Description
Technical Field
The utility model relates to a coal mine equipment technical field, specific theory especially relates to a colliery tunnelling supporting device.
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.
At present, a coal mine excavator does not have protective capacity in the excavating process, coal cinder or rock blocks can fall from the top layer of a hole after excavation, the fallen coal cinder or rock blocks damage machinery and can also be accumulated on the surface of mechanical parts to influence forward excavation construction equipment, meanwhile, dust generated in the excavating process can reduce visibility, and the dust is accumulated on the surface of the machinery after static precipitation to obstruct normal transmission of the machinery. Because the traditional temporary support is supported by adopting a single body matched with a top beam, the top plate of the empty top area is not supported in time after the roadway is tunneled, all manual operation is performed, the safety threat is large, the labor intensity is high, the supporting speed is low, and the accident that the waste rock falls off from the top plate and people are injured can often happen.
