摘要
通过理论分析、实验室模型试验得出岩巷掘进微差爆破最优的爆破参数，研制了新型高延迟毫秒电雷管，并为现场工业试验所验证，炮眼利用率提高了7.8％，装岩时间缩短了20％～30％。
Through theorical analysis and laboratory model tests, the optimum blasting parameters ofmillisecond blasting for rock drifting have been gotten. A new millisecond electric detonator has been developed and it was proved by site commecialr test. Therefore, the utilization of boreholes increases by 7. 8%and the charging time is shortened by 20- 30%.
