摘要
枣泉煤矿东回风斜井在通过中侏罗统直罗组粗砂岩强含水层段,井筒掘进工作面出现大量涌水,受粗砂岩孔隙水大量淋水的影响,无法进行混凝土喷射,给施工带来很大安全隐患。采用注浆防治水施工作业后,项目实施段巷道顶板及两帮涌水明显减少,基本达到规定的指标要求。
East coal mine of Zaoquan return air shaft in the Middle Jurassic Zhiluo Formation gritstone strong aquifer section, shaft excavation working face a lot of gushing water, under the influence of coarse sandstone pore water pouring water in large quantities, can not be sprayed concrete, bring great trouble to construction. The Grouting water Sealing work, the implementation of the project section of roadway roof and two for water significantly reduced, basically reached the requirements specification.
