    Abstract:

    The paper detailed the difficulties of feeding batching mine construction and the countermeasures according to the feeding batching mine engineering practice of TZK1 and TZK2 in Fujian. By the optimum combination of drilling equipments, based on the pendulum assembly principle, assisted by wall protection & leakage stoppage, with the development of separation-type grouting valve, the construction was fulfilled with case setting and grouting cementation.
