摘要
文中针对晋煤集团胡底煤矿深部软岩巷道的失稳破坏问题,分析了导致深部软岩巷道变形破坏的主要因素和变形破坏机理,提出了注浆加固+高预应力锚索的联合支护方案,加固支护方案有效控制了巷道的变形,成功解决了深部软岩巷道失稳破坏问题。
Aiming at the instability damage problem of the soft rock roadway in deep c0al mine in Hudi Coal Mine of Jincheng Coal Group, the main factors and the deformation breakage mechanism leading to the deformation and fail- ure of deep soft rock roadway were analyzed, a support scheme combining the grouting reinforcement and the high prestressed anchor cable was proposed, the deformation of roadway was effectively controlled by the supporting scheme successfully solving the instability damage problem of the deep soft rock roadway.
