摘要
分析了深部软岩巷道硐室的支护状态稳定因素,结合现场实际情况,总结了深部软岩巷道破坏后二次支护的方法和原则。采用锚网索喷注浆的联合支护工艺,可实现现场支护的理想效果。
The supporting state stabilizing factors of the deep soft rock roadway chamber are analyzed.In combination with the actual situation,the secondary support methods and principle after the deep soft rock roadway damage are summed up.By the combined support with anchor cable network spray,the ideal results of the actual support are realized.
