[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground and open-pit mines. When the coal seam is far from the surface, the coal is usually mined by tunneling underground, which is an underground coal mine. When the coal seam is very close to the surface, the coal is usually mined directly by stripping the surface soil layer, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines encompass large areas above and below ground, as well as related facilities. Coal mines are the reasonable spaces excavated by humans when excavating coal-rich geological strata, and typically include tunnels, shafts, and mining faces.
