立井井筒转变为平巷施工时,一对井筒施工到底后,往往是交替进行临时或永久提升改装,来保证井下巷道的快速施工。而对于单井筒施工,井筒到底后,在改装条件又尚未成熟的情况下,井底应用矸石仓,沿用凿井时期的吊桶提升来施工巷道,收到良好的效果。 查扉村矿新立井井筒,于1978年10月破土,至1982年7月落成。井筒净径4.85米,净断面18.17米~2,井深493.5米,井筒淋水2
When a vertical shaft is converted into a laneway, the construction of a pair of wellbores is often alternated with temporary or permanent upgrades to ensure the rapid construction of underground tunnels. However, for the construction of single wellbore, after the wellbore is completed, under the conditions that the modification conditions are not yet mature, the application of waste rock bottom at the bottom of the well and construction of the roadway along the lifting bucket during sinking have received good results. Cha Fei Village Mine new shaft, broken ground in October 1978, completed in July 1982. The borehole has a net diameter of 4.85 meters, a net section of 18.17 meters ~ 2 and a depth of 493.5 meters
