| 摘 要： | 曙光矿专用行人巷为半煤岩巷道,巷道变形破坏严重。利用霍克-布朗(Hoek-Brown)强度准则计算了专用行人巷的松动圈范围,并对巷道围岩破坏进行了岩层影像探测研究,基于松动圈支护理论提出了相应的支护措施,并对支护效果进行了现场观测,取得了良好应用效果。

| Abstract: | Aiming at the serious deformation and damage of coal-rock walking roadway in Shuguang mine,the paper works out the range of loose circle of the roadway with Hoek-Brown criterion,and conducts the image surveying study on the rock bed for the surrounding rock damage situation.Based on the loose circle supporting theory,the corresponding supporting measures is proposed,and the field observation shows that it has achieved a good application effect. |
