大贾庄铁矿3号副井-450m水平巷道掘进至距井筒100m左右时,放炮后,发生了较大突水事故,突水量210m3/h左右。在30min内,巷道全部被水淹没,水深平均200mm。根据具体情况,借鉴隧道工程建设经验,决定采用止浆墙注浆法治理突水。方案实施后,取得了成功,并收到了良好的效果。

When a-450m level roadway heading had a distance of about 100m to No.3 Mine Auxiliary Shaft of Dajiazhuang Iron Mine,a large water inrush accident was occurred after a blasting conducted and the water inrush quantity was about 210m3 /h.Within 30 minutes,the mine roadway was fully flooded and a water depth was 200mm in average. According to the certain condition and with the con struction experiences of other tunneling projects,a grouting method with a grouting cushion was deter mined and applied to the water inrush control. After the plan was conducted,a successful water control was obtained and an excellent effect was obtained.
