Abstract：A mine shaft development mode ,block development and block ventilation was applied to Tangkou Mine.Due to the ventilation resistance of the main ventilator was steadily increased ,the ne-gative pressure of the ventilation reached at 3 564.6 Pa. An air income ventilation shaft and an air re‐turning ventilation shaft were required to be sunk in the south part of the minefield.Both shafts would pass through the Quaternary and Jurassic F2 fault broken zone and watery base rock. The water inflow was high and a ground freezing method construction was applied to the Quaternary and Jurassic bro‐ken zone section.A borehole water leakage ,the conventional method construction and a double con‐crete shaft liner structure were applied to the watery section of the base rock in order to ensure the safety and high efficient construction of the mine shaft.
