摘　　要：潜孔锤跟管钻进技术是近年来逐步发展、成熟的一种钻井技术,具有钻进速度快、效率高、成孔率高、干式钻进、孔斜率低等优点。通过总结在矿井钻孔注浆工程中该技术的施工方法、操作工序、注意事项等内容,为今后类似工程积累了宝贵经验。注浆钻孔施工技术的应用,不仅减少了防灭火工程的总体资金投入,而且还对注浆防灭火工程的治理效果起到至关重要的作用,已成为神东公司注浆防灭火工程不可或缺的关键技术。Down-the-hole hammer and following drilling technology is a kind of drilling technology which has developed gradually in recent years. It has many advantages, such as fast drilling speed, high efficiency, high porosity, dry drilling and low hole slope. Through summarizing the construction method, operation procedure and precautions of this technology in the mine borehole grouting project, we have accumulated valuable experience for similar projects in the future. It not only reduces the overall capital investment of the fire prevention project, but also plays a vital role in the control effect of the fire prevention by grouting. It has become an indispensable key technology in the fire prevention project by grouting for Shendong Company.
