Surface Coal Mining and Reclamation. Surface coal mining involves disturbing overlying rock layers (overburden) to expose and extract coal reserves using the area mining method wherein the overburden above the uppermost coal seam and the innerburden between the lower coal seams are removed in parallel strips (pits) across the coalfield until the area is mined.
Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. Insitu mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground.
The Surface Mining Unit reviews applications and approves surface mining land use plans, issues surface mining permits, conducts compliance evaluations of surface mining operations, reviews and approves bonding requirements for surface mining operations and ensures reclamation of completed mining operations.
