11 Most Massive Mines in the World
From the worlds largest gold mine found on the top of a mountain to the largest diamond mine in the world here are the most massive mines in the world! Subscribe to American EYE! 5.. Asbestos Mine, Canada Also known as the Jeffrey Mine, it’s located in Asbestos, Quebec and it was in operation until 2012. It’s a whopping 2 kilometers wide and 370 meters deep! Check out this thing on google maps and you can tell how completely massive this thing is! It’s the by far the largest asbestos mine in the world. For a long period of time, people would use this mineral to put into their walls and keep their homes from catching on fire! But recently there’s been a link with asbestos and a disease called mesothelioma, which is a lung condition. This is a toxic substance that people should avoid, so obviously this large mine went out of business. The lake at the bottom might look like an inviting blue, but you can bet your bottom dollar, it’s highly toxic! The small town that grew with the thriving asbestos industry feels like they’ve kind of lost their identity once the mine was forced to close, but people do still live there. 4. Mcarthur River Uranium Mine In case you were wondering which mine produces the most uranium in the world, that would be of course the Mcarthur River uranium mine in Saskatchewan Canada. This huge deposit was found in 1988 and finally a mining operation took place in 1997, when it began producing what’s known as Yellowcake. It’s not the kind of yellow cake you’d eat with your grandparents. This stuff has a horrific odor and basically what it is, is concentrated uranium powder which can then be used for powering nuclear reactors. We imagine this powdery substance is quite difficult to get ahold of. There aren’t a ton of photos of this place but, it does produce about 13 percent of the global uranium production across the globe. 3. Diavik Diamond Mine In case you thought it was Africa who had all the massive diamond mines, think again! The Diavik Diamond mine, found in the the northwest territories of Canada is one of the largest producers of diamonds in the Northern hemisphere and this place is pretty crazy! They annually produce 7 million carats of diamonds each year and you better believe it’s not easy to get here. The Diavik mine is found north of the arctic circle and it’s definitely cold! This photo here shows the subarctic landscapes that surround the diamond mine. You thought getting to work in the morning was tough for you? Imagine trying to get to work here! Just recently in 2015, this diamond produced what was known as the Diavik Foxfire 187.7 which is one of the largest rough gem quality diamonds ever produced. 2. Siberian Diamond Mine Also known as the Mirny Mine, The USSR began searching for ways to make to make themselves a more economical stable and independent union. In 1955 the Soviets discovered large diamond deposits at this site in the far away lands of Siberia and many people got to work very quickly in order to help bring wealth to the union. After about 20 years of operations, they finally decided that At one point this mine produced 10 million carats of diamonds a year and reaches a max depth of 524 meters or around 1700 feet making it the 2nd largest excavated hole in the world. The mine is so deep, airspace is closed over the hole due to helicopter crashes caused from the downward flow of air. The construction of this in the frigid conditions of Siberia must have been grueling and downright cruel. Sources state that the machinery used at this mine had to be covered at night or it would freeze Are the diamonds worth freezing to death?! It’s unoperational today but Some claim that there’s still a bunch of diamonds in this mine and the whole thing could be worth about 12 Billion dollars. It’s possible that controlling this diamond is mine is crucial to controlling the price of diamonds across the world. Bingham Copper Mine The bingham copper mine located near Salt Lake City Utah is home to the biggest pit in the world and it’s been in operation since 1903. It’s about 2.5 miles wide and if it were a stadium, it would be able to fit an estimated 9.5 million people. It keeps getting bigger and bigger too! Diligent workers can move about 250,000 tons of rock each day and it’s even become a tourist attraction in recent years before a massive landslide took place. Some claim that this was the biggest non volcanic landslide to take place in North American modern history. This photo we see here shows you the aftermath of this massive landslide and Bingham Copper mine and it makes you wonder how safe some of the conditions at these mines truly are. The landslides were so massive, that they actually triggered a few small earthquakes! Experts estimated that 165 tons of earth slide down from the top of the mine all the way to the bottom.

