Technical Field
[0001] The utility model relates to the technical field of ventilation devices, and more specifically to a safe ventilation and filtering device for coal mines. Background Art
[0002] Coal mines are areas where humans mine 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, it is generally chosen to dig tunnels underground to mine coal, which 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, which 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 ground, underground and related facilities. Coal mines are reasonable spaces dug by humans when digging geological layers rich in coal, usually including tunnels, shafts and mining faces, etc. Coal is the most important solid fuel and a type of combustible organic rock. It is formed by lush plants growing in a certain geological age, gradually accumulating into thick layers in a suitable geological environment, and buried in water or mud, and formed by natural coalification over a long geological period. Among the geological periods in the world, the Carboniferous, Permian, Jurassic and Tertiary strata produce the most coal, which are important coal-forming eras. The carbon content of coal is generally 46-97%, and it is brown to black with a dull to metallic luster. According to the degree of coalification, coal can be divided into four categories: peat, lignite, bituminous coal and anthracite.

Secondly, the gas causes serious harm to the workers, so it is necessary to exhaust the air underground. The existing exhaust equipment cannot filter when exhausting, and long-term use will easily cause pipeline blockage. Therefore, a new technical solution is needed to solve the problem.
