立井井筒工作面预注浆堵水技术的研究与应用

Research and Application of Face Beforehand Grouting Intercept Water Technology in Shaft

平宝公司首山一矿主井井筒施工中,利用工作面预注浆堵水技术,顺利通过强含水层,取得了较好的效果,对类似水文地质条件的井筒施工具有参考价值。

Duringthe construction in Shoushan No. 1 Coal Mine in Pinghao Company, using the technology of face beforehand grouting intercept water technology through the strong aquifer, has got a better effect. It has a reference valu for the shaft construction on the similar hydrology and geography conditions.
