摘　　要：随着采矿工业深部开采量加大,坚硬磨蚀性矿岩增多,对潜孔钻头的寿命和工作效率提出了更高的要求。文章提供了一种新型聚晶金刚石潜孔钻头,实验表明,聚晶金刚石潜孔钻头与传统硬质合金潜孔钻头相比,可大大提升钻头寿命,提高钻头的工作效率,降低消耗,是钻进中硬岩层的理想钻头。Along with the deep mining in mining industry and hard and abrasion resistance rock increasing, the higher work efficiency and long life of the down-the-hole bit are re- quested. This paper provides a new kind of PDC down-the-hole drill. The experimental result shows that compared with the traditional carbide drilling down-the-hole bit, the PDC drilling down-the-hole bit can greatly enhance the bit life and improve the bit work efficiency, and also can reduce the consumption. It is ideal bit drilling in hard rocks.
