 83% reduction in greenhouse gas emissions by 2050, as called for in proposed legislation being discussed in Congress, will require increasing amounts of CCS in the coming decades. The PurGen plant would not burn coal, but rather turn it into hydrogen through a process that generates a stream of pure CO2 as a by-product. The hydrogen would be burned to make electricity with very little air pollution — but only when the demand for electricity is high, and the plant can get a good price. At times when demand is low, the hydrogen would be diverted and converted on-site into the chemical urea, used to make fertilizer. The storage part of SCS's plan involves building a two-foot-diameter pipeline to carry liquefied CO2 from the plant, under the Arthur Kill — a waterway separating New Jersey from Staten Island — and 140 miles out to a point on the bottom of the Atlantic Ocean, where it would be injected and stored about 8,000 ft. beneath the sea floor in a suitable geological formation. Supporters say the plan is a perfect solution to several problems at once — how to use the nation's cheap, plentiful coal supply without adding heat-trapping CO2 to the air, how to provide clean electricity to a part of the country that has to import power, and how to spark a green energy industry that could help the US maintain economic leadership in a time when China and other nations are determined to wrest it away. But not everyone thinks the PurGen project is a good idea. For one thing, even if the plant makes electricity cleanly, the mining and transport of coal will still have environmental impacts. For another, some worry that sequestering CO2 underground hasn't been adequately tested yet. And other critics say the money for PurGen would be better spent on solar or wind energy or energy efficiency — challenging the very premise that finding a way to use coal without carbon emissions is needed.

Canary used for testing for carbon monoxide 1926 US Bureau of Mines
In the early part of the 20th century, miners in Great Britain and the United States took caged canaries into coalmines in order to provide warning of the presence of toxic gases including carbon monoxide and methane. Canaries would visibly show distress and sway on their perches in the presence low concentrations of carbon monoxide before toppling over. The concept of the "canary in the coal mine" giving warning of a human health hazard is based on several principles. First, canaries were found to be more sensitive than both humans and other animals such as mice to the toxic effects of carbon monoxide. Second, the birds were allowed to share the same air exposures as the humans. Third, the occurrence of carbon monoxide poisoning in a bird was quite recognizable to the miners, since sick birds would tend to fall off of their perches and appear visibly ill. An article appearing in a 1914 issue of the Journal of Industrial and Engineering Chemistry provides a simple description of the concept (Burrell G, Seibert F. Experiments with small animals and carbon monoxide. Jl Indust Eng Chem. 1914;6:241--244.): Birds and mice may be used to detect carbon monoxide, because they are much more sensitive to the poisonous action of the gas than are men. Experiments by the Bureau of Mines show that canaries should be used in preference to mice, sparrows, or pigeons, because canaries are more sensitive to the gas. Rabbits, chickens, guinea pigs, or dogs, although useful for exploration work in mines, should be used only when birds or mice are unobtainable, and then, cautiously, because of their greater resistance to carbon monoxide poisoning. . . . Breathing apparatus must be used where birds show signs of distress, and, for this reason, birds are of great value in enabling rescue parties to use breathing apparatus to best advantage. For more on the use of animals as sensitive indicators of environmental hazards, providing an early warning system for public health, read the 2011Public Health Report - Animal Sentinels for Environmental and Public Health (http://www.publichealthreports.org/issueopen.cfm?articleID=2645 ) by John S. Reif, DVM, MSc, at Colorado State University, Department of Environmental and Radiological Health Sciences. This is clipped from the 1926 film by the US Bureau of Mines titles, Oxygen Breathing Apparatus. The film shows the kinds of breathing apparatus used in mine rescues and explains their various parts. A mine rescue team explores a mine, testing for low oxygen content and carbon monoxide. The entire film is posted to my channel.

