LI Zhi-xiang
Abstract：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.
