摘 要: | 柠条塔煤矿因烧变岩接受大气降水补给,沿烧变岩底部由东南向西北汇流补给3-1煤层,造成3-1煤中央辅运大巷左侧区域富含地下水,煤壁渗水量较大,给矿井的长期安全生产造成一定的威胁。通过煤壁左侧注浆,有效封堵了地下水源,煤壁渗水量明显减小,注浆效果良好。

Study on Construction Technology of Curtain Grouting in Coal Roadway |

Abstract: | Rainfall that recharged to burnt rock of Ningtiaota coal mine flowed to 3-1 coal seam from southeast to northwest along the bottom. Groundwater becomes so rich in 3-1 coal seam transport roadway and groundwater seepage so large that long-term safety was threatened. By grouting on the left coal wall, ground water is sealed off effectively, the amount of water seepage is reduced significantly. Grouting treatment is proved to be very efficient. |
