Background

Coal mines refer to places rich in coal resources 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. Coal is the most important solid fuel, is one of combustible organic rocks, and can be divided into four types, namely peat, lignite, bituminous coal and anthracite, according to the coal gasification degree. At present, in construction operations such as mining, tunnel, often need install protector in the tunnel, but current tunnel protector is not convenient for install because the height in the tunnel is sometimes different, and we have provided a tunnel protector for coal mining convenient to install for this reason.
