摘　　要：在煤矿井巷掘进工程中,随着钻孔机械化程度的不断提高,中深孔爆破亦随之增加,研究与之相适应的装药爆破技术,对加快岩巷快速掘进速度,解决煤矿采、掘关系失调的矛盾,提高井巷工程掘进爆破效果和安全性等都具有现实意义。In process of mine excavation,the blasting technique of medium-depth hole has been increased with the development of drill mechanization.It is important to study the relative charging and blasting technique for accelerating excavation speed of stone drift,normalizing the relationship between mine and excavation,increasing the blasting results and enhancing the safety,etc.

关 键 词：井巷掘进 正向装药 反向装药 爆炸特性 破碎规律 爆破安全
