摘要
针对漳村煤矿2305风巷二次动压巷道围岩变形破坏严重的问题,提出了强力锚索补强配合化学注浆的综合加固技术。综合加固方案现场实施后,巷道变形相对其他加固方式大幅降低。二次动压巷道强力锚索补强配合化学注浆加固技术可以大幅提高围岩的整体性,降低围岩的变形量,能够保证巷道在服务期间正常使用。
In view of the severe deformation and failure of the surrounding rock of the secondary dynamic pressure roadway in 2305 return-air roadway in Zhangcun coal mine, comprehensive reinforcement technology with intensive cable bolting and chemical grouting was proposed. After the comprehensive reinforcement method was implemented, the deformation of the roadway was greatly reduced compared with other reinforcement methods. Intensive cable bolting combined with chemical grouting reinforcement technology can greatly improve the integrity of the surrounding rock and reduce the deformation in a secondary dynamic pressure roadway, which can also ensure the normal service condition of the roadway during its service oeriod.
