摘要
东欢坨矿在-230m水平大巷向北二采区开拓延伸施工中发生F2’断层滞后透冲积层出水,经过采用地面注浆加固封堵断层破碎带的方法,对该断层进行了治理。井下巷道清理恢复验证,出水点处无水,经过数月观测无出水现象,该施工方法取得成功。
Lagging water leakage from the alluvium occurred when the-230m level roadway extended to North No.2 Section and met Fault2′ in Donghuantuo Coalmine.Surface grouting method was used to reinforce and seal the fault fracture zone.Through clearing up and restoring the roadway,it is proved that the adoption of this method was successful,no water inrushing again even after several months observation.
