摘 要:针对红岭煤矿掘进-445 m水平车场井底水仓局部冒顶、后期可能变形大等问题,提出了全锚索喷浆联合支护技术,根据实际条件设计具体参数。经过实践及现场监测,全锚索注浆联合支护技术能够有效地保障断层破碎带水仓巷道掘进安全及支护要求,起到了主动加固顶板的作用,有效增大了井底水仓容量,效果较好。In view of the problems of local roof fall and possible large deformation in the later stage of the bottomhole water sump of the-445 m horizontal parking lot during the excavation of Hongling Coal Mine,a fully anchor cable grouting combined support technology is proposed,and specific parameters are designed according to actual conditions.Through practice and on-site monitoring,the fully anchored grouting combined support technology can effectively ensure the safety and support requirements of the excavation of water storage tunnels in fault fracture zones,play an active role in reinforcing the roof,effectively increase the capacity of the bottom water storage,and achieve good results.
