对锚杆支护三角组合技术的组合结构进行了介绍,对比常规锚杆支护,分析了三角组合技术在锚杆支护中抑制岩石移动的作用,并利用FLAC模拟方法,观察在三角组合技术下巷道围岩位移的变化,得出了三角组合技术保护巷道的优越性。
This paper introduces the combined structure of the bolt support triangular combination technology. Comparing with the conventional bolt support, this paper analyzes the effect of the triangle combination technology to restrain the rock movement in the bolt support. By using the FLAC simulation method, Under the change of the surrounding rock displacement of the roadway, the superiority of the triangle combination technology to protect the roadway is obtained.
