When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. A coal mine is a reasonable space excavated by humans when digging geological strata rich in coal. It usually includes tunnels, shafts, and mining faces, etc. Coal is the main solid fuel and a type of combustible organic rock. It is composed of lush plants that grow in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried under water or in mud. It is formed by natural coalification over a long geological period. In the process of drilling and waterproofing, coal mines need to use anti-collapse hole protective pipes to protect the boreholes and reduce the collapse of the holes.
