Technical Field
The utility model relates to a supporting technical field specifically is a colliery tunnelling supporting device with regulatory function.
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. 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.
At present, a protection device is needed when a coal mine is tunneled to support the coal mine at the top, however, the existing support device is poor in adjustment, and therefore the adjustment function of the support device needs to be improved.
