In order to improve the efficiency of blasting work of the coal mine rock heading face, this paper used the middle and deep hole drilling and blasting techniques. The results show the circulating footage is significantly increased, the materials consumption is reduced through the layout way and blast-hole charge structure and parameters according to the selected embrasure. The conclusion is that the middle and deep hole blasting technology can be applied in the excavation work of coal mine.%为了提高煤矿岩巷掘进工作面爆破作业工效,采用了中深孔钻眼爆破技术,结果表明:按选定的炮眼布置方式和装药结构及参数,循环进尺明显提高了,材料消耗降低了,结论:中深孔爆破技术适合在煤矿岩巷炮掘工作面推广应用.
