Mine steel arch supports are mainly used in mine tunnels, railways, slopes and tunnels to reinforce the main body of the dam. Its function is mainly to ensure the stability of mine tunnels and underground engineering surrounding rocks. Steel arch support has the advantages of low cost, good supporting effect, simple operation, flexible use, and less construction clearance.
Steel arch support is mainly used as a support in underground mines. It is widely used in underground mine tunnels, working face cuts, caverns and other areas of tunnel support, and has a better effect on handling unstable surrounding rocks. Other rigid supports supported by steel arches have retractability and stable and reliable load-bearing capacity, adapt to the load and deformation of soft surrounding rock, high section utilization rate, convenient support, small maintenance, high support recycling rate, and reduce pit wood Use, the environmental protection benefit is very obvious.
Steel arch support not only solves the problem of roadway support, but also can be used for the support of other roadways and chambers with large cross-sections, and can also be used for the reinforcement of landslides, dikes and dams. The application of steel arch support in coal mine roadway support saves a lot of steel and wood. At the same time, it also greatly reduces the labor intensity of workers, improves the labor environment of workers, and brings significant economic and social benefits to the high efficiency and safe production of coal mines. .