What is COAL SEAM FIRE? What does COAL SEAM FIRE mean? COAL SEAM FIRE meaning & explanation
What is COAL SEAM FIRE? What does COAL SEAM FIRE mean? COAL SEAM FIRE meaning - COAL SEAM FIRE definition - COAL SEAM FIRE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A coal seam fire or mine fire is the underground smouldering of a coal deposit, often in a coal mine. Such fires have economic, social and ecological impacts. They are often started by lightning, grass, or forest fires, and are particularly insidious because they continue to smoulder underground after surface fires have been extinguished, sometimes for many years, before flaring up and restarting forest and brush fires nearby. They propagate in a creeping fashion along mine shafts and cracks in geologic structures. Coal fires are a serious health and safety hazard, affecting the environment by releasing toxic fumes, reigniting grass, brush, or forest fires, and causing subsidence of surface infrastructure such as roads, pipelines, electric lines, bridge supports, buildings and homes. Whether started by humans or by natural causes, coal seam fires continue to burn for decades or even centuries until either the fuel source is exhausted, a permanent groundwater table is encountered, the depth of the burn becomes greater than the ground’s capacity to subside and vent, or humans intervene. Because they burn underground, coal seam fires are extremely difficult and costly to extinguish, and are unlikely to be suppressed by rainfall. There are strong similarities between coal fires and peat fires. Across the world, thousands of underground coal fires are burning at any given moment. The problem is most acute in industrializing, coal-rich nations such as China. Global coal fire emissions are estimated to cause 40 tons of mercury to enter the atmosphere annually, and to represent three percent of the world's annual CO2 emissions. Coal seam fires can be divided into near-surface fires, in which seams extend to the surface and the oxygen required for their ignition comes from the atmosphere, and fires in deep underground mines, where the oxygen comes from the ventilation. Mine fires may begin as a result of an industrial accident, generally involving a gas explosion. Historically, some mine fires were started when bootleg mining was stopped by authorities, usually by blowing the mine up. Many recent mine fires have started from people burning trash in a landfill that was in proximity to abandoned coal mines, including the much-publicized Centralia, Pennsylvania, fire, which has been burning since 1962. Of the hundreds of mine fires in the United States burning today, most are found in the state of Pennsylvania. Some fires along coal seams are natural occurrences. Some coals may self-ignite at temperatures as low as 40 °C (104 °F) for brown coal in the right conditions of moisture and grain size. The fire usually begins a few decimeters inside the coal at a depth in which the permeability of the coal allows the inflow of air but in which the ventilation does not remove the heat which is generated. Two basic factors determine whether spontaneous combustion occurs or not, the ambient temperature and the grain size: The higher the ambient temperature, the more quickly the oxidation reactions proceed. The grain size and structure determine its surface area. Kinetics will be limited by availability of reactant, which in this case is carbon exposed to oxygen. Wildfires (lightning-caused or others) can ignite the coal closer to the surface or entrance, and the smouldering fire can spread through the seam, creating subsidence that may open further seams to oxygen and spawn future wildfires when the fire breaks to the surface. Prehistoric clinker outcrops in the American West are the result of prehistoric coal fires that left a residue that resists erosion better than the matrix, leaving buttes and mesa. It is estimated that Australia's Burning Mountain, the oldest known coal fire, has burned for 6,000 years. Globally, thousands of inextinguishable mine fires are burning, especially in China where poverty, lack of government regulations and runaway development combine to create an environmental disaster. Modern strip mining exposes smoldering coal seams to the air, revitalizing the flames.

Remote village hopes small coal mines not closed as part of govt plans to create reserve
Residents of Tausa, a remote village in central Colombia, fear that authorities will close the small coal mines that have sustained them and their families for as long as anyone can remember. Miners in "La Flauta" said on Wednesday that their small-scale "artisan" mine will close if authorities declare the area a nature reserve in which mining is prohibited and there will be no hope for their future. Government officials have been saying that for the time being there are no plans to close Tausa's mines, and despite their worries, workers continue with the manual labour that has been passed down through generations. From early in the morning, miners at "La Flauta" hop into railway wagons and travel through a maze of tunnels before reaching the seam, where they begin to extract coal. Then they chip, drill and pick for hours the mine's interior walls in search for the mineral. The effort though, seems that it's not paying off at the moment. "Right now mining has become difficult because there are no exports. There are no carbon sales. Carbon is very cheap and there are 40 families, 40 people working and depending from this mine and we all have wives and children," said Sebastian Echeverria, 45, who has been the administrator of the mine for 11 years. Miners say they earn about 600,000 pesos (318 US dollars) every two weeks. "If there was a way to advance with my family, support my family with other (types of) jobs, then I would do it," said Armando Pinzon, a Tausa resident who has been working in the mines for eight years. The plan to declare the area a nature reserve is being reviewed by the Environment Ministry, and most likely will not go into effect in the coming future. But for Tausa's residents, that doesn't calm their fears of being left unemployed. The Juan Manuel Santos administration cut its coal production goal for 2013 to 94 (m) million tonnes from 98 (m) million due to strikes afflicting the sector this year. In 2012 the sector produced more than 89.2 (m) million tonnes.

Georgia: Coal and Carbon
Coal is the most abundant fossil fuel and the least expensive one used to generate electricity in the US. It's also the source of many local problems, including those caused by strip mining and mountaintop removal, as well as disposal of toxic coal ash. But the biggest threat of all may be to the entire planet: burning coal releases large amounts of carbon dioxide, or CO2 — and carbon dioxide is a major contributor to climate change. Scientists say if the world continues emitting carbon dioxide following current trends, the average global temperature could rise by 7 degrees Fahrenheit or more by the year 2100, and by 9 degrees or more in the U.S. The oceans, expanding as they warm and flooded with melt-water from glaciers and ice sheets on land, could rise between two and five feet. In Georgia, a state that gets 60 percent of its electricity from coal (the national average is 50 percent), residents are already worried about the effects on their state's economy and ecology. As the temperature rises, the Live Oak — the state tree — could find it hard to thrive. Coastal cities like Savannah, meanwhile, will be under increasing threat from the rising sea. Like others across the country, Georgians are connecting the dots between how they get their electricity and what the future holds for their lives. As a result, they're trying to figure out how to cut down on the CO2 emitted by burning coal. One answer might be to reduce the amount of coal used — but coal is abundant and inexpensive, and therefore hard to give up. Yet it's also possible to reduce the amount of CO2 that comes from a coal-fired power plant. That's the idea behind "clean coal" or, to use the more technical term, carbon capture and sequestration (CCS). CCS technology could capture as much as 90% of the carbon dioxide emitted from coal power plants and pipe it deep underground, into porous formations of rock and sand that can absorb the CO2 and prevent its escape to the atmosphere. CCS technology appears to be viable, but implementing it at large scales is still at least a decade away. It also will require billions of dollars in investment, and some states, like Georgia, are less geologically suitable for storing carbon dioxide than others. CCS will make electricity from coal more expensive. And some opponents worry about whether any underground location can truly contain the CO2. The wider debate about clean coal and CCS is being played out on television, through a multimillion-dollar advertising war. Opponents say coal is a "dirty rock" that can't be wiped clean with an advertising campaign. They insist that even if the CO2 problem is fixed, mining, ash disposal and combustion will keep coal from being truly clean. The other side emphasizes the fact that coal is inexpensive, that the U.S. has domestic reserves that could last two hundred years or more, and that using coal is a prime way to help the U.S. remain competitive with fast-growing economies like China and India — both of which are major coal users. Even if CCS ultimately proves to be successful on a wide scale, experts say that there are steps people can immediately pursue to get a head start on reducing carbon dioxide emissions. "Efficiency is the first fuel that we should be going to," says Stephen Smith, Executive Director for the Southern Alliance for Clean Energy. Others point out that reducing CO2 emissions to the degree needed to avoid major climate change will require not only efficiency improvements, but also a portfolio of options. CCS, they say, could be one such option. Toward that end, the federal government is currently directing some stimulus funding to help demonstrate CCS technologies. Meanwhile, Congress is debating legislation to regulate carbon-dioxide emissions. If such legislation is approved, that could ultimately provide the necessary incentive for coal-burning companies to invest billions of dollars in CCS — the amount needed to make CCS a reality.

