摘　　要：针对丘卡卢-佩吉铜金矿L2竖井涌水量大的情况,L2竖井先后进行了2次工作面注浆,探注位置分别在497.5~554.5 m和550.2~625.2 m,掘进50 m,最大涌水量由原来65.00 m^(3)/h,减少到12.00 m^(3)/h,并且对2次壁后注浆的特殊情况进行了针对性处理,涌水量由23.00 m^(3)/h,减少到4.00 m^(3)/h,注浆治水效果明显。In response to the high water inflow in the L2 shaft of the Chukalu Pegi copper gold mine,the L2 shaft has undergone two rounds of grouting at the working face,the exploration and injection positions were 497.5-554.5 m and 550.2-625.2 m,respectively.The excavation was 50 m,and the maximum water inflow increased from the original 65.00 m^(3)/h reduce to 12.00 m^(3)/h,and targeted treatment was carried out for the special situation of grouting behind the wall twice,reducing the water inflow from 23.00 m^(3)/h to 4.00 m^(3)/h.The grouting has a significant effect on water control.
