摘要
针对山西××矿过断层巷道压力大、围岩变形明显、难于支护的特点,采用中空注浆锚索新型支护材料与锚杆相结合支护方式进行围岩控制,现场矿压观测表明,取得了较好的效果,具有一定的借鉴意义。
In view of the characteristics of large pressure, obvious deformation of surrounding rock and difficult support in roadway passing through faults in a coal mine in Shanxi Province, a new supporting material of hollow grouted anchor cable combined with bolt is adopted to control the surrounding rock. The field strata control observation shows that good effect has been achieved, which has certain reference significance.
