摘要
针对清水营煤矿深部软岩巷道出现的严重变形破坏,在原有支护方案的基础上,提出一种新型中空注浆锚索结构的加固方案,加固后支护结构整体稳定,无断锚情况发生,围岩整体性得到显著加强。
In view of the serious deformation of a deep soft rock roadway in Qingshuiying coal mine,put forward a new supporting scheme of hollow grouting anchor cable based on the original one. And the supporting structure integral stability after the reinforcement, without breaking the anchor, the integrity of surrounding rock has been significantly strengthened.
