摘要
煤矿井下钻孔事故是制约煤矿正常开采工期的关键因素之一。总结了煤矿井下坑道钻探钻孔事故常用的处理方法,分析了埋钻、卡钻、断钻三类常见钻孔事故的特征及原因,探讨了该三类事故的处理方法,对煤矿井下钻孔事故的处理具有一定的借鉴意义。
The drilling accident of underground tunnel of coal mine is one of the key factors to restrict mine normal production period. The paper summarizes the coal mine tunnel drilling acci- dent handling methods, analyzes the characteristics and the reasons of the three kinds of common drilling accident such as drill bury- ing, sticking, breaking of a rod, and discusses the handling meth- ods for the three kinds of drilling accident, has a certain reference significance for such drilling accident disposal.
