Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal mine tunneling, especially relates to a ventilation equipment for coal mine tunneling. BACKGROUND

[0002] Coal mine is the area where human beings exploit coal resources in the mining area rich in coal, which is generally divided into underground coal mine and open coal mine. When the coal seam is far from the ground surface, the general choice is to excavate the roadway underground to mine coal, which is the underground coal mine. When the distance between the coal seam and the ground surface is very close, the general choice is to directly strip the surface soil layer to excavate coal, which is the open coal mine. Most of the coal mines in China belong to underground coal mines. The scope of coal mine includes a very large area of aboveground and underground as well as related facilities. Coal mine is the reasonable space excavated by human beings when excavating the geological layer rich in coal. It usually includes roadway, shaft and mining face, etc. Coal is the most important solid fuel and a kind of combustible organic rock. It is formed by the long-term natural coalification of the thick layer of lush plants grown in the geological period and buried in the water bottom or silt. In the world, the most coal is produced in the geological periods of Carboniferous, Permian, Jurassic and Tertiary, which are important coal-forming eras. The carbon content of coal is generally 46-97%, ranging from brown to black, with dull to metallic luster. According to the different degrees of coalification, coal can be divided into peat, lignite, bituminous coal and anthracite. Tunneling refers to the mining and excavation of roadway in coal mine.