A coal mine on fire since 20 years
A village in Jharkhand continues to be engulfed by noxious fumes coming from a coal mine fire as high as three floors nearby. Kujju-Collieries Mines in Ramgarh district of Jharkhand has been burning continuously for 20 years now, putting lives of nearly 4,500 residents in danger. “The fire has been burning since before 2000, but it was small. But when Central Coalfields Limited (CCL), a subsidiary of Coal India Limited, opened the mines the fire came in contact with air and has constantly been spreading” says Lakhan, who works at the coal mines. The residents of the village are constantly inhaling the smoke and toxic fumes such of carbon monoxide and sulphur dioxide that constantly emanates out of the earth. “Residents here complain of respiratory and skin problems, constant head aches and many other ailments. But where can we go?” Lakhan tells Video Volunteer correspondent Basanti Soren. People here are also concerned, as the coal fire slowly spreads beneath the ground, threatening to open the surface and collapse land the very land they live on. However, the residents, mostly marginalized community of workers, have no source of employment apart from coal mines and no place else to go. “You think anyone wants to die like this? But we are poor people with nowhere to go. The government tells us to move, but is not making any arrangements for us either,” says Kishore Singh, a resident there. He further claims that CCL has been taking half-hearted measures to control this ecological and human disaster. He says, “CCL wants to just do a patch up work and put an end to this problem. But unless they cut the chunk of coal the fire will continue spreading – across the highway, railways and our homes.” Coal contains many trace elements, such as arsenic and mercury, which are dangerous to the environment. Coal also has traces of radioactive elements such as uranium, thorium, and other naturally-occurring radioactive isotopes which if released into the environment may lead to radioactive contamination. Though in small percentage, if enough coal is burned these substances are released, paradoxically resulting in more radioactive waste than nuclear power. Jharkhand has been home to many of India’s largest coal mines, but unknown to many it is also home to one of the longest burning coal fire in the world. Jharia, a coal mine in Jharkhand has been on fire since a century. Help the residents of the Kujju Collieries escape the ecological and human disaster before it is too late. Call Mr. M.K. Mishra, the general manager of Kujju Colliary on +91 8987785011 and inform him about the coal mine fire which has been lit since 20 years.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Anthracite Anthracite... is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminous coal and lignite. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92.1% and 98%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, and high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. China accounts for the majority of global production; other producers are Russia, Ukraine, North Korea, Vietnam, the UK, Australia and the US. Total production in 2010 was 670 million tons... Other terms which refer to anthracite are black coal, hard coal, stone coal... blind coal... Kilkenny coal... crow coal... and black diamond. In the United States, anthracite coal history began in 1790 in Pottsville, Pennsylvania, with the discovery of coal made by the hunter Necho Allen in what is now known as the Coal Region. Legend has it that Allen fell asleep at the base of Broad Mountain and woke to the sight of a large fire because his campfire had ignited an outcropping of anthracite coal. By 1795, an anthracite-fired iron furnace had been built on the Schuylkill River. Anthracite was first experimentally burned as a residential heating fuel in the US on 11 February 1808, by Judge Jesse Fell in Wilkes-Barre, Pennsylvania, on an open grate in a fireplace. Anthracite differs from wood in that it needs a draft from the bottom, and Judge Fell proved with his grate design that it was a viable heating fuel. In spring 1808, John and Abijah Smith shipped the first commercially mined load of anthracite down the Susquehanna River from Plymouth, Pennsylvania, marking the birth of commercial anthracite mining in the United States. From that first mine, production rose to an all-time high of over 100 million tons in 1917... From the late 19th century until the 1950s, anthracite was the most popular fuel for heating homes and other buildings in the northern United States, until it was supplanted first by oil burning systems and more recently by natural gas systems... China today mines by far the largest share of global anthracite production, accounting for more than three-quarters of global output. Most Chinese production is of standard-grade anthracite, which is used in power generation. Increased demand in China has made that country into a net importer of the fuel, mostly from Vietnam, another major producer of anthracite for power generation, although increasing domestic consumption in Vietnam means that exports may be scaled back. Current U.S. anthracite production averages around 5 million tons per year. Of that, about 1.8 million tons were mined in the state of Pennsylvania...