Most Amazing Open-pit Mines in The World (diamonds, gold, silver, copper...) [igeoNews]
Contribute to the Project: http://igeo.tv/contribuye-al-proyecto/ The Bingham Canyon Mine, also known as the Kennecott Copper Mine, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, USA, in the Oquirrh Mountains. The mine is owned by Rio Tinto Group, an international mining and exploration company headquartered in the United Kingdom. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.6 miles (0.97 km) deep, 2.5 miles (4 km) wide, and covering 1,900 acres (770 ha). It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April of 2013 and a smaller slide in September of 2013. Udachnaya was discovered on June 15, 1955, just two days after the discovery of the diamond pipe Mir by Soviet geologist Vladimir Shchukin and his team. It is more than 600 metres (1,970 ft) deep, making it the third deepest open-pit mine in the world (after Bingham Canyon Mine and Chuquicamata). The nearby settlement of Udachny is named for the deposit. As of 2010, Udachnaya pipe is controlled by Russian diamond company Alrosa, which planned to halt open-pit mining in favor of underground mining in 2010. The mine has estimated reserves of 225.8 million carats of diamonds and an annual production capacity of 10.4 million carats Chuquicamata, or "Chuqui" as it is more familiarly known, is by excavated volume the biggest open pit copper mine in the world, located in the north of Chile, just outside of Calama, 215 km northeast of Antofagasta and 1,240 km north of the capital, Santiago. The mine is owned and operated by Codelco, a Chilean state enterprise, since the Chilean nationalization of copper in the late 1960s and early 1970s. Its depth of 850 metres (2,790 ft) makes it the second deepest open-pit mine in the world (after Bingham Canyon Mine in Utah, USA). The Diavik Diamond Mine is a diamond mine in the North Slave Region of the Northwest Territories, Canada, about 300 kilometres (190 mi) north of Yellowknife. It has become an important part of the regional economy, employing 700, grossing C$100 million in sales, and producing approximately 7.5 million carats (1,500 kg (3,300 lb)) of diamonds annually.[2] The area was surveyed in 1992 and construction began in 2001, with production commencing in January 2003. It is connected by an ice road and Diavik Airport with a 5,235 ft (1,596 m) gravel runway regularly accommodating Boeing 737 jet aircraft. The Grasberg Mine is the largest gold mine and the third largest copper mine in the world. It is located in the province of Papua in Indonesia near Puncak Jaya, the highest mountain in Papua, and it has 19,500 employees. It is majority owned through a subsidiary by Freeport-McMoRan, which owns 90.64% of PT Freeport Indonesia, the principal operating subsidiary in Indonesia, including 9.36% owned through its wholly owned subsidiary, PT Indocopper Investama. The Government of Indonesia owns the remaining 9.36% of PT Freeport Indonesia. FCX operates under an agreement with the Government of Indonesia, which allows Freeport to conduct exploration, mining and production activities in a 24,700-acre area (Block A). It also conducts exploration activities in an approximate 500,000-acre area (Block B). All of Freeport's proven and probable mineral reserves and current mining operations are located in Block A. The 2006 production was 610,800 tonnes of copper; 58,474,392 grams of gold; and 174,458,971 grams of silver.

Berkeley Pit Located in Butte, Montana, this copper mine is now filled with heavily acidic water. Opened in 1955, this mine was used to get copper out of the Earth. Ironically it closed on Earth day in 1982. In the 80’s Berkeley Pit was 1700 feet deep and 900 feet wide. Approximately 320 million tons of ore and over 700 million tons of waste rock were mined from the pit. 5. Mir Mine This is a diamond mine, and one of the largest excavations in history. This mine in Russia is the 2nd largest man made hole in the world. Located in outside of Mirny, a small town in Eastern Siberia, this place is 1,722 feet (525 meters) deep, and 3,900 feet (1.25 kilometers) across. 4. IceCube Neutrino Observatory There are many different ways to make holes in the Earth as you know, or will soon learn. But for the University of Wisconsin, they wanted to do a study of the Earth from a different perspective. They decided to go to Antarctica and drill a massive hole into the very ice caps of the Earth to see what's down there. Thus, the IceCube Neutrino Observatory was made. 3.

Something amazing is happening outside of the city limits of Shanghai, an old, abandoned pit mine is being brought back to life. On this episode we’ll take a look how this old pit mine is becoming a hotel. The Intercontinental Shimao quarry hotel is a hotel being built at the site of an old pit mine in the Songjiang District of Shanghai, China. This 5 star hotel will be built in an S shape along one wall of the abandoned pit mine at the base of the Tianmeshan Mountain. This 18 floor hotel will designate 2 of those floors being underwater in the partially flooded pit at the bottom. The lobby, meeting center, recreation facilities and dining are the only 2 floors that will be above ground. The hotel will have 370 rooms, as well as a 1000 person conference room, grand ballroom cafes and restaurants on the ground floor. It is expected to have a soft opening by the end of 2017 and rooms will cost an estimated $320 per night. Hanging gardens will cascade off the roofs giving the image of a green hillside growing down the face of the pit as well as a vertical glass atrium will run from the bottom to the ground level disguised as a waterfall. Not only is this a hotel but it will feature extreme sports activities like bungee jumping, rock climbing and sightseeing platform. A lake will be made by filling in part of the pit in front of the hotel for swimming and relaxing in the sun. Construction has been difficult on this project but expected considering this is the world’s lowest artificial altitude hotel. The biggest challenges have been designing the safety systems like fire safety, waterproof facilities, and earthquake precautions. After many delays the project has moved forward swiftly since 2014. Drones, 3d scanners, and wire-release robots have all been used in the preparation for this building, allowing engineers to detect uneven rock surfaces, make precise measurements and help with transport of construction materials and workers.

