摘　　要：为了提高硬岩倾斜巷道的掘进速度和成形质量,研究了中深孔光爆技术;优化了中深孔光爆参数,使炮眼平均深度比工程前期提高0.3m,并在桃园煤矿Ⅱ1人行上山掘进施工中进行了应用,结果表明,斜巷掘进平均循环进尺比工程前期提高0.505m;炮眼平均利用率达89%,比工程前期提高14%;"底高"现象基本消失,加快了工程进度。To improve driving speed and forming quality of inclined roadway in hard rock, medium - deep hole smooth blasting was studied, the blasting parameters were optimized, which deepened 0. 3m of the average hole depth, the technology was applied in driving of Ⅱ1 personnel raise in Taoyuan Coal Mine, the results showed that, average circulation footage increased 0. 505m; average shot hole utilization rate was 89% , improved by 14% ; the ＂high floor＂ phenomenon was basically eliminated. Project progress was accelerated.
