Underground roof support is a common profile in the mining industry and coal support field. Underground roof support are mainly assembled by bending and welding, and are often used in mine tunnels, secondary support of mine tunnels, and support of mountain tunnels. The advantages of the underground roof support have the characteristics of high pressure resistance, long support time, easy installation and no deformation.
In the practical application of underground roof support, for the accumulation of water in the underground of the tunnel and the humid stratum, the 20Mnk material is often used as the first choice. Ordinary shallow ground support, Q235 is the mainstream under dry conditions. Most of these materials will be processed into combined stents. A general beam is equipped with two support legs. There are few bends in actual processing.
The underground roof support will escort the safe production of the mine. China Coal Group will continue to innovate and use the technical advantages of customized processing of supporting equipment, and increasingly improve production and delivery capabilities, better serve our customers, so that everyone can buy the most Reliable, reliable and affordable underground roof bracket!