Story Of Asbestos 1922 US Bureau of Mines - Johns-Manville; How Asbestos Was Mined
Geology & Earth Sciences playlist: https://www.youtube.com/playlist?list=PL33B1A9216BB65F7A more at http://quickfound.net 'A detailed silent film account of the production and manufacture of this most useful material. Operations are carried on at the Johns-Manville Co. plant. "Magic fibers - yesterday a curiosity, today a necessity - developed by the skill and resources of a great organization."' Silent. Public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. http://creativecommons.org/licenses/by-sa/3.0/ https://en.wikipedia.org/wiki/Asbestos Asbestos is a set of six naturally occurring silicate minerals, which all have in common their eponymous asbestiform habit: long (roughly 1:20 aspect ratio), thin fibrous crystals, with each visible fiber composed of millions of microscopic "fibrils" that can be released by abrasion and other processes. They are commonly known by their colors, as blue asbestos, brown asbestos, white asbestos, and green asbestos. Asbestos mining existed more than 4,000 years ago, but large-scale mining began at the end of the 19th century, when manufacturers and builders began using asbestos for its desirable physical properties: sound absorption, average tensile strength, resistance to fire, heat, electricity, and affordability. It was used in such applications as electrical insulation for hotplate wiring and in building insulation. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. These desirable properties made asbestos very widely used. Asbestos use continued to grow through most of the 20th century until public knowledge (acting through courts and legislatures) of the health hazards of asbestos dust outlawed asbestos in mainstream construction and fireproofing in most countries. Prolonged inhalation of asbestos fibers can cause serious and fatal illnesses including lung cancer, mesothelioma, and asbestosis (a type of pneumoconiosis). Illness from asbestos exposure can be found in records dating back to Roman times. Concern in modern times began in the 20th Century and escalated during the 1920s and 1930s. By the 1980s and 1990s asbestos trade and use was heavily restricted, phased out, or banned outright in an increasing number of countries. The severity of asbestos-related diseases, the material's extremely widespread use in many areas of life, its continuing long-term use after harmful health effects were known or suspected, and the slow emergence of symptoms decades after exposure ceased made asbestos litigation the longest, most expensive mass tort in U.S. history and a much lesser legal issue in most other countries involved. Asbestos-related liability also remains an ongoing concern for many manufacturers, insurers, and reinsurers... https://en.wikipedia.org/wiki/Johns_Manville Johns Manville is an American corporation based in Denver, Colorado that manufactures insulation, roofing materials, and engineered products. For much of the 20th century, the then-titled Johns-Manville Corporation was the global leader in the manufacture of asbestos-containing products, including pipe insulation, asbestos shingles, asbestos roofing materials and asbestos cement pipe. Johns Manville stock was included in the Dow Jones Industrial Average from January 29, 1930 to August 27, 1982 when it was replaced by American Express. In 1981, Johns-Manville Corporation was renamed simply "Manville". In 1982, facing unprecedented liability for asbestos injury claims, Johns Manville voluntarily filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code...

Bizarre Discoveries in Mines
Here are 11 of the most unusual findings deep in the earth like ancient and time primate fossils or trapped toads alive in rocks!! Subscribe to Talltanic http://goo.gl/wgfvrr # 7 Toads found in Rock One strange phenomena that still doesn’t have an explanation are toads that find themselves entombed deep into stone and continue to live. For years quarriers and miners have discovered to their surprise, live toads inside of the rocks they crack open. In some cases the toads are found 5, 10, and even 20 feet deep inside of rock. In all cases, they have no visible way in or out and yet in all cases they are all still alive. This bizarre phenomena is often called “toad in the hole”. No one knows how these toads find themselves in the rock, or how they survive without any water, food, or air. # 6 Ghost Miners in Mponeng The world’s deepest gold mine called the Mponeng Mine located in South Africa runs so far into the ground with so many winding tunnels that it’s almost like a dark underground city. The expansive, dark, and hot mine is almost impossible to completely keep watch over so every once in awhile an illegal squatter will be discovered. Mponeng squatters are called “ghost miners” and will find empty caverns to make their home in, illegally mine gold to sell above ground, and will even meet with prostitutes in the mines. # 5 The Bold Travelers of Mponeng - Desulforudis audaxviator In the world’s deepest gold mine, a new species of bacterium was discovered called Desulforudis audaxviator. Audaxviator translates to “bold traveller” which refers to the fact that the bacteria was found 2 miles below the surface of the Earth and is the only organism in its ecosystem. The strange bacteria has evolved to live without sunshine or oxygen. Instead, it lives off of hydrogen and sulfide as food, which come from the breakdown of radioactive elements. Basically, it’s a nuclear waste eating bacteria. It’s the only one of its kind and have amazed scientists with its complete solitude underground. # 4 Giant Roach Fossil Found in Ohio Coal Mine Geologists were combing through an old coal mine in an area known for its plant fossils when they discovered an extremely rare fossil. It was a giant roach fossil - about 4 inches long and twice as big as most modern American roaches. The fossil is rare because it’s completely in tact, while most insect fossils are only partial imprints. Fossils in the cave also preserved some of the smallest cockroach fossils ever found and their color patterns. Inside the coal mine, even more rare insect fossils were found including a rare ancient arachnid and a 60 inch long and 12 inch wide centipede. The chemistry of this coal mine in Ohio somehow preserved these insects with extreme detail that is not seen anywhere else. # 3 Dead Body found in Ghost Town Mine Hobby adventurers had the scare of their life when they were exploring an abandoned ghost town called Whroo in Victoria, Australia. The two were in the ghost town’s abandoned mine when they found a dead body covered in plastic and shoved into a deeper hole inside. The victim was a 50 year old man in a Neil Young shirt and the perpetrators were later found to be a 26 year old man and 30 year old woman. The details on this case are scarce, but it has all the makings of a really good CSI episode. # 2 Four Square Miles of Carboniferous Forest Discovered The fossils of almost an entire forest from the Carboniferous period was uncovered in the ceiling of two adjacent coal mines in Illinois. This discovery is the largest single-period fossil discovery in recorded history. Archaeologists delved into the 250 feet deep mine to explore and record the fossils. There were upwards of 200 specimens of detailed shrubs, trees, flowers, and even insects. # 1 Tiny, Strange Primate Fossil In the Krabi coal mine of Thailand, archaeologists uncovered a new species of a teacup sized primate. They found mandibles that belong to the pea-sized primates called Krabia minuta. Krabia minuta were native to Asia and are the ancestors to all monkeys, apes, and humans. They were impressively able to make it to Africa despite being separated from a body of water at the time that was bigger than the Mediterrenean sea. This bizarre find is very important for archaeologists, because it indicates a period of extreme evolution of primates in the area and will continue to yield more discoveries in years to come.

