Tunnel roof support is a material widely used in various projects. Tunnel roof support can be used in roadway support, tunnel support, tunnel and other field support in mining operations. With the development of society and the continuous improvement of the safety production awareness of miner enterprises, as well as the gradual strictness of the country's requirements for mineral production, professional tunnel roof support profiles for coal mines have also received more and more attention. Tunnel roof support is to ensure the safety of mining production important link.
The tunnel roof support has higher rigidity and strength, the flexural section modulus is increased by dozens of times, the hard effect during cold pressing can increase the tensile strength by 28-46%, the tunnel roof support can make the load uniform, Expand the support range of mines
The application of the tunnel roof support in coal mine support saves a lot of cost and reduces the waste of steel and wood. At the same time, tunnel roof support also improved the construction environment and greatly reduced the labor intensity of the workers. The tunnel roof support brings significant economic and social benefits to the efficient and safe production of coal mines.
