摘要
本文总结了干河矿回风立井井筒壁后注浆堵水的技术经验,在井壁涌水高达54.4m3/h的条件下。采用先“打包围战”的方式,以出水部位为中心,先从外围开始,进行包围封堵、上下夹攻、四面合围,再“打集中歼灭战”的注浆堵水方案,效果良好。
This article summarizes the technical experience of block up water grouting in the wall back of discharge air shafts in Ganhe Colliery, which is something like surrounding and grouting the water burst in the drain opening from the outside, the upper and the＇ bottom in the condition of 54.4m3/h waterburst.
