in coal mining areas has become an urgent problem to be solved. In recent years, researches on ecological environmental management in coal mining areas have become a very popular project for scholars to deal with. In one branch, for a review of the literature on policies of ecological environmental management in coal mining areas, see [37].
Once coal removal is complete, final regrading takes place and the area is revegetated. The operation is required to reclaim the mine to quot;AOCquot; or quot;approximate original contoursquot; 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.

Burning coal emits large amounts of carbon dioxide into the atmosphere. Coal is composed almost entirely of carbon, so burning coal unleashes large amounts of carbon dioxide (CO 2) into the atmosphere. These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global warming. Subsurface coal mining is dangerous.

Coal, salt, uranium, phosphate and oil shale live in soft rock and there are two primary methods in softrock mining: longwall and room and pillar [source: Great Mining].Most coal is extracted using the roomandpillar approach described previously [source: United Mine Workers of America].However, longwall mining is exploding in popularity [source: Great Mining].
The handling as well as the processing tasks of this process has shaped the character of the coal handling plant. The use of dozers and mobile equipments are done for feeding purpose. The efficient and economical storage, movement and control of large tonnage coal handling installations, coal car unloading, storage, reclaim system depend on the
Coal Mining Process Diagram: The motors used for Coal Mining Process Diagram must be flame proof. They operate at high ambient temperatures. Sometimes the environment may be humid and the motors should have humid proof insulation. The motor must satisfy very stringent specifications. The motors used in Coal Mining Process Diagram can be classified into two groups.