A Man Discovered This Dinosaur Fossil In An Old Mine, And What He Found Would Stun Paleontologists
Please do not forget to visit the site http://scribol.com ►Robert Clark/National Geographic https://goo.gl/CU5LnK contact us at:[email protected] http://watchjojo.com ************************************************************** Amidst the strange industrial landscape of Canada’s Athabasca oil sands, Shawn Funk is hard at work. At the controls of his excavator, he digs down through ancient layers, hoping to reach the precious bitumen beneath. But when his bucket strikes something hard, he makes a find that’s actually far, far more valuable. On March 21, 2011, Funk was on duty at Millennium Mine, a facility near Fort McMurray in Alberta, Canada. Operated by Canadian energy company Suncor, the mine is one of several built to capitalize on the deposits in the Athabasca oil sands. Covering some 54,000 square miles around Fort McMurray, these sands contain bitumen – effectively, extra-heavy oil. The deposits are made of the remains of animals and plants that lived over 100 million years ago. Under steady heat and intense pressure, these remains have been converted into bitumen. But to Funk and his colleagues, the deposits of course bear little resemblance to the incredible creatures they once were. Anyhow, early in the afternoon of that day something spectacular would happen. After spending hours digging for bitumen, the bucket of Funk’s excavator struck something solid under the earth. Then, as he watched, a series of strangely colored objects fell out onto the ground below. Funk therefore grabbed his supervisor, Mike Gratton, and the pair began to investigate what he had found. Picking up one of the lumps, they turned it over to reveal a bizarre pattern. Set into the gray rock was a series of brown circles, arranged neatly in rows. Funk and Gratton had no idea what they were looking at, though. Were the shapes just peculiar pieces of fossilized wood – or could they be something else entirely? The pair quickly realized that they needed to get an expert in to take a look at their discovery, so they duly contacted the Royal Tyrrell Museum of Paleontology in Drumheller, Alberta. Opened in 1985, the museum is a hub of research in an area that has seen hundreds of dinosaur fossils discovered over the years. Soon, then, curator Donald Henderson and museum technician Darren Tanke were on a plane headed for Fort McMurray. And when they arrived, they realized that it wasn’t just a pile of strange rocks that Funk had stumbled upon. In fact, it would turn out to be one of the most fascinating dinosaur fossils that they had ever discovered. The process of removing the fossils from Millennium Mine was, though, a long and arduous one. For many hours, the teams from Suncor and the museum worked away until the rock was whittled down to a single 15,000-pound piece. Then they prepared to lift it out of the mine. However, disaster struck. The fossil was too fragile to bear its own weight, and it broke into several pieces in mid-air. So while Henderson and Tanke were desperate to get the dinosaur remains back to the museum, they also didn’t want to damage the amazing find further. Eventually, then, the broken sections were encased in plaster of Paris and transported to Drumheller, some 420 miles away – and fortunately without further incident. Finally safe at the museum, the discovery was handed over to Mark Mitchell, a fossil preparer. And over the next five years Mitchell would spend some 7,000 hours painstakingly preparing the fossil for it to take center stage in a new exhibition. As he worked, meanwhile, researchers were able to take a closer look at the fascinating find. ************************************************************** ►Image credits: Image: Robert Clark/National Geographic https://goo.gl/CU5LnK Image: Beautiful Destruction https://goo.gl/Bht1Em Image: TastyCakes https://goo.gl/pP7uYY Image: Howl Arts Collective https://goo.gl/EJAoGo Image: National Geographic https://goo.gl/N7W6LE Image: Yetiwriter https://goo.gl/RMHEUw Image: Regional Municipality of Wood Buffalo Image: Royal Tyrrell Museum via MailOnline Image: R Lull https://goo.gl/iQ7aZp mage: Instagram/royaltyrrell https://goo.gl/F5UYCY Image: Facebook/Priti Obhrai-Martin https://goo.gl/AJkA8y Image: Machairo https://goo.gl/xoj2nM ►web: http://watchjojo.com ► SUBSCRIBE US: https://goo.gl/Z4nZcg ► Follow Us On Google Plus: https://goo.gl/JYf9Rr ► Like us Our Facebook Page: https://goo.gl/C5Rv92 ► Follow On Twitter: https://goo.gl/PZ2U1R ►For more articles visit: http://scribol.com ►reference:https://goo.gl/hZYsSA #watchjojo

