摘　　要：刘园子矿副立井井壁出现粉化破裂点,且井筒内有较大的渗漏水现象,矿井生产存在严重的安全隐患。通过对井壁破裂原因分析,提出采用卸压法进行井筒治理,采用井圈加固井壁破裂段、中深孔双液壁后注浆堵水加固漏水段井壁、在井壁严重破坏段设置卸压槽的综合治理方案。后期监测结果显示治理效果良好,为矿井生产提供了一定的安全保障。Auxiliary shaft of Liuyuanzi Mine with dusting breakdown point and water leakage, threatens the safe mining.Pressure relief to shaft was put forward after analyzing the reason of shaft wall break, the well ring reinforcing broken wall section and deep hole double liquid wall after grouting with blocking water wall and borehole wall severely damaged section provided with a pressure relief groove, with good effect and safe ensurance.
