[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to extract coal, which is an underground coal mine. When the coal seam is very close to the surface, generally, the surface soil layer is directly stripped to excavate coal, which is an open-pit coal mine. Most coal mines in China belong to underground coal mines. The scope of a coal mine includes a large area above and below the ground and related facilities. A coal mine is a reasonable space dug by humans when excavating a coal-rich geological layer, usually including roadways, shafts, and working faces, etc. Coal is the most important solid fuel and a kind of combustible organic rock.
