摘要
针对霄云煤矿主井井筒施工至泥岩含水层时,矿井涌水量突然增加的情况,通过比较,决定采用动态注浆技术进行堵水,并计算得出止浆垫的厚度、注浆孔数目及倾角,经实测,本次注浆达到了预期效果。
Aimed at the situations of the water inflow increased suddenly when the construc- tion of vertical shaft was carried out to the mudstone aquifer in Xiaoyun Coal Mine, the dynamic grouting was adopted to seal the water, and the thickness of grouting pad, the numbers of grou- ting holes and their dip angles were calculated. The measurement results showed that this grou- ting achieved the desired effect.
