MINING PROCESS. After the coal mining permit is issued the first thing the mining company does is mark the permit boundaries and put up a mine identification sign. Then the company builds sediment ponds and berms. This is done to control all surface drainage, so that none leases the permit area without first passing through a sedimentation pond.

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.
Surface Coal Mining - Pennsylvania DEP
Surface mining activity includes the extraction of coal directly from the ground or from waste or stock piles, pits or banks. A permit is required to conduct surface mining activities. Permit area includes mining and support areas, facilities and roads. Permits are also required for exploration activities and processing plants.
Coal Exploration and Mining Geology
The overall process of coal exploration and mining involves six separate but interdependent and overlapping components: • Exploration: the identification and geological assessment of a new coal-bearing area; • Mine Design: the design and economic evaluation of the most appropriate mining operation to make use of the coal in that area;
Coal mining - Wikipedia
Processing coal After removing the coal from the ground, the miners may send it to a preparation plant near the mining site. The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials.
Basic Information about Surface Coal Mining in …
Once coal removal is complete, final regrading takes place and the area is revegetated. The operation is required to reclaim the mine to "AOC" or "approximate original contours" unless this requirement has been waived by the agency that has granted the Surface Mining Control and Reclamation Act of 1977 (SMCRA) permit for the operation.

Commonly used mining techniques to extract coal - ICSC
While open-pit mining involves extraction of coal from an open pit in the ground, strip mining includes stripping surface layers to reach coal deposits. Contour strip mining, area strip mining and auger mining are other techniques followed in surface mining of coal. In case of strip mining, coal seams are reached by removing the surface above them.
Coal mining - Wikipedia
Coal mining greatly increased during the industrial revolution and the following decades. The main mining areas were around Aachen, the Ruhr and Saar area, along with many smaller areas in other parts of Germany. These areas grew and were shaped by coal mining and coal processing, and this is still visible even after the end of the coal mining.
