| 摘 要： | 锚杆支护作为一种内在的支护形式,有非常好的自身稳定性和柔性特征,可以实现主动支护、早期承载,可以达到很高的支护强度,对冲击矿压巷道具有良好的适应性。冲击矿压巷道锚杆支护的作用原理为:对围岩体整体强度的强化作用、对围岩应力状态的改良作用、对围岩变形破坏的约束作用和对冲击剩余能量的吸收作用。

| Abstract: | As an inner supporting manner,anchored-bolt has excellent self stability and flexibility for active supporting,early bearing load.For its high strength,anchored-bolt is very fit for supporting roadway with burst danger.This paper presented supporting principles of anchored-bolt as follows.Anchored-bolt strengthens whole strength of surrounding rock,makes stress state better,restricts deformation and damage of surrounding rock and absorbs residual energy of rock-burst. |

| Keywords: | rock-burst supporting with anchored-bolt energy absorbing action |