Mine Cristal, mining quartz crystals
www.minecristal.ca Stay informed about our new videos: subscribe to our YouTube channel "Mine Cristal". This mine is located in Bonsecours, Quebec, Canada. Photos and video clips shown here date from 1989 - 2012. The open-pit mine produces splendid quartz crystals with exceptional clarity. The largest single crystals measure 60 cm (24 inches) in length. Since mining began in 1989, 32 types, or morphologies of quartz crystals have been catalogued. Geological research into the origins of these crystals has revealed that they formed at this location some 300 million years ago under extreme conditions of heat and pressure. We harvest crystals in the mine only as needed, to supply our store with a sufficient quantity of quartz crystals. Exceptionally (for a mine), we harvest all the crystals by hand and without the use of dynamite. It is a privilege for us to participate in the discovery and extraction of these true gems of nature. The extraction process is done in a manner which respects both the environment and the crystals: we endeavor to keep the crystals whole and in a pristine state. In the museum and the store, our crystals are presented in an untouched, natural state. Amazingly, each crystal is an intricate work of art made by Nature; no two are alike and this makes them even more fascinating! Mine Cristal is considered by experts to be a “geological gem,” one of Canada’s great natural sites, due to it’s unique and abundant mineralogical deposits.

Mining for Emeralds in Brazil by GIA
http://gia.edu/gem-encyclopedia Mining for Emeralds in Brazil by GIA. Emerald gemstone has many special qualities. From Sao Paolo, Brazil, Sergio Martins discusses the emerald gemstone history, industry and how sourcing this precious stone is performed in Brazilian mines. He explains the different types of Brazilian mining systems that exist at different locations throughout the country. The Belmont mine has a large area and conducts open pit mining on a large scale. They have consistently produced this precious gemstone for 30 years. Sergio also discusses the Nova Era mine, different from the other emerald mines because it belongs to over 140 people. Located in the area of Garimpeiro, emerald mining in this region involves miners making shafts and looking for the vein that leads to a large concentration of emerald, a “pocket”. Mining can take up to few years before any emerald stones are discovered, but once found, they can produce up to 10 million dollars worth of emeralds in one pocket.

Giant green emerald found in Zambian mine - TomoNews
KAGEM, ZAMBIA — Gemfields, the world's largest producer of green stones, has discovered a giant, green emerald in Zambia. The emerald weighs more than 1.1 kilograms and was discovered in Kagem, the world's largest emerald mine located in Zambia. A statement released by Gemfields said that the emerald has "remarkable clarity and a perfectly balanced golden green hue." Emeralds in the Kagem mine were reportedly formed 450 million years ago due to a rare combination of in situ minerals and magma from the Earth's crust which then developed into emerald crystals. The gem is being called "Inkalamu" which means lion in the local Bemba language in Zambia. The uncut emerald was discovered in an open-pit mine on October 2 by a geologist and a veteran emerald miner. Several pieces are expected to be cut from the 5,655-carat emerald and will be auctioned in Singapore this month. Most of the emeralds in the world are mined from Zambia, Colombia and Brazil. As a result, emeralds are even more precious than diamonds due to their scarcity.

Drones, Mines and Data
Drone2GIS offers a safe, efficient and accurate alternative approach to the conventional surveying method employed in open cast mines, quarries and stock yards for data acquisition. Through the employment of Unmanned Aerial Systems, Drone2GIS delivers precise, high accuracy ortho-photos, digital terrain models and virtual realities. With these products, we can extract features and positions to produce the same products one would expect from a conventional survey without the safety risks of having boots on the ground. Data can be captured as and when needed without significant impact on the day to day operation of the site and at a fraction of the time it would otherwise take. Take stock of your inventory with accurate volume measurements, visualize your site without the stock piles, and get the data you need when you need it with minimal impact on production! Surveying in an opencast mine, quarry or a stock yard has challenges. Setting up terrestrial scanners and other survey devices in the traffic of heavy equipment either slows down production or poses serious safety risks to the survey crews. Other safety and health risks involve steep ledges, potential for rock/land slides, noise and dust. Conventional surveying takes time, involves more than one person and can be very expensive. In addition to the safety concerns, logistics can also become difficult as parts of the location may need to be shut down while the survey takes place. Our approach saves time and money while ensuring a safer operation without boots on the ground.

Most scenarios allow us to drive the truck right down to the wreckage and perform our recovery without taking up any more lane than a rotator would. Another simple reason is price. They are very expensive trucks that, once again aren't really needed here. With that being said, that doesn't mean we will never get one just not at the moment.

