Description

Dust collector for coal mine

Technical Field

The utility model relates to an equipment for the colliery specifically is a dust collector for coal mine.

Background

The method is an area for mining coal resources in a coal-rich mining area by human beings, and is generally divided into a mineworker coal mine and an opencast coal mine. 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. Coal mines are reasonable spaces excavated by humans when excavating geological formations rich in coal and generally include roadways, wells, and mining surfaces, among others. Coal is the most predominant solid fuel, one of the flammable organic rocks. It is formed by that the flourishing plants grown in a certain geologic age are gradually piled up into a thick layer in a proper geologic environment, and are buried in the water bottom or silt, and then are subjected to the natural coalification action in a long geologic age. In the geologic periods of the world, most coal is produced in the stratums of the stone charm, the pilaster, the Jurassic and the third era, which is an important coal-forming era. The carbon content of the coal is generally 46-97%, and the coal is brown to black and has dull to metallic luster. According to the degree of coalification, coal can be classified into peat, lignite, bituminous coal and anthracite.

In the coal mining process, the coal mine air conditioner needs to work in the coal mine, the air quality in the coal mine is very poor, a large amount of dust is filled, health threats are brought to workers, meanwhile, the coal mine is easy to explode due to the fact that the air in the coal mine contains a large amount of gas, and the working safety of the coal mine is reduced.
