我队是1982年开始应用金刚石钻进技术的，在两个矿区施工条件及钻头选型基本确定之后，就如何使用好钻头，以提高寿命和效率等技术问题作了一些摸索，也取得了良好效果。我队人造孕镶金刚石钻头使用简况如表1。我们选择合理钻速方法的要点是：第一，结合实际，利用数理统计方法对正常磨损的典型钻头进行综合分析，确定出较为符合本地情况的一些规律性钻速指标，如：合理钻速范围，均匀钻速小区间，初磨钻速，后期钻速。
Our team started to apply diamond drilling technology in 1982. After the construction conditions and bit selection in both mining areas were basically determined, we made some groping on how to use the bit to improve the technical problems of life expectancy and efficiency, and achieved good results effect. My team artificial impregnated diamond drill bit usage profile in Table 1. The main points of our choice of a reasonable drilling speed method are: First, combined with the actual use of mathematical statistics to analyze the normal wear of a typical drill bit to determine some more in line with the local conditions of the regular rate of drilling indicators, such as: a reasonable rate of penetration rate , Uniform drilling speed between the small area, the initial drilling speed, drilling speed later.
