分析了煤矿井巷工程岩石爆破作业现状及其效率低下的原因。对采用1～ 1 0段或 1 0段以上毫秒电雷管和变传统的拱形开挖爆破法为线性开挖爆破法的科学性、合理性进行了探讨。
The status quo of rock blasting operation and the reason of low efficiency in mine tunnel engineering are analyzed. The feasibility and feasibility of the linear excavation blasting method using 1 ~ 10 segments or more than 10 ms electric detonators and changing the traditional arch excavation blasting method are discussed.
