| 摘 要： | 围岩的变形和破坏状态在掘进、稳定、回采等不同阶段具有明显差别,利用"扩容一稳定理论"来设计煤巷锚杆支护,以控制围岩的扩容变形,形成次生关键承载层,提高承载圈的承载能力使围岩趋于稳定,解决煤巷锚杆支护强度不够的难题。

| Abstract: | The deformation and failure state of surrounding rock in driving,stable and stoping stage are different.Using dilatancy and stability theory to design the tunnel bolt support to control the deformation of the surrounding rock,forming the secondary bearing layer and promoting the bearing capacity of load-bearing ring to stabilize the surrounding rock.The bolt support can solve the problem of low support strength. |

| Keywords: | dilatancy stability load-bearing ability support parameter |
