一、概述最近十多年,人造金刚石钻头在采矿工业中已经获得了应用。事实上,镶嵌细粒金刚石钻头的理论研究已近三十年了,但在采矿工作中完全公认它,仅仅是最近五年的事情。对于用筛选的金刚石制造的镶嵌细粒金刚石钻头来讲,其主要优点是具有稳定的钻孔速度和较长的使用寿命。特别是钻头在钻岩作业中很少更换,从而大大地减少了停机时间。在采矿工业中获得应用和公认的第二种 I. Overview In the recent ten years, artificial diamond bits have been used in the mining industry. In fact, the theoretical study of inlaid fine diamond bits has been almost 30 years old, but its full acceptance in the mining industry is only the last five years. The main advantage of diamond-like inserts made of screened diamond is the stable drilling speed and long service life. Drills, in particular, are rarely changed during drilling operations, greatly reducing downtime. The second is the application and recognition in the mining industry
