surface coal mining process

Coal mining - Wikipedia

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.
