立井施工采用泄水孔治水实践

Water Prevention by Drainage Hole Practice in Shaft Construction

袁店一井煤矿东风井立井掘砌施工期间,采用打泄水孔与井下已有巷道连通,井壁淋水及井筒涌水通过泄水孔下泄至已有巷道,并通过永久排水系统排至地面的治水方案,有效地解决了水患问题,为井筒的顺利掘砌创造了良好条件,为类似矿井的水害治理提供了参考经验。

During Yuandian Yijing Coal Mine Dongfeng shaft digging,using drainage holes and underground existing tunnel has connected ,spraying and gushing water through the drainage hole discharged into the existing tunnel,and the permanent drainage system to the ground,effectively solve the problem of flooding,and created a good condition for the shaft digging,provide a reference for the similar mine water disaster control.
