Product Description
Introduction of Cheap Price Rock Bolt Coal Mine Roof Support Anchor Rod
The anchor is the most basic component of the roadway support in contemporary coal mines. He strengthens the surrounding rock of the roadway and makes the surrounding rock itself support itself. Now the anchor is not only used in mines, but also used in engineering technology to strengthen the main body of slopes, tunnels and dams. As a tensile member deep into the stratum, the anchor is connected to the engineering structure at one end and into the ground layer at the other end. The whole anchor is divided into a free section and an anchoring section. The free section means that the tension at the bolt head is transmitted to the anchor. The function of the area is to apply pre-stress to the anchor.Parameter of Cheap Price Rock Bolt Coal Mine Roof Support Anchor Rod
