[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. 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. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal is the main solid fuel and a type of combustible organic rock. According to the degree of coalification, it can be divided into four categories: peat, lignite, bituminous coal and anthracite.

The hydraulic support for coal mines is a kind of safety support equipment commonly used in the production process. At present, in the process of coal mining, the column lowering and frame moving operation of the hydraulic support will generate a lot of dust. The dust mainly comes from the direct contact between the hydraulic support and the top plate of the working face. From the structure of a single hydraulic support, the dust mainly enters the frame joints of the working face from the frame joints on both sides, polluting the working environment of the staff and reducing the efficiency of the staff in coal mining.
