摘　　要：望云煤矿回风立井掘进穿越K5灰岩含水层时,涌水量突增至75 m^3/h左右,导致施工困难。为保证后续施工安全,采用工作面预注浆方法来封堵涌水。因该段围岩破碎,采用静水位止浆垫预注浆技术,对破碎围岩加固堵水,取得较好效果。When the mine air return shaft of Wangyun Mine sunk through K5 limestone aquifer,the mine water inflow suddenly increased about 75 m^3/h and caused the mine shaft construction in difficulty.In order to ensure the safety of the follow-up construction,the pre-grouting method at the mine shaft sinking face was applied to seal the water inflow.Due to the sectional surrounding rock broken,the pre-grouting technology with grouting cover and static water level was applied to reinforce the broken surrounding rock and to seal the mine water.Thus a good effect was obtained.
