| 摘 要： | 长城矿业公司基建副立井出现了严重的井壁破坏,造成井筒建设停产.通过分析,认为井筒通过7号煤小窑采空区是井筒破坏的主要原因.为此有针对性地实施了"密集井圈 卸压槽 壁后注浆 锚杆加固"为主的抢险工程,井筒目前正常提升,取得了良好的治理效果,并且丰富了井壁破坏治理措施.

| Abstract: | There was serious mine shaft liner failure occurred in the mine shaft construction period of the mine auxiliary mine in Changcheng Coal Mining Company and the shaft liner failure caused a pause to the mine shaft construction. After the analysis, the paper held that when the mine shaft sinking through a goaf in No. 7 seam of a small mine was the main cause of the mine shaft failure. Therefore, an emergency repair project with the intensive shaft ring, strata pressure releasing slot, shaft liner back grouting... |
