| 摘 要： | 平煤六矿北风井井筒掘进到378m位置时,工作面开始涌水,最大涌水量达到100m3/h,无法进行掘进施工。根据对涌水情况和地质条件的分析,决定采用工作面预注浆技术治理涌水。经工作面预注浆,井筒涌水量降到了2m3/h以下,取得了良好效果。

| Abstract: | Pingdingshan six mine north Shaft position heading into the 378 m,the face began gushing water,the maximum water inflow to 100 m3/h,the construction can not be boring.Based on the gushing water and geological conditions of the analysis of the situation,decided to adopt a pre-grouting technology governance face gushing water.The face pre-grouting,borehole water inflow dropped to 2 m3/h or less,and achieved good results. |