10 Largest Gold Producing Countries in the World 2018
10 Largest Gold Producing Countries in the World 2018 10. Uzbekistan – 90,000 Kilograms With the gold production of 90,000 kilograms per year, Uzbekistan ranks at number 10 of the list. This country is rich on minerals such as silver, molybdenum, uranium, copper and of course gold. But the only challenge they face is shipping since this country is doubly landlocked. The gold produced in the country is nationalized and is owned by the Metallurgial Combinant mine and Navoi Mining. The largest mine of country is the Muruntau Gold mine which is the biggest open-pit mine in the world. 9. Indonesia – 100,000 Kilograms If Uzbekistan has the open-pit mine, Indonesia has the largest gold mine in the world. Large quantities of mercury is released into the atmosphere every year and therefore making people very unhealthy. The production of gold has increased from 2015 till date and it is expected to rise more as there are many gold reserves in this country which produce tons of gold year around. 8. Mexico – 125,000 kilograms The production of gold has been pretty consistent for past many years when it suddenly dropped in the year 2016. But even then the country has made rapid progress and had discovered many mines in the past few years which is why Mexico is still standing in the list of top 10 countries of the world producing gold. 7. South Africa – 190,000 kilograms Per year production of gold in South Africa is about 190,000 kilograms. This country had been one of the leading countries in producing gold but now ranks on 7th position. The most interesting thing is that there is so much which is not yet exploited so there is a possibility for this country to move up the ladder. The discovery of gold in the year 1886 transformed this country from an agricultural country to the gold producing country. 6. Peru – 150,000 kilograms With 150,000 kilograms of gold production every year, Peru ranks in number 6. This country is making a significant wealth from Gold profits thought the impact of mining has surely put the environment of the The Peruvian Amazon has been one such area which suffered to most since the mining increased to a whopping 400% in the last 100 years. The Chucapaca mine of Cusco Region is the largest mine which produces gold and silver. 5. Canada – 110,000 Kilograms The beautiful landscapes and the land of precious metals Canada ranks on number 5. Ontario region of Canada is the place from where the majority of the gold comes. The Red lake gold mine is the important source of Gold mining in Ontario. Though Canada has made it to number 5 but it is quite surprising that there are not many gold mines in this country. 4. United States – 237,000 kilograms The fourth largest producer of gold in the world is United Stated with 237,000 kilograms of production per year. Most of the mines are in Montana and Nevada. The gold is also hoarded up in the reserves of the Federal Government. The increase of gold in the past few years have led them reopen the once-closed mines in Montana region. The larger mines for gold production are in Alaska and western part of US. 3. Russia – 200,000 Kilograms On the third spot, we have Russia. Interestingly 5000 tons of gold is still unexplored as it is in the colder regions of Siberia. Having said that, in the year 1998, the production of gold in this area took a major hit but it again got rose significantly in the year 2014 that it even surpassed the United States. Russia is also the largest buyer of gold as per the report from Forbes. As many as 8000 tons of gold is still lying in the reserves. 2. Australia – 270,000 kilograms Australia earns the number 2 slot as the miners are literally having a hard time mining the land down under. Majority of the gold comes from Perth, New South Wales, Tasmania and Queensland. Golden Mile is the largest open mine. 1. China– 355,000 kilograms After a lot of research and development, China has finally succeeded to double the production of Gold and took the first place in the list of top 10 countries producing maximum gold in the world. China’s high population is also known to be the highest consumer of gold. Most of the mines are located between the capital city Beijing and Shanghai in the Shandong Province. Almost one-fifth of the production is held under China’s National Gold Group. With so much of wealth and gold accumulated in the reserves it is expected that the gold prices might take a hike in the times to come. Track : Vanze - Forever (feat.

OCP RKP Bigining Stage
Open Cast Mining is where the coal seam is relatively close to the surface, thus it is cost effective to remove overlying rocks to access the coal. The coal is then extracted. Open cast mining often has higher tonnage, and the overburden may also be of some economical value. Initially they are cheaper that deep coal mining,although just as expensive to extract the coal. Open cast (surface mining) affects habitats greatly (either by direct destruction, or indirectly such as blasting.)

