Coal mines are areas where human beings exploit coal resources in rich coal mining areas, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally chosen to dig tunnels underground for coal mining, which is an underground coal mine. When the coal seam is close to the surface, it is generally chosen to directly peel off the topsoil to dig coal. This is an open-pit coal mine. Most coal mines in China belong to underground coal mines.

The scope of coal mine includes a large area of ground, underground and related facilities. Coal mine is a reasonable space excavated by human beings when mining geological strata rich in coal, which usually includes roadway, adit, mining face and so on. Coal is the most important solid fuel and a combustible organic rock.

It is formed by lush plants growing in a certain geological age, gradually accumulating into thick layers in a suitable geological environment, buried in the bottom of the water or sediments, and formed by natural coalification in a long geological age. Among all geological periods in the world, Carboniferous, Permian, Jurassic and Tertiary strata produce the most coal, which is an important coal-forming era.
