摘要
我国煤矿坑道钻探与地面煤田钻探比较，在技术上发展得慢一些。但自70年代后期我国把发展综采作为煤炭工业的一项重要的技术政策之后，情况发生了很大变化，煤矿坑道钻探以前所未有的速度发展起来。80年代在新型坑道钻机的研制开发上取得了很大的进展，90年代在完善坑道钻机的同时钻探工艺也有新的突破，开始走上设备与工艺全面发展的轨道。本文对近20年来在该领域取得了主要成绩作了简要回顾，并指出存在的问题。
Compared withthe surface drillng,the underground drilling was deveioped slowly technically,however,the situation was changed largelysince the late of 1970s,when the development of fully mechanized mining was decided as an important technical policy,and the underground drilling was developed with the unprecedented speed.In 1980s,a greater progress was obtained in the development of underground driller,and in 1990s,a newbreakthrough also was attained in the drilling technology,the equipment and technology are fully development.In this paperm,the main achievement in this field optained in near 20 years is reviewed briefly and the existed problems are pointed out．