How to create cleaner coal - Emma Bryce
View full lesson here: http://ed.ted.com/lessons/how-to-create-cleaner-coal-emma-bryce It takes a lot of fuel to heat our homes, preserve our food, and power our gadgets. And for 40 percent of the world, cheap, plentiful coal gets the job done. But coal also releases pollutants into the air, causing environmental damage like acid rain and serious health problems. Can we create a cleaner version of coal? Emma Bryce details the three ways we might strip coal of its foul forces. Lesson by Emma Bryce, animation by Artrake Studio.

How Burning Fossil Fuels Leads to Climate Change | Chemistry for All | FuseSchool
Learn the basics about climate change and how burning fossil fuels adds extra carbon dioxide to the atmosphere, and how this then leads to climate change. Fossil fuels, like oil, coal and natural gas, are the remains of living things from millions of years ago. They are mainly composed of carbon with varying amounts of hydrogen. When the petrol burns, it joins with oxygen to build up hydrogen oxide and carbon dioxide. Before the world became industrialised by burning fossil fuels the carbon dioxide concentration in the atmosphere was about 0.028% tiny compared with oxygen at 21% and nitrogen at 78%, but enough to keep us warm. Without this natural blanket of insulating gas the earth would be too cold to support life as we know it. But this carbon dioxide released when fossil fuels burn adds to the existing carbon dioxide levels which are now nearly 50% higher than pre-industrial times. Although we get a daily supply of heat from the sun, the earth normally loses this (at night and in the colder seasons) so the average temperature of the earth remains constant. But this status quo is starting to change: as humanity adds carbon dioxide into our atmosphere the extra layer isolates the heat and it cannot escape as easily. The earth cannot lose its greenhouse gases quickly – and we keep adding to them! By putting our planet in a sweat box, we are causing wide ranging consequences for our climate and life on the planet. Some people think that living things contribute to the enhanced greenhouse effect because they breathe out carbon dioxide – but this carbon has come from their food and that has come from plants which took the carbon from the atmosphere in what is called the carbon cycle. Even burning wood does not contribute to the enhanced greenhouse effect as long as the trees you cut down are replanted. However the carbon in fossil fuels has remained trapped underground for 100’s of millions of years so it is extra carbon that is being added to the natural cycle. We are also throwing away other gases into the atmosphere which help trap infra-red radiation, and so also enhance the natural greenhouse effect. They are methane, especially from rice paddy fields and from cows and nitrous oxide NON from car exhausts. This rise in temperature cause our climate to change because extra energy is trapped on earth – already causing glaciers and ice caps to melt. With more energy in the atmosphere weather becomes more extreme, so there are more floods, droughts, and storms. Not everywhere will get warmer, but the climate is changing all because we have been using fossil fuels at an ever increasing rate.

OSM expects its rulemaking to trim 7,000 coal mining jobs in 22 states
1/27/2011 - Peter Mail, a spokesman for the surface mining reclamation office, said the proposal's aim is "to better strike the balance between protecting the public and the environment while providing for viable coal mining." Mali said the document is the first working draft that was shared with state agencies, which are giving their comments on it. (More) http://www.npr.org/templates/story/story.php?storyId=133248892 1/26/2011 - The Office of Surface Mining Reclamation and Enforcement document says the agency's preferred rules would impose standards for water quality and restrictions on mining methods that would affect the quality or quantity of streams near coal mines. The office, a branch of the Interior Department, estimated that the protections would trim coal production to the point that an estimated 7,000 of the nation's 80,600 coal mining jobs would be lost. Production would decrease or stay flat in 22 states, but climb 15 percent in North Dakota, Wyoming and Montana. . . . West Virginia Department of Environmental Protection official Thomas Clarke told the Associated Press on Wednesday. "I've had OSM technical people who are concerned with stream impacts and outside contractors for OSM who are subcontractors on the EIS give me their opinion that the whole thing's a bunch of junk."

In the past 12 months the Office of Surface Mining has increased the number of oversight inspections to evaluate how each state is administering its regulatory program. This a clip from: http://www.youtube.com/watch?v=U6WSvVpdm-w ---- 12/27/2010 - http://www.register-herald.com/todaysfrontpage/x258589936/What-s-in-a-name-Mountaintop-removal-vs-mountaintop-development (Excerpt) "In my mind, mountaintop 'removal' implies the site is mined and then left barren, lifeless and flattened. This couldn't be further from the truth," said Chris Hamilton of the West Virginia Coal Association. He points to the mining permit requirement that forces miners to restore the mines to their approximate original contour or to configure the land for an "alternate use." Restoring the land occurs in about 90 percent to 95 percent of former surface mines, Hamilton said. "We rebuild the mountain peak, resculpting it to approximately as close as possible to the original premining topography of the land, then we reseed it with grasses and trees," Hamilton said. However, Vivian Stockman, an organizer for the Ohio Valley Environmental Coalition, told West Virginia Public Broadcasting that a flyover of the southern West Virginia coalfields suggests little development on former surface mine sites. "If they're hoping to, you know, create shopping malls on some of these, I don't know where they're going to get all the shoppers," she said. "All the communities around these areas have been driven away." She added that the notion that West Virginia needs more flat land is a myth. "Back in 2002 we had some volunteers create some maps for us," she said. "There were just massive amounts of land that are not, in any way, shape or form, developed." Researchers from the Natural Resources Defense Council found that about 1.2 million acres and about 500 mountains were flattened by surface mining in central Appalachia. An aerial imagery analysis by NRDC found that about 90 percent of mountaintop removal sites were not converted to economic uses. Only about 4 percent of West Virginia and Kentucky mountaintops had been redeveloped, NRDC found. --- 11/18/2010 - Salazar Commends OSM Initiatives to Improve Oversight of State Surface Coal Mining Programs - http://www.doi.gov/news/pressreleases/Salazar-Commends-OSM-Initiatives-to-Improve-Oversight-of-State-Surface-Coal-Mining-Programs.cfm --- In June 2009, the U.S. Department of the Interior (Interior Department) entered into a Memorandum of Understanding (MOU) with the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers to reduce the harmful environmental impacts of coal mining in six states in central Appalachia. Through the MOU, the three agencies intend to strengthen oversight and regulation and minimize the adverse environmental consequences of mountaintop removal mining.