The mine began production in 2015, and ramped up to an estimated production of 1.5 million carats in 2016. The mine is located just three kilometers from the Nyurbinskaya pipe, the principal asset within the Nakyn field. Botuobinskaya had an estimated 69.3 million carats of reserves as of January 1, 2015, and should continue to produce for more than 30 years. 9 - Mines - Venetia Where - south Africa E.st.reseves - 71.8. million carat It is currently the largest producing diamond mine in South Africa, and is located northwest of Kruger National Park near the border with Zimbabwe. In 2013, De Beers committed to invest up to $2 billion to expand the Venetia mine underground, with production to commence in 2022. The expansion plan could add considerably more reserves to the project than currently estimated. The company estimates that the expansion will extend the life of the mine until 2046. 8 - mines - Grib Where - Russia E.st.reseves - 91.5 million carat Grib is the only significant diamond mine in Russia that is not operated by ALROSA. It was discovered by oil and gas giant Lukoil during prospecting for natural gas near Verkhotina in the Arkhangelsk region of North-Western Russia. 2016 production is expected to be around 4.5 million carats. 7 - Mines - Argyle Where - Australia E.st.reseves - 93.1 million carat Although now nearing the end of its lifespan, the Argyle mine in Australia has been the largest producer of diamonds in history, and has produced more than 750 million carats of diamonds since 1982. After 30 years of mining the open pit, the mine transitioned to a fully underground operation in 2014, with an $800 million investment from Rio Tinto, the mine’s owner. 6 - mines - Mir(mirny) Where - Russia E.st.reseves - 97.4 million carat The Mir mine is an awe-inspiring site, and now ranks as the second-largest excavated hole on Earth. It is so big that flying over the mine is banned because of reports of airborne vehicles being sucked into the pit by the temperature and pressure deviations around the hole. It measures nearly 1.2 km in diameter, and more than 500 m in depth. The mine played a very important role in the development of the diamond industry and the eventual collapse of the De Beers cartel. 5 - mines - Udachny Where - Russia E.st.reseves - 108 million carat Udachny has been the most prolific mine in Russia’s history and could be considered the twin mine of Mir. It is 640m deep, and is so steep in places that it poses a safety risk for hauling trucks to fall off the side of the road. The open pit has been in operation since 1971, and has yielded $80 billion worth of diamonds from 340 million tonnes of ore. Like Mir, Udachny has transitioned into a fully underground mine, with an over $800 million development plan. Development is currently underway. 4 - mines - Vatican Where - Angola E.sr.reseves - 110 million carat Angola, accounting for 70% of the country’s production. It was first discovered in 1965 by artisanal diggers in the region. A mine was developed in 1994, and is owned and operated by Sociedade Mineira de Catoca, a joint venture which includes the state-run mining company ENDIAMA, and Russia-based diamond producer ALROSA, amongst others. The mine began production in 1997. 3 - mines - Jubilee Where - Russia E.st.reseves- 125.4 million carat Jubilee was the largest diamond mine in the world for many years, but it dropped to fourth spot due to high production rates at other mines over the past several years. The mine’s 2015 production was estimated at 9 million carats. However, with the addition of unproven underground reserves. 2 - mines - Jwaneng Where - Botswana E.st.reseves - 149.1 million carat Not surprisingly, the highest producing diamond mine in the world by value is also one of the largest. The Jwaneng mine is located 160 kilometers southwest of Gaborone in the south of Botswana. 1 - mines - Orapa Where - Botswana E.st.reseves - 151.4 million carat The mine in Botswana is located about 500km northwest of the capital city of Gaborone in central Botswana. Orapa, meaning ‘resting place of lions’, was discovered in the 1960s, shortly after Botswana gained independence from Britain. It began production in 1971, and has been one of the highest-producing mines in the world, ever since hitting a peak production of 17.3 million carats in 2006.
Mirny Mine - World's Biggest Diamond Mine, Russia
Mirny mine is a former open pit diamond mine located in Mirny, Eastern Siberia, Russia. This mine is 525 meters deep which made it 4th Deepest mine in the world with a diameter of 1,200 meter and is the second largest excavated hole in the world, after Bingham Canyon Mine. Now this Diamond mine is inactive, while it was operational it was taking two hours for trucks to drive from the top to the bottom of the mine. The diamond-bearing deposit was discovered on June 13, 1955 by Soviet geologists Yuri Khabardin, Ekaterina Elagina and Viktor Avdeenko during the large Amakinsky Expedition in Yakut ASSR. They found traces of volcanic rock kimberlite which are usually associated with diamonds. This finding was the first success in the search for kimberlite in Russia, after numerous failed expeditions of the 1940s and 1950s. For this discovery, in 1957 Khabardin was given the Lenin Prize, which was one of the highest awards in the Soviet Union. The development of the mine had started in 1957 in extremely harsh climate conditions. Seven months of winter per year froze the ground, which made it hard to mine in the winter, but turned into sludge in summer. Buildings had to be raised on piles, so that they would not sink in summer, and the main processing plant had to be built on a better ground found 20 km away from the mine. The winter temperatures were so low that car tires and steel would shatter and oil would freeze. During the winter, the workers used jet engines to thaw and dig out the permafrost or blasted it with dynamite to get access to the underlying kimberlite. The entire mine had to be covered at night to prevent the machinery from freezing.

