摘　　要：针对中煤集团塔山矿副平硐中部花岗岩-泥岩-灰岩的岩性变化交界区域(1 470~1 850 m)存在的涌水现象,进行注浆堵水治理。通过深、浅孔组合的方式,浅孔及跑浆区域以水泥-水玻璃双液浆为主,深孔以单液水泥浆为主,并选用高分子堵水材料进行补充注浆,结束后进行导流排水。结果表明:涌水量由治理前的46.2 m^(3)/h降至3.4 m^(3)/h左右,降幅达92.6%。有效封堵了涌水裂隙,加固了井壁,堵水效果良好。According to the water gushing phenomenon in the granite-mudstone-limestone boundary area(1470-1850 m)in the middle part of the secondary adit of Tashan mine of China Coal Group,the grouting and water blocking treatment was carried out.Through the way of combination of deep and shallow hole,the cement-water glass double liquid slurry was main in shallow hole and run-off area,and single liquid cement slurry was Main in deep hole,after the end of the diversion drainage.The results showed that the water inflow decreased from 46.2 m^(3)/h to 3.4 m^(3)/h,and the reduction rate was 92.6%.The water gushing crevice is effectively blocked,and the well wall is reinforced,and the water blocking effect is good.
