Underground coal mine :- Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping point (limited by geology, ventilation, or economics), a supplementary version of room and pillar mining, termed second mining or retreat mining, is commonly started. Miners remove the coal in the pillars, thereby recovering as much coal from the coal seam as possible. A work area involved in pillar extraction is called a pillar section. Modern pillar sections use remote-controlled equipment, including large hydraulic mobile roof-supports, which can prevent cave-ins until the miners and their equipment have left a work area. The mobile roof supports are similar to a large dining-room table, but with hydraulic jacks for legs. After the large pillars of coal have been mined away, the mobile roof support's legs shorten and it is withdrawn to a safe area. The mine roof typically collapses once the mobile roof supports leave an area.

How is coal mined? Read Full Story: http://www.spoonfeeding.in/2013/02/how-is-coal-mined-what-is-surface.html Mining is the process of removing coal from the ground. There are two types of mining: underground mining and surface mining. When the coal seam is fewer than 125 feet under the surface, it is mined by surface mining. Coal that is deeper than 125 feet is removed from the ground by underground mining. Underground mining is used when the coal seam lies deep in the earth. In an underground mine only some of the coal is removed. The coal that remains helps support the mine roof. Underground mines look like a system of tunnels. The tunnels are used for traveling throughout the mine, moving coal from place to place and allowing air to circulate in the mine. The coal that is mined is put on conveyor belts. The conveyor belts take the coal to the surface. There are three types of underground mines: slope, drift, and shaft. When the coal seam is close to the surface but too deep to use surface mining, a slope mine can be built. In a slope mine a tunnel slants down from the surface to the coal seam. A drift mine is built when the coal seam lies in the side of a hill or mountain. Drift mines may also be built in a surface mine that has become too deep. There are many drift mines in the eastern United States. The most common type of mine in Illinois is the shaft mine. These mines may be 125 to 1,000 feet deep. A large hole, or shaft, is drilled down into the ground until it reaches the coal seam.

The goal of coal mining is to obtain coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United States, United Kingdom, and South Africa, a coal mine and its structures are a colliery. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyors, jacks and shearers. - H&T

Coal Curse, a film by Paranjoy Guha Thakurta, supported by Greenpeace, takes you on a journey to the land of dirty coal and the trials and tribulations of the people working in the coal mines. The documentary explores the political economy of coal in contemporary India with the situation in Singrauli as a case study. It highlights the scandal, popularly called Coalgate, and the consequences of coal mining in the Singrauli region in central India. It raises questions as to whether extraction of coal is the best answer to secure India's energy needs.

Caterpillar has extensive experience in the design of roof supports for specific mining conditions. Cat Longwall Top Coal Caving (LTCC) roof supports allow mining of seams seams thicker than 6 meters (20 feet). Following a conventional cut with a shearer to about 3 m (9.8 ft) the roof supports move forward and allow the caving of the top coal behind the roof supports a second conveyor mounted gob-side. This special LTCC method enables increased coal reserve recovery for only an incremental additional cost. This animation shows how it works.

Jharia lies at the heart of India's largest coal belt, within the north-east state of Jharkhand. The area produces almost all of the country's high-quality coking coal required in the production of steel as well as in thermo-electricity plants. Yet the vast open cast mines that stretch through these lands lie on top of underground fires that have been burning for over a century. Recent mining expansions have provoked these flames causing over 70 open fires to erupt along the earth's surface, spewing noxious gases and destroying the land. Those hardest hit are local villagers and workers in towns such as Jharia - forced to endure poisonous air, dangerous fires and unbearable heat. Envrionmental activists have highlighted how the state-run coal mining BCCL firm has deliberately exacerbated the open fires, so as to justify the eviction of locals due to safety risks, and thereby clear the areas of coal-rich land suited for their expansion. The nearby town of Dhanbad is particularly notorious for its 'coal mafia' - an informal name given to the corrupt mechanics behind India's coal trade - one mired by greed and exploitation. Earlier this year, Prime Minister Narendra Modi announced plans to double state-produced coal by 2020 in the hopes of meeting India's rapidly rising energy demands. Yet, in the setting of global climate change and emission responsibilities, coal remains one of the dirtiest forms of energy production. Set in the bleak and naturally striking scenery of Jharia, this story looks into the poverty-stricken, remote and forgotten lives of people at the mercy of corporations and governed by coal. This is the story of those buried beneath Indias billion dollar coal operations - the dirty end of a dirty business.

A coverage of Open-pit mining, open-cut mining or opencast mining at Junnar Deo in Madhya Pradesh. Open-pit mining, Open-cut mining or Opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. Open-pit mines are used when deposits of commercially useful minerals or rock are found near the surface; that is, where the overburden (surface material covering the valuable deposit) is relatively thin or the material of interest is structurally unsuitable for tunneling (as would be the case for sand, cinder, and gravel). For minerals that occur deep below the surface - where the overburden is thick or the mineral occurs as veins in hard rock - underground mining methods extract the valued material. Open-pit mines that produce building materials and dimension stone are commonly referred to as quarries. Open-pit mines are typically enlarged until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic. When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid wastes. However, some form of water control is usually required to keep the mine pit from becoming a lake, if the mine is situated in a climate of considerable precipitation or if any layers of the pit forming the mine border productive aquifers.