San Francisco Pollution Liability: Coal Mining
Although the usage of coal for electricity has gone down in recent years, coal mining still remains a valuable industry in the energy sector. Despite rising concerns about global warming in the U.S., large coal companies maintain that coal-fired power can be environmentally sustainable, and beneficial to the energy practices of Americans. Still though, coal mining comes with risks; with the environmental impact of the coal industry affecting land use, waste management, water, and air pollution. Atmospheric pollution is not the only type of pollution that raises concern; coal burning produces many solid waste products annually. These products include fly ash, bottom ash, flue-gas desulfurization sludge that contains mercury, among other chemicals, and more. According to environmental advocates, such as the writers for DeSmogBlog.com, research has found that a typical-sized coal-burning electricity plant in the U.S. puts out approximately 3.7 million tons of carbon dioxide, 10,000 tons of sulfur dioxide, 10,200 tons of nitrogen oxide, and more, per year. These sources say that a standard 500 megawatt coal-fired electrical plant burns about 1,430,000 tons of coal, uses 2.2 billion gallons of water, and uses 146,000 tons of limestone each year as well. Needless to say, owning and operating a coal mining company or any other type of energy production company comes with inherent risks. At DiNicola Insurance Services, we understand these risks; which is why we offer a comprehensive San Francisco Pollution Liability Program for business in the energy sector, as well as other various industries.

🇮🇳 India's Coal Rush | 101 East
India is hungry for energy. Over 173 power plants, all of them coal-fired, will be built to power the nation's high-tech industries and booming cities. This is accelerating an ongoing “coal rush” which has put our dirtiest fossil fuel at the heart of India’s breakneck growth, and could soon make a single state, Andhra Pradesh, one of the world’s top 20 carbon emitters. But not everyone is convinced that this boom is a blessing. Physicist and businessman, Asoke Agarwal believes that India is heading for disaster: "It is time that we think of a more austere way of living. That was what India was famous for earlier. Today we have just aped the West. The West has gone at a speed at which they are destroying themselves, and we are following them. So it is high time that we realise that there is something drastically wrong with our economy." On 101 East, filmmaker Orlando de Guzman takes a dark journey through the coal belt of Jharkhand and West Bengal, to look at the winners and losers of this booming industry.

Eco-Rehabilitation of Biodiversity in Forest Destroyed by Gold Miners - TvAgro by Juan Gonzalo Angel
Twitter @juangangel The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Besides creating environmental damage, the contamination resulting from leakage of chemicals also affect the health of the local population. Mining companies in some countries are required to follow environmental and rehabilitation codes, ensuring the area mined is returned to close to its original state. Some mining methods may have significant environmental and public health effects. Nuss and Eckelman (2014) provide an overview of the life-cycle wide environmental impacts of metals production associated with 62 metals in year 2008. Erosion of exposed hillsides, mine dumps, tailings dams and resultant siltation of drainages, creeks and rivers can significantly impact the surrounding areas, a prime example being the giant Ok Tedi Mine in Papua New Guinea. In areas of wilderness mining may cause destruction and disturbance of ecosystems and habitats, and in areas of farming it may disturb or destroy productive grazing and croplands. In urbanised environments mining may produce noise pollution, dust pollution and visual pollution. The implantation of a mine is a major habitat modification, and smaller perturbations occurs on an larger scale than exploitation site, mine-waste residuals contamination of the environment for example. Adverse effects can be observed long after the end of the mine activity. Destruction or drastic modification of the original site and anthropogenic substances release can have majors impact on biodiversity in the area. Destruction of the habitat is the main component of biodiversity losses, but direct poisoning caused by mine extracted material, and indirect poisoning through food and water can also affects animals, vegetals and microorganisms. Habitat modification such as pH and temperature modification disturb communities in the area. Endemics species are especially sensitive, since they need really specific environmental conditions. Destruction or slight modification of their habitat put them at the risk of extinction. Habitats can be damaged when there is no enough terrestrial as well by non-chemicals products, such as large rocks from the mines that are discarded in the surrounding landscape with no concern for impacts on natural habitat. Concentration of heavy metals are known to decrease with distance from the mine, and effects on biodiveristy follow the same pattern. Impacts can vary a lot depending on mobility and bioavailability of the contaminant : less mobile molecules will stay inert in the environment while highly mobile molecules will easily move into another compartment or be taken up by organisms. For example, speciation of metals in sediments could modify their bioavailability, and thus their toxicity for aquatic organisms. Bioaccumulation plays an important role in polluted habitats : mining impacts on biodiversity should be, assuming that concentration levels are not high enough to directly kill exposed organisms, greater on the species on top of the food chain because of this phenomenon. Adverse mining effects on biodiversity depends on a great extend on the nature of the contaminant, the level of concentration at which it can be found in the environment, and on the nature of the ecosystem itself. Some species are really resistant to anthropogenic disturbances, while some other will completely disappear from the contaminated zone. Time alone does not seem to allow the habitat to recover completely from the contamination. Remediation takes time, and in most of the cases will not enable the recovery of the diversity present before the mining activity.

