我们曾在某矿区的坑内和地表，使用人造金刚石孕镶钻头（以下简称人孕金刚石钻头），在7～10级的硅化白云岩、复杂角砾岩、板岩和辉长岩类岩层中进行水平孔孔内钻进试验，完成八百多米工作量，最深钻孔达213米，平均时效1.64米/小时，台月效率达470米，取得了较好的钻进效果，比同地区、同岩层的直斜孔人造孕镶金刚石钻进效率都高。这次实践、为今后在水平孔中推广使用人造孕镶金刚石钻头开辟了途径，同时也对钻进工艺有了新的看法和认识，现将在施工中所取得的效果和需要注意的几个问题做一介绍和讨论。
We have used artificial diamond inlaid drill bits (hereinafter referred to as human pregnant diamond bits) in pits and surfaces in a mining area, in silicified dolomites, complex breccias, slate and gabbro formations of grades 7-10 Horizontal hole drilling test to complete the workload of more than 800 meters, the deepest hole of 213 meters, the average time of 1.64 meters / hour, Taiwan and Taiwan efficiency of 470 meters, and achieved better drilling results than the same area , With the vertical rock drilling artificial diamond inlaid diamond drilling efficiency are high. This practice opens up a way for popularizing the use of artificial impregnated diamond bits in horizontal holes in the future, and at the same time, it has taken a new view and understanding of the drilling technology. Now the results achieved in construction and the few that need attention An introduction and discussion of the problem
