Initial Discussion on Large Velocity Artesian Ground Freezing Technology of Gaojiapu Mine
REN Dong-bin
Abstract：Gaojiapu coal mine is located in the northwest of Shanxi Province in Binchang mining area , the main shaft through the Cretaceous strata thickness up to 668.5m ,among them the Luohe strata thickness up to 371.28m ,the strata has large thickness ,rich water ,large water pressure.Gaojiapu main shaft using freezing method construction ,through freezing the shaft construction ,accumulatio-ning the west of our country freezing construction experience similaring as high velocity strata ,this pa-per has a introduction about the freezing construction scheme and problem during the freezing con-struction ,try to discuss how to optimize freezing scheme of similar strata.
