Problems solved by technology
[0002] In the process of coal mining, the side of the road is supported by the side beam and the iron wire fixed support plate to support the coal mining roadway. This kind of support method is simple, and the operation is all manual cooperation. The randomness is large. The iron wire is hinged, and the firmness cannot be guaranteed. The support of the mining roadway is difficult to guarantee, the strength of the iron wire is limited, and it will cause rust and fracture in the wet environment of the roadway for a long time. Once the support connection breaks, it will lead to safety accidents
