安居煤矿副井井筒竣工后,井筒涌(淋)水量较大(约18 m3/h),给安全生产及设备维护带来严重的影响。本文介绍了安居煤矿副井井筒注浆堵水工艺,采用特殊材料XYPEX,以简易注浆+疏导+补强为整体方案。治水结束后,下井口、马头门处已无大幅淋水状态,整个井壁可见大面积发白干燥状态,彻底解决了井筒淋水问题。
After the completion of the coal mine shaft in Anju Coal Mine, a large amount of water (about 18 m3 / h) was poured in the well bore, which seriously affected the safety in production and equipment maintenance. This paper introduces the grouting and plugging technology of the coal mine auxiliary wellbore in Anju Coal Mine. The special material XYPEX is adopted to simplify grouting, drainage and reinforcement. After the treatment of water, the next wellhead, Ma Tau door has no significant water showering state, the entire shaft wall can be seen a large area of white dry state, completely solve the problem of wellbore watering.
