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, which include large areas of the ground and underground and related facilities, are reasonable spaces excavated by humans when excavating coal-rich geological formations, typically including roadways, wells, and mining surfaces. Coal mine safety accidents are more, however, people have far insufficient attention to hurting people and damaging equipment in the rock burst accident, and no corresponding effective safety device exists. Rock burst, also known as rock burst, is a phenomenon in which elastic deformation potential energy accumulated in a rock mass is suddenly and violently released under certain conditions, causing the rock to burst and be ejected.
