Description

Technical Field

[0001] The utility model relates to the technical field of coal mine screening, in particular to a coal mine screening device used in coal mine mining. Background Art

[0002] It is an area where humans mine coal resources in coal-rich mining areas, which is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. Most of my country's coal mines are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological layers rich in coal. They usually include tunnels, shafts, and mining faces, etc. Coal is the main solid fuel and a type of combustible organic rock. It is formed by 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 and sand. It is formed by natural coalification over a long geological period. After coal mining, it needs to be screened.
