| 摘 要： | 在介绍国内外潜孔锤钻进配套设备及工具性能、规格的基础上，对比了其在钻进深度、钻进效率、使用寿命、钻进参数选择等方面的差异。指出制约当前潜孔锤钻进的技术问题主要有水文地质问题、岩石破碎程度、风压、孔径、泡沫冲洗液等因素，并对不同岩性地层条件下如何选择适用钻头类型进行了探讨。

| Abstract: | Based on an introduction to down-the-hole hammer drilling associated facilities and tool performances both domestic and abroad, contrasted differences between drilling depth, drilling efficiency, and service life, drilling parameter section. Pointed out present restricting factors have hydrogeological problems, rock fragmentation, compressed air pressure, borehole diameter, foam flush fluid etc., and discussed how to select bit type under different rocks. |
