Mine roof support is a new type of mining support material, which is widely used in underground roadways, but also for bridge and railway maintenance. Mine roof support has the best treatment effect on unstable surrounding rocks, and also guarantees safe mining production an important part of it.
The anchor drill rig used in the installation of the mine roof support is tightened upward, the section modulus of the steel strip is very small, and it is easy to closely adhere to the surrounding rock of the roof. , Make the anchor loosen the surrounding rock to form a whole. The W-shaped steel belts are used to connect multiple scattered anchors to form an integrated bearing structure. The W-shaped steel belts and anchors combined support technology is generally applicable to rock formations with moderate stability. In the support of coal mine roadway, the roof support of the mine has large force, safety and stability, strong durability, safety and reliability, which can improve the service life of the roadway, reduce the maintenance rate of the roadway, reduce the occurrence of safety accidents and ensure the safe production of the coal mine. .
U-shaped mine roof support are mostly used in mines and roadways. We all know that the application conditions in these areas are very bad, so we need to ensure the quality of the mine roof brackets so that they can play their maximum effectiveness.
