Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal bed is far away from the ground surface, a tunnel is generally dug underground, which is a minery coal mine, and when the coal bed is very close to the ground surface, a surface soil layer is generally directly peeled to dig the coal, which is an opencut coal mine.
The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others. Most coal seams are far from the surface, so open pit mining cannot be used. Underground mining accounts for 60% of the world's coal production. In a mine pit, the roof-and-column method is typically used to advance through the coal seam, with the beams and columns being used to support the pit. There are four major underground mining methods: longwall mining, continuous mining, blast mining, shortwall mining.
