rock, then dig out the coal. Th is is called surface mining. After the coal is mined, they put back the dirt and rock. Th ey plant trees and grass. Th e land can then be used again. Th is is called reclamation. If the coal is deep in the ground, tunnels called mine shafts are dug down to the coal. Machines dig the coal and carry it to the surface. The overall coal mining process consists of several sequential stages (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks (2) analysis and selection of a mining plan (3) securing the markets (4) developing the mine (5) extracting the coal (6) processing the coal if necessary and (7)

CDC Mining Feature Coal Mine Explosion Prevention

Dec 09, 2011 Underground coal mining produces finely divided coal dust that deposits throughout the mine and serves as a source of combustible material for coal dust explosions. Limestone powder, known as rock dust, is spread throughout the mine workings on a regular basis. This rock dust serves to inert the coal dust when applied in the proper proportion. Strip mining is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden) this activity is also referred to as overburden removal.It is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface and/or is mostly horizontal.
