近日，中國冶金科工集團華冶資源開發有限責任公司在武鋼大冶鐵礦東副井工程治理井筒涌水中，實施靜水止漿墊施工工藝獲得成功。
去年12月，武鋼礦業公司大冶鐵礦東副井工程當豎井掘至-41米時，因涌水量過大被迫停工。今年3月，華冶資源在業主招標治水中中標。
幾個月(yue)來，在(zai)工(gong)(gong)程(cheng)施(shi)(shi)工(gong)(gong)難度(du)大、沒(mei)有(you)施(shi)(shi)工(gong)(gong)經(jing)(jing)驗可借鑒的情況下，針對(dui)如(ru)何使井(jing)筒底部砼(tong)墊層達到所要(yao)求強度(du)、控制(zhi)水(shui)(shui)泥漿(jiang)液比例及輸送管(guan)路如(ru)何下送到水(shui)(shui)下工(gong)(gong)作(zuo)面(mian)等問(wen)題，工(gong)(gong)程(cheng)技(ji)術人員開展治水(shui)(shui)攻關。經(jing)(jing)過多(duo)種方案比較(jiao)和多(duo)次實(shi)(shi)驗后，對(dui)東(dong)副井(jing)實(shi)(shi)施(shi)(shi)了靜水(shui)(shui)止漿(jiang)墊施(shi)(shi)工(gong)(gong)工(gong)(gong)藝，獲(huo)得成功(gong)。東(dong)副井(jing)工(gong)(gong)程(cheng)已(yi)于8月(yue)份復工(gong)(gong)。目前，井(jing)筒涌水(shui)(shui)量已(yi)經(jing)(jing)控制(zhi)在(zai)3立(li)方米/時，項目部將繼續對(dui)井(jing)筒明顯出水(shui)(shui)點進行封堵(du)及壁后注漿(jiang)工(gong)(gong)作(zuo)。
