Abstract：In the heading and lining construction of a mine inclined shaft in No.5 Mine of Pingmei ,a previous goaf was met and there was great mine water inflow occurred in the heading face. The max water inflow was 40 m 3 /h. With many investigations ,there were abandonment mine roadways in the front of the heading face. Therefore a series of the water prevention and control measures conducted , such as the pre-grouting at the heading face and other rapid construction technology. A water detection and water drainage were applied to the three abandonment mine inclined shafts and a goaf. An advance pipe shield type grouting and support was applied to consolidate the soil mass. Then the mine inclined shaft heading and the shaft liner concreting were conducted and the mine inclined shaft was successful ‐ly passed through the goaf in the alluvium.
