[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. Open-pit coal mines have open sites with good ventilation conditions, while underground coal mines are deep underground and cannot be ventilated. Therefore, ventilation devices are needed to ventilate the mine. The basic task of mine ventilation is to supply enough fresh air underground to meet the oxygen needs of personnel, dilute harmful gases and dust underground, ensure safe production, regulate the underground climate, and create a good working environment.

[0003] The authorization publication number "CN213450458U" records "a ventilation device with protective function used in coal mines, including a blowing device, a U-shaped protective baffle is set on the outer wall of the wind tube by using a buffer column, and the connecting column made of foam cotton and rubber inside the bottom tube cooperates with the protective baffle to block the impact of falling objects on the wind tube, and the elastic buffer of the connecting column made of foam cotton and rubber absorbs the impact force of falling objects, thereby protecting the wind tube, thereby achieving effective protection of the wind tube, and providing an installation groove and a card slot on the wall at the inlet end of the wind tube to cooperate with a limit block to provide a connecting pipe, and the outer frame of the activated carbon filter is pressed and fixed between the connecting pipe and the installation groove.
