摘要:

结合福建省武平某银多金属矿施工填充站TZK1、TZK2投料井工程，详细介绍了矿山投料井施工的难点与对策：通过对钻探设备的优化组合，结合钟摆钻具原理，辅以护壁堵漏，研制分离式注浆专用阀，顺利下入套管及注浆固井，圆满完成了该投料井工程的施工任务。

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.