India is aggressively expanding construction of coal fired power plants to meet growing energy needs. Some 455 new plants now are in the pipeline. With air pollution already a leading health concern, medical experts say this expansion can have dire health consequences. Emissions from coal power plants were linked to 80,000-150,000 premature deaths in India between 2011 and 2012 alone and to a wide range of diseases from cancers, to respiratory and cardiovascular disorders.

Canary used for testing for carbon monoxide 1926 US Bureau of Mines
In the early part of the 20th century, miners in the United States took caged canaries into coal mines in order to provide warning of the presence of toxic gasses including carbon monoxide and methane. Canaries would visibly show distress and sway on their perches in the presence low concentrations of carbon monoxide before toppling over. The concept of the "canary in the coal mine" giving warning of a human health hazard is based on several principles. First, canaries were found to be more sensitive than both humans and other animals such as mice to the toxic effects of carbon monoxide. Second, the birds were allowed to share the same air exposures as the humans. Third, the occurrence of carbon monoxide poisoning in a bird was quite recognizable to the miners, since sick birds would tend to fall off of their perches and appear visibly ill. An article appearing in a 1914 issue of the Journal of Industrial and Engineering Chemistry provides a simple description of the concept (Burrell G, Seibert F. Experiments with small animals and carbon monoxide. Jl Indust Eng Chem. 1914;6:241--244.): Birds and mice may be used to detect carbon monoxide, because they are much more sensitive to the poisonous action of the gas than are men. Experiments by the Bureau of Mines show that canaries should be used in preference to mice, sparrows, or pigeons, because canaries are more sensitive to the gas. Rabbits, chickens, guinea pigs, or dogs, although useful for exploration work in mines, should be used only when birds or mice are unobtainable, and then, cautiously, because of their greater resistance to carbon monoxide poisoning. . . . Breathing apparatus must be used where birds show signs of distress, and, for this reason, birds are of great value in enabling rescue parties to use breathing apparatus to best advantage. For more on the use of animals as sensitive indicators of environmental hazards, providing an early warning system for public health, read the 2011Public Health Report - Animal Sentinels for Environmental and Public Health (http://www.publichealthreports.org/is... ) by John S. Reif, DVM, MSc, at Colorado State University, Department of Environmental and Radiological Health Sciences. This is clipped from the 1926 film by the US Bureau of Mines titles, Oxygen Breathing Apparatus. The film shows the kinds of breathing apparatus used in mine rescues and explains their various parts. A mine rescue team explores a mine, testing for low oxygen content and carbon monoxide. The entire film is posted to my channel. This US Bureau of Mines film and many others are available at the US National Archive in College Park, Maryland.

Coal Mine Fire in Australia Could Burn for Months - Fire Service
The Victorian fire service tells Australians that a fire in an open cast coal mine, that has blanketed the town of Morwell in acrid smoke, could take months to put out. Full Story: Residents of Morwell in the Australian state of Victoria have been warned a fire in an open cast coal mine could take months to extinguish, according to the local fire service. The fire, which police believe was started deliberately, has been burning for more than two weeks sending plumes of smoke over the town, 95miles east of Melbourne, and threatening a power station which is right beside it, media reports said. "A very difficult fire fight and obviously a very tense time for our firefighters to make sure that the Hazelwood Power Station wasn't impacted nor on fire," said Craig Lapsley, Commissioner of the Victoria Fire Service. TV pictures showed some residents in Morwell have taken to wearing face masks to protect themselves from the acrid smoke, which has high levels of carbon monoxide, according to the State's Chief Health Officer, Dr Rosemary Lester. "Our priority at the moment is to concentrate on the short term health effects that we know that the smoke can cause. We know that the fine particles in the smoke can get down into the lungs and that can cause short term health effects like exacerbation of asthma, worsening of heart or other lung conditions and we know that the people who are most vulnerable to these effects are people with pre-existing heart and lung conditions, children, the elderly, smokers and pregnant women," Dr Lester said. The fire service is warning residents that forecasts of warm weather next week could hamper efforts to bring the blaze under control, local media reported.

