摘要
介绍了两对矿井成功地采用聚能管定向断裂爆破技术，实现了大断面岩巷快速掘进，分析了定向断裂爆破技术原理及其技术经济效果。
This paper presents the directional fracturing blasting technology with energy concentrating tube which bas been successfully used in two coalmines,realizing the speedy drivage of in rock roadways with large cross section.The technical principle of the directional fracturing blasting and its technic economic effect are also dissussed in the paper.
