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。
幾個月來(lai)，在(zai)工(gong)(gong)(gong)程(cheng)(cheng)施(shi)工(gong)(gong)(gong)難度(du)大(da)、沒有施(shi)工(gong)(gong)(gong)經(jing)(jing)驗可借鑒的情況下，針對如何(he)使井筒底部砼墊(dian)層達到所要求(qiu)強度(du)、控制(zhi)水泥(ni)漿(jiang)液比例及輸(shu)送管路如何(he)下送到水下工(gong)(gong)(gong)作(zuo)面等(deng)問(wen)題，工(gong)(gong)(gong)程(cheng)(cheng)技術人員(yuan)開(kai)展治(zhi)水攻關。經(jing)(jing)過(guo)多種方案比較和多次實驗后，對東副井實施(shi)了靜水止漿(jiang)墊(dian)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)，獲得成功。東副井工(gong)(gong)(gong)程(cheng)(cheng)已(yi)于8月份復工(gong)(gong)(gong)。目(mu)前，井筒涌水量已(yi)經(jing)(jing)控制(zhi)在(zai)3立方米/時，項目(mu)部將繼續(xu)對井筒明顯出(chu)水點進行封堵及壁后注漿(jiang)工(gong)(gong)(gong)作(zuo)。