But many climate-change alarmists seem to claim that all climate change is worse than expected. This ignores that much of the data is actually more encouraging than expected. Yes, Arctic sea ice is melting faster than the models expected. But models also predicted that Antarctic sea ice would decrease, yet Antarctic sea ice is increasing. Yes, sea levels are rising, but the rise is not accelerating—if anything, two recent papers, one by Chinese scientists published in January 2014, and the other by U.S. scientists published in May 2013, have shown a small decline in the rate of sea-level increase. We are often being told that we’re seeing more and more droughts, but a study published in March 2014 in the journal Nature actually shows a decrease in the world’s surface that has been afflicted by droughts since 1982. Facts like these are important because a one-sided focus on worst-case stories is a poor foundation for sound policies. Hurricanes are likewise used as an example of things getting worse. But look at the U.S., where we have the best statistics: if we adjust for population and wealth, hurricane damage during the period of 1900-2013 actually decreased slightly. At the U.N. climate conference in Lima, Peru in December 2014 attendees were told that their countries should cut carbon emissions to avoid future damage from storms like Typhoon Hagupit, which hit the Philippines during the conference, killing at least 21 people and forcing more than a million into shelters. Yet the trend for strong typhoons around the Philippines have actually declined since 1950, according to a study published in 2012 by the Journal of Climate. Again, we’re told that all things are getting worse, but the facts don’t support this. This does not mean that global warming is not real, or a problem, but the one-sided story of alarmism makes us lose focus. If we want to help the world’s poor, who are the most threatened by natural disasters, it’s less about cutting carbon emissions than it is about pulling them out of poverty. The best way to see this is to look at the world’s deaths from natural disasters over time. In the Oxford University database for death rates from floods, extreme temperatures, droughts, and storms, the average in the first part of last century, was more than 130 dead every year per million people. Since then, the death rates have dropped 97 percent to a new low in the 2010s of less than 4 per million. The dramatic decline is mostly due to economic developments that help nations withstand catastrophes. If you’re rich like Florida, a major hurricane might cause plenty of damage to expensive buildings, but it kills few people and causes only a temporary dent in economic output. If a similar hurricane hits a poorer country like the Philippines or Guatemala, it kills many more people and can devastate the economy. So let’s be clear. Climate change is not “worse than we thought.” That doesn’t mean it’s not a reality or not a problem. It is. But the narrative that the world’s climate is changing from bad to worse is unhelpful alarmism that prevents us from focusing on smart solutions.

Coal Seam Gas - The Fight For Our Lives - Spread Virally
Coal seam gas mining (CSG) is developing rapidly in New South Wales and Queensland and is commencing in other states. The legal and administrative protections are inadequate to ensure that public health is not harmed and that environmental damage does not leave a legacy for generations. The public health responsibilities of state and federal governments are to prevent harm by careful scientific assessment of possible hazards, their risks and methods of prevention. Therefore they deal particularly with clean air, clean water and uncontaminated food. Industry and state governments have frequently reassured the public that there are no dangers from CSG to water supplies and to their health. But what is their evidence? Overseas health concerns are emerging. A ban on shale gas mining in France and moratoriums in parts of the USA and South Africa are recent developments. The United States Environmental Protection Authority has begun a comprehensive study to investigate the potential adverse impacts that hydraulic fracturing may have on water quality and public health. There are differences between shale gas mining -- the predominant process overseas, particularly in the US -- and coal seam gas mining in Australia, in the depth of drilling and the volume of water brought to the surface, but there are health impacts common to both: the potential for contamination of water for drinking and agricultural use and for air pollution around wells. Hydraulic fracturing (fracking), often used in the mining process, involves the pressurised injection of a large volume of water, as well as chemical additives, into rock. The large volume of saline water returning to the surface contains injected contaminants and those leached from rocks and sediments. Nearby aquifers, ground water, soil and air may be contaminated. Some chemicals used in mining or leached from underground into water have the potential to harm human health given sufficient dose and duration of exposure, and this potential harm includes increased risks of cancer and other serious long-term outcomes. In a recent submission to the Senate Inquiry into Management of the Murray Darling Basin and the impact of CSG mining operations, Doctors for the Environment Australia has highlighted these concerns, recommending application of the precautionary principle, putting in place protections until sufficient research can be undertaken to adequately document health risks. Food quality and security is essential for good health. Agriculture, already under threat from more severe and prolonged drought conditions associated with climate change, will be further compromised by the CSG industry. As the industry expands, the vast quantities of water diverted from agricultural use to CSG operations and the loss of productive cropland may well diminish Australia's ability to feed itself and the world. Water and air pollution, water shortages, permanent degradation of productive agricultural land and loss of livelihood and landscape, all have mental health consequences for communities living in a gas field. The CSG process can divide previously close-knit rural communities, increasing tension and disharmony, impact on local economies, and threaten other industries such as tourism. But climate change is also an important health issue, and the carbon footprint of CSG over coal is said to be lower. Does this override other considerations? Not at all. Proper monitoring of fugitive emissions is needed to enable accurate comparisons with coal. The International Energy Agency has warned that there is a danger that over reliance on CSG will delay the vital transition to renewable energy. What needs to be done to protect human health? In any new development, health should be an integral part of the assessment process. State Departments of Health should have had a major role on the safety of a CSG development via a health risk assessment process. This is not currently happening in each state, and logically there should be one best practice national process. Adequate information is needed to support risk assessment and health protection and this is largely lacking. Greater transparency of industry practices and improved monitoring would start to fill this gap. There is a strong case for an independent, national Health Impact Assessment process, providing a uniform regulatory framework for the industry in all states and territories. While these protections are being developed, the precautionary principle should be exercised to recognise potential harms and err on the side of caution with any new CSG development. Human health relies on the maintenance of a healthy environment, clean drinking water, secure food production, the cohesion of community and family life. The new gold rush represented by coal seam mining should not be allowed to endanger these basic health needs of Australians.

