With the development of economy, the coal as main energy demand is becoming more and more huge, coal as the main production in the coal industry is also facing the deep development of the problem, with the increase of excavation depth, roadway supporting faces many difficulties, in order to improve the support strength, enhance security, we need to analyze the application of self drilling hollow bar support in coal mine internal.
Self drilling hollow bar is a direct acting within the surrounding rock of roadway,it is different from the old ways such as wood beams , in other words, it is from the past passive support on the outside of the rock into the internal active support, so that we can reduce the deformation of roadway, improving the bearing capacity of self drilling hollow bar support.
At present,there are many coal mining in China has reached more than 1000 meters depth above, not only larger mining depth, but also the complicated geological structure, there exists the possibility of mine disaster,which brings very great difficulty in self drilling hollow bar coal mining support.
So, to be the best supplier of hollow bar is Sinorock’s aim and also it is our responsibility.
To be the best manufacturer for anchor bolt products, Sinorock has formed a strong Research & Development team, in the team there are several senior engineers in the fields of material, mechanical engineering, electrical and mechanical engineering and so on.
To be the best manufacturer for hollow anchor bolt products, Sinorock focuses on product quality extraordinarily, the inspections in Sinorock include incoming inspection, production, finished products inspection.
To be the best manufacturer for hollow anchor bolt products, Sinorock improves the service quality ceaselessly, we have established a comprehensive service system. It concludes 7*24 hours online consultation, great products packaging solutions and professional after-sales service.
