Background

Coal is the most predominant solid fuel, one of the flammable organic rocks. 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 seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit 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.

When the coal mine is mined underground, ventilation openings need to be arranged at the coal mining site, and the common coal mine ventilation openings cannot meet the requirement of coal mine ventilation in use due to simple structures.
