| 摘 要： | 巷道围岩岩性松散、破碎,应力集中程度较高,围岩体整体强度偏低,在高应力作用下巷道围岩剪胀变形较为强烈,局部承载结构破坏诱发锚网支护大面积失效,承载结构稳定性降低。实施锚网—锚索耦合支护技术,根据位移分析原理,确定支护系统二次耦合支护的最佳时间(段),在关键部位实施支护体和围岩的再次耦合,最大限度地发挥围岩的承载能力,从而使支护体的支护抗力降到最小。

| 关 键 词： | 破碎围岩 锚网—锚索耦合桁架支护 最佳时间(段) |

| Abstract: | The lithology of roadway host is loose and broken,which has higher degree of stress concentration and low strength of rock body as a whole.The deformation of rock dilatancy is more strongly wnder high stress.Local host structural damage induced large-scale failure of mesh bolting.The stability of bearing structure reduced.The combined support technology with anchor wire and cable was used. |

| Keywords: | broken host coupling truss support with anchor wire and cable best time |
