摘　　要：针对钻眼爆破掘进工艺爆破效果不佳等问题,以同煤某矿巷道为研究对象,分析了影响爆破效果的关键因素,并对其掏槽方式和关键爆破参数设计的理论基础进行详细分析,最后确定爆破时的掏槽方式和炮眼直径、深度、布局以及炸药消耗的具体指标,为提升该巷道的爆破效果奠定基础。In view of the problems such as the poor blasting effect of the drilling blasting driving technology,taking a mine roadway in the same coal as the research object,this paper analyzes the key factors affecting the blasting effect,and makes a detailed analysis on the theoretical basis of the cutting way and the design of the key blasting parameters,and finally determines the cutting way and the specific indexes of the hole diameter,depth,layout and explosive consumption during the blasting to improve the blasting effect of the tunnel.

关 键 词：巷道 掘进 爆破 效果 优化
