我公司3#竖井于1992年10月6日建设竣工并投入使用,至今已运行了13年。该竖井井筒净径4.5m,井深450m,提升设备为多绳摩擦式提升机。竖井所处位置水文地质情况复杂,淋水大,围岩松散,导致井壁在浇铸成形后仍然有比较大的涌水量,达到9.86m3/h,涌水呈酸性,铜离子含量高。 The 3 # shaft of our company was completed and put into use on October 6, 1992 and has been in operation for 13 years. The shaft borehole diameter 4.5m, depth 450m, lifting equipment for the multi-rope friction hoist. The location of the shaft is very complicated with the hydrogeology, watering is large and the surrounding rock is loose. As a result, the well wall still has relatively large water inflow after it is formed, reaching 9.86m3 / h. The water gushing is acidic and the copper ion content is high.
