摘要
葫芦素煤矿主井、副井为超大井筒,井筒漏水点较多、漏水量较大,给井筒防治水工作带来很大难度。通过选择科学合理的注浆方案,实施井壁接茬注浆,采用隔水帷幕注浆封堵含水层及冻结孔,突破了传统的井筒注浆模式,且取得了良好效果。
The main shaft and auxiliary shaft of Hulusu Coal Mine belong to extremely large mine shaft,There are many drops and large amount of water leakage in these shafts, so it is difficult to carry out water prevention and control work of coal mine. According to choo- sing scientific and reasonable grouting scheme ,joint grouting was put into practice in shaft wall ,water curtain grouting was used to real- ize the water blocking of aquifer and the freezing holes. It breaks through the traditional shaft grouting scheme and has achieved good effects.
