摘要
针对井筒渗水和突水的条件差异,分别使用井筒壁局部注浆法("补丁式"封堵法)治理井筒壁渗水,使用人工隔水层法("置换式"封堵法)治理井筒突水,并将2种方法应用于西北地区冻结法建井的煤矿井筒渗水和突水灾害治理,结果显示治理段井筒壁无渗水,揭露冻结管环形导水空间突水由稳定水量90 m3/h降低为2 m3/h。
Basing on the difference of water seepage and water inrush, the technology of partial grouting into strata and shaft is researched to solve the hazard of water seepage, and it could be named patch sealing water method(PSW), but the water inrush could be treated by artificial aquifuge, and the technology could be named replacement sealing water method(RSW). The two technologies are applied to seal shaft water seepage and water inrush in coal mine in northwest, finally, the amount of water seepage from shaft got close to 0 m3/h and water inrush decreased from 90 m3/h to 2 m3/h.