The Role of Coal in a New Energy Age
The Role of Coal in a New Energy Age - Select Committee on Energy Independence and Global Warming - 2010-04-14 - For the first time in recent memory, the CEOs of America's top two coal mining companies, and a leading international company, came to Capitol Hill to answer questions on their positions on climate change, clean energy policy, and the challenges that face their industry. "Just as our national energy policy is at a crossroads, so, too, is the coal industry," said Rep. Edward J. Markey, who chairs the Select Committee on Energy Independence and Global Warming, the committee that hosted the CEOs. "Whether it's climate science, the viability of 'clean coal,' or safety concerns, I believe Congress requires answers from the coal industry on their ability to be a part of our clean energy future." As Congress continues to push for a comprehensive clean energy and climate bill, questions remain regarding the coal industry's position on the essential science of climate change and their potential to provide cleaner, lower-carbon fuel in the decades to come. The House-passed Waxman-Markey bill offered a pathway for coal to transition to carbon capture and sequestration technologies. The coal mining industry has seen significant developments over the last two weeks. A mining accident in West Virginia has renewed questions about the safety of coal extraction, and the U.S. Environmental Protection Agency has offered new rules on the environmental and health impacts of mountaintop mining. TESTIMONY: Gregory Boyce, President and Chief Executive Officer, Peabody Energy Corporation; Steven F. Leer, Chairman and Chief Executive Officer, Arch Coal, Inc.; Preston Chiaro, Chief Executive for Energy and Minerals, Rio Tinto; Michael Carey, President, Ohio Coal Association.

MIKE DMITRICH, DOGM Statewide Oral History Project
Born into a family of miners and raised in a coal mining community, Mike's long involvement with the mining industry in Utah began as an underground miner, moved into the role of government affairs specialist for a variety of mining companies, and finally included several decades in the State Legislature. Mike discusses his government affairs role and his concern over the possible impacts federal rules could have on Utah's coal industry. He also talks about how he was able to influence state and federal rules from his chair in the legislature. Among the discussion points are MSHA rules, taxes on coal production, compliance with the Surface Mining Act and Environmental Protection Agency regulations, the marketability of Utah coal, and the establishment of the current Abandoned Mines Program within the Utah Division of Oil, Gas, and Mining. Interspersed throughout the interview are Mike's observations about growing up in coal-rich Carbon County, Utah.

Safety Excellence - Moolarben Coal Operations, Yancoal (Safety Light)
Moolarben Coal Operations (MCO) employees were engaged in a consultative process to discuss issues and potential solutions for collision incidents between heavy mobile equipment in operational areas. All crews developed ideas and solutions and the most appropriate was deemed to be a signal light on the roof of tracked heavy equipment in operating areas. This entailed the operator initiating radio contact to dozer operators who then acknowledges through the signal light to establish positive communication between the operating equipment. The solution was risk assessed and trialled under a controlled environment for a period of time. MCO employees were again engaged at the end of the trial period to assess the outcomes and highlight any deficiencies and concerns. There was only positive feedback from employees and the system was implemented on all tracked equipment with an acceptable cost per unit. Since the implementation of the safety light system there have been no further instances of collisions between heavy mobile equipment in MCO's operating areas

Abandoned mine near Stanford offers clues on CO2 sequestration
Stanford scientists are studying an abandoned mineral mine near the campus for clues on how to sequester atmospheric carbon dioxide underground. Kate Maher, assistant professor of geological and environmental sciences, is heading a research project at the Red Mountain magnesite mine about 70 miles east of the university. The abandoned mine contains some of the world's biggest veins of pure magnesite, a mineral made of magnesium and carbon dioxide. The Stanford team is looking for insights on converting carbon dioxide emissions from power plants into magnesite that is permanently locked underground. The goal of the research is to curb global warming by removing CO2 from the atmosphere. The work is supported by the Global Climate and Energy Project at Stanford.

The Carbon Conundrum in :60
It's been on the lips of the president, a concern of the new pontiff, and on the minds of millions: global warming. Lucy Hutyra has heard the call and is seeking answers in her own backyard. The assistant professor of earth and environment says nearly 70 percent of global carbon dioxide emissions come from cities, which cover only 3 percent of our planet's surface but are home to more than half of the world's population. Until recently, few scientists were studying urban areas as unique ecosystems. Hutyra and a team of researchers, however, have spent the past year dissecting the origin of Boston's carbon emissions, and have begun tracing how urban-generated carbon is stored and processed over time. "If we are going to have a prayer of actually reducing greenhouse gas emissions, meeting commitments, and creating international treaties," says Hutyra, "we need to know where carbon dioxide is coming from within cities. It's the canary in the coal mine, so to speak." Read the story on the Annual Report: http://www.bu.edu/ar

Earth Month 2009: Clean Coal
Environmentalism is a global priority. That's a fact no one is willing to contest. But within the sustainability arena, there is still plenty of room for debate on how to best achieve goals. In conjunction with Ohio University's designation of April as Earth Month, Sustainability Coordinator Sonia Marcus takes on faculty members from across the academic spectrum, addressing some of the most controversial issues facing the environment, both locally and globally. These debates showcase the wide diversity of opinions that coexist within the community of environmental advocates. In today's debate, Marcus and Associate Professor of Journalism Bernhard Debatin discuss the legitimacy of clean coal -- or methods used by coal producers and utilities to reduce coal's environmental impact. Debatin addresses this topic among many local environmental concerns in his recently created journalism course, "Localizing Environmental and Science Journalism." The course was triggered by Debatin's involvement in the Kanawha Environmental Education Project, a professional development series that aims to integrate concepts of environmental sustainability into Ohio University's curriculum. In addition to teaching environmental journalism, Debatin has devoted the past two years to researching the environmental and social impacts of coal mining in Athens County.
