the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) than underground mines of similar capacity. Strip mining is one of the

What is the mining process? Mining is the process used to extract valuable resources from the Earth. It is done to acquire any resource that cannot be grown or fabricated through artificial means. More specifically, mining is used to extract non-renewable resources like fossil fuels, minerals and even water. How coal is extracted from coal mines?

This form of mining involves mining the coal seam in a checkerboard style, which leaves pillars of coal that support the roof. This, in turn, makes it faster to get to the coal access with low invest, when compared to longwall mining. In room-and-pillar mining, however, only 50% to 75% of the coal reserves are utilized.

What is the process of mining coal? Coal Mining and Processing. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted. Click to see full answer.

Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
