Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. In the coal mining process, a large amount of dust is generated in working procedures of a mining surface, a transfer point, a conveyor belt, ore crushing, sieving and the like in a tunnel, and the dust not only causes pollution to the environment, but also seriously harms the health of operating personnel.

Among the prior art, the mode that leads to the filter board to filter and adsorb with the water that lead to more removes dust to the colliery, nevertheless because the filter media is easy to be blockked up by the dust, need regularly clear up, and the contact of air and water is not abundant, and it is relatively poor to lead to actual adsorption effect, is unfavorable for the use, therefore we have provided a colliery ventilation dust collector and have been used for solving above-mentioned problem.
