Most of coal mines in China belong to underground coal mines. Coal mine range includes large areas of above-ground and below-ground and related facilities. Coal mines are reasonable spaces that humans excavate when mining coal-rich geologic formations, typically including roadways, shaft pits, face surfaces, etc., and roof pressure is generated at the top when the coal mine is being collected.
