摘要
简要阐述了在巷道掘进中难爆岩石提高炮眼利用率的一些实践,总结了有效对付难爆岩石的一些钻眼爆破方法,对于其他矿山难爆岩石具有一定价值。
In this paper, the practice of improving the holes utilization ratio in roadway excavation through diffi- cult blasting rock is presented, and some effective drilling blasting methods against hard rock are also summarized, which will do a certain favor for other mines in hard rock blasting.
