摘要
针对某巷道掘进周边孔光面爆破中出现的问题,应用空气间隔装药光面爆破技术及其对炸药传爆方式的改进,最终取得了比较好的爆破效果。实践证明,这项技术操作简单,爆破成本低,能够取得非常可观的经济效益,有很大的推广应用价值。
To solve the problem in driving of a drift with peripheral hole smooth blasting, the fir-deck charge in peripheral hole smooth blasting and its improvement on the detonation mode have been applied, and better blasting effect has been obtained, The practical application has proved that the technique is simple in old,ration, low cost in blasting, very profitable and valuable in extended application.