Gold has been used for coinage, jewelry and adornments throughout recorded history. Goldsmithery is one of the oldest trades that displayed man’s artistic creativity. It can be traced back to the time of the pharaohs of Egypt. Gold was first mined in Arabia approximately 3000 BC. A second period of activity was during the Islamic Abbasid period between 750 and 1258 AD. Saudi Arabia is the World's largest gold Producer country. Saudi Arabia economy depend its oil and gold production. Besides The Kaaba sharif also located in Mecca major city of Saudi Arabia. ALLAH IS THE MOST MARCEFULL & GRATEST. Allah give many natural sources for wealth in Saudi Arabia. There are many gold mine in Saudi Arabia. Extraction of gold started in the Kingdom during the era of King Abdulaziz, particularly between 1939 and 1954, at Mahd Al-Dhahab after the deposit was rediscovered in 1932. Ma'aden Gold and Base Metals Company (MGBM), a wholly owned subsidiary of Ma'aden, undertakes the development and operation of gold and base metals. Al-Duwaihi is the largest gold mine in Saudi Arabia, located at Al-Khurma province. The mine accounts for more than half of Saudi Arabia's gold productions. Saudi Arabia's mining company Ma'aden invested more than $400 million (1.5 billion riyals) in its construction, infrastructure and facilities. Another Mahd Al-Dhahab was the first gold mine in the modern Saudi Arabia. In 2007, Mahd Al-Dhahab mined and processed approximately 183,425 tons of ore at a grade of 11.1 grams per ton of gold from underground operations, resulting in gold production of approximately 58,256 ounces. The mine also processes reclaimed tailings and produces copper and zinc concentrates for third party toll smelting. Bulghah mine is located in the Al Madinah Province, about 65 kilometers south of the Sukhaybarat metallurgical processing plant. It comprises an open pit mine, which mines lower grade ore (less than 1.0 gram per tonne of gold) for processing at the Bulghah heap leach processing facility. Higher-grade ore of more than (1.0) gram per tonne of gold is transported for processing at Sukhaybarat.

Dispatch with Confidence: Integration of machine learning
Dispatch with Confidence: Integration of machine learning, Optimization and Simulation for Open Pit Mines Kosta Ristovski (Hitachi America Ltd.) Chetan Gupta (Hitachi America Ltd.) Kunihiko Harada (Hitachi America Ltd.) Hsiu-Khuern Tang (Hitachi America Ltd.) Open pit mining operations require utilization of extremely expensive equipment such as large trucks, shovels and loaders. To remain competitive, mining companies are under pressure to increase equipment utilization and reduce operational costs. The key to this in mining operations is to have sophisticated truck assignment strategies which will ensure that equipment is utilized efficiently with minimum operating cost. To address this problem, we have implemented truck assignment approach which integrates machine learning, linear/integer programming and simulation. Our truck assignment approach takes into consideration the number of trucks and their sizes, shovels and dump locations as well as stochastic activity times during the operations. Machine learning is used to predict probability distributions of equipment activity duration. We have validated of the approach using data collected from two open pit mines. Our experimental results shows that our approach offers increase of 10% in efficiency. Presented results demonstrate that machine learning can bring significant value to mining industry.

Biggest Diamond mines in the world | Things you should know about these Mines
Orapa diamond mine (Botswana) is the world's largest open pit diamond mine in the world by area. The mine currently produces approximately 11 million carats (2,200 kg) of diamonds. Orapa is mining at a depth of 250 metres and is expected to reach 450 metres by 2026. Argyle diamond mine (Australia) is the largest diamond producer in the world by volume. It is the only known significant source of pink and red diamonds and other naturally coloured diamonds, including champagne, cognac and rare blue diamonds. Mir or Mirny diamond mine (Russia) is the second-largest manmade hole in the world .The harsh, frozen Siberian landscape made working on the mine a difficult proposition at best. Jet engines were turned on the unyielding permafrost in order to melt it; when that failed, explosives were used. Venetia is the largest diamond producing mine in South Africa. The open pit reserves are estimated to be 32.8 million carats diamond and the underground diamond reserves are estimated at 70 million carats diamond. Jubilee diamond mine (Russia) has been in production since 1989 and has diamond reserves of more than 150 million carats. It’s among the world’s biggest diamond mines by area. The mine was estimated to contain more than 153 million carats of recoverable diamonds, including 51 million carats of probable underground reserves. Botuobinskaya diamond mine (Russia) is estimated to contain roughly 70 million carats. The Botuobinskaya mine will produce 1.5 million carats of diamonds annually for more than 40 years. Catoca diamond mine (Angola) is the fourth-largest kimberlite mine in the world. Kimberlite was discovered at Catoca between 1965 and 1975; production actually began at the mine in 1998. Grib is the only diamond mine in Russia that is not operated by ALROSA. It was discovered by oil and gas giant Lukoil during prospecting for natural gas near Verkhotina in the Arkhangelsk region of North-Western Russia. Jwaneng diamond mine (Botswana)is the richest diamond mine in the world by value of recovered diamonds. It is estimated to contain roughly 88 million carats of diamond reserves. Udachny diamond mine (Russia) is the world’s second largest diamond mine by reserve size. It is one of the deepest open pit mines in the world, produced 10 million carats of diamonds a year until 2011. The worlds biggest ever diamond was the Cullinan, discovered in South Africa in 1905 and weighing just under 3107 carats before it was cut. Diamonds were first discovered in India and then in Brazil If you heat a diamond to more than 763C it will vanish like magic, leaving absolutely nothing behind, not even dust. At those temperatures the diamond simple expires in a tiny puff of carbon dioxide. Diamonds are brought to the earth’s surface by volcanic activity. Most are found in rock called Kimberlite, which is where the famous Kimberley diamond mine gets its name. Diamonds take about a billion years to develop and are formed deep in the earth’s crust, at least 90 miles down.
