摘　　要：针对特厚煤层掘进巷道过断层群遇到的围岩支护困难、进度缓慢、安全性差的情况,通过采用超前段支护锚注加固、掘进段锚注一体加固、滞后段架棚二次注浆加固等围岩控制技术,实现了对断层群围岩的加固和控制,过断层期间速度显著提升、变形和位移明显减少,保证了巷道的安全掘进与后期使用。In view of the difficulties,slow progress and poor safety of surrounding rock support encountered in driving roadway through fault group in extra-thick coal seam,by adopting surrounding rock control techniques such as bolting and grouting reinforcement in leading section,bolting and grouting integrated reinforcement in driving section and secondary grouting reinforcement of frame shed in lag section,the reinforcement and control of the surrounding rock of fault group are realized,the speed is significantly increased and the deformation and displacement are obviously reduced during the period of passing through the fault.It ensures the safe excavation and later use of the roadway.
