摘要
在西峪煤矿人行斜井穿越流沙层期间,通过采用超前小导管管棚预支护、周边开挖、放小炮、拱架初期支护、料石砌碹、壁后注浆二次衬砌等技术措施,可以减小对围岩的扰动,使人行斜井成功穿越流沙层,这对井巷工程施工具有一定的指导意义。
During the period of pedestrian inclined shaft passed through the quicksand Layer in the xiyu coal mine,it may reduce the adjacent perturbation by some technical measures,for example,pre-support by the small pipe tube awning,peripheral excavating,discharging low gun,primary support by arch center,rock materials brickwork,back-filled grouting and secondary lining,and so on.So it can enable the pedestrian inclined shaft successfully pass through the quicksand layer,and it has certain instructive significance ...
