摘要
利用BJQ空气间隔器,研究推广矿山新的装药方法,提高爆破质量,降低爆破成本。这种方法不仅降低了炸药的单耗,获得了良好的经济效益,而且提高了挖装效率,减少了爆破的危害。
Extension mine new charge methods to improve the quality of blasting to reduce blasting costs using BJQ air spacer.This approach not only reduces the unit consumption of explosives,get a good cost-effective and improve the efficiency of dredging equipment to reduce the hazards of blasting.
