The development of human beings can not be separated from the mining of underground resources. The underground mine areas are large, including areas of the ground, underground and surrounding facilities, and it is difficult to excavate. In order to prevent the collapse of mines and surrounding areas during the excavation process and ensure the safety of coal miners, support measures is particularly important. Rock bolts are the main tools used by coal mines in China and other major coal mines. The application of rock bolts not only greatly reduces the material consumption, but also effectively enhances the stability of the roadway and ensures the safe production of mines. From the initial slagging support, shed support to rock bolt support, with the change of supporting methods, fewer and fewer accidents occur, and mining efficiency enhance greatly. The rock bolt support is used for drilling, grouting and anchoring on the inner wall of the roadway. According to the different geological rocks, the location and depth of the designed drilling are also different, so as to achieve the best supporting effect. Sinorock® provides self drilling bolts for various mining projects. We can also customize the product according to the customer's requirements. Thanks to advanced mining technology with self drilling anchor, modern practices have significantly improved the safety of mines.
