Abstract：When No.5 Mine Shaft of Xincheng Gold Mine was sunk at a depth of 4 m,a water inflow was occurred.At the location of the mine shaft,the thickness of the sand stratum and the weathering zone were thick.If the water inflow was not controlled,with the downward sinking the mine shaft,the water would be penetrated downward and would cause the difficulties to the late construc-tion.According to the certain conditions,a concrete water sealing layer was applied to the water seal-ing at the temporary lock of the mine shaft.At the mine shaft collar section,several temporary mea-sures were applied to control the water inflow.When the mine shaft construction was at base rock sec-tion,a backfill grouting was conducted for the water sealing,would effectively control the water inflow at the mine shaft collar in the weathering section and could ensure the safety construction of the mine shaft and the project quality.
