邵寨煤矿主井前期采用普通法施工，在进入白垩系洛河组含水地层后，由于涌水量太大，采用工作面预注浆、壁后注浆、井壁设置截水槽、增大排水能力等综合防治水措施加以治理，收效甚微，井筒难以继续向下掘进，不得不改用冻结法施工。冻结法施工历时189d ，顺利完成。
邵寨煤礦主井前期採用普通法施工，在進入白堊繫洛河組含水地層後，由于湧水量太大，採用工作麵預註漿、壁後註漿、井壁設置截水槽、增大排水能力等綜閤防治水措施加以治理，收效甚微，井筒難以繼續嚮下掘進，不得不改用凍結法施工。凍結法施工歷時189d ，順利完成。

A common method was applied to the early stage construction of the mine main shaft in Shao-zhai Mine ,when the mine shaft was in an aquifer of Cretaceous Luohe Formation ,due to the water in‐flow too high ,a pre-grouting at the shaft sinking face ,backfill grouting ,cut-off trench set in the shaft liner ,enlarged water drainage capacity and other comprehensive water prevention and control measures were applied to control the water inflow .The results were small ,the mine shaft was hard to continue the downward sinking and the common construction method had to change to the ground freezing method construction .The ground freezing method construction was taken 189 days and was success‐fully completed.
