摘要
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。
Composite structures of bolt support triangle compared with the conventional bolt support, analyze the combination technology are introduced and triangle combination technology to inhibit the action of the rocks move in the bolt support. Observing the change of displacement of surrounding rock of roadway by using FLAC simulation method under the triangle combination technology. The superiority of the triangle combination technology of roadway protection is obtained.
