在克里沃罗格矿区的露天铁矿,强化开采大量极坚硬的铁矿石要求从根本上完善穿爆工作,改善为采装准备矿岩的质量。目前,使用现代牙轮钻机完成穿爆工作,完全可以保证形成使露天矿以10万吨/昼夜以上的生产能力进行有节奏地生产所必须的穿孔储备矿岩量。近年来,完善穿爆工作是围绕寻求新型炸药、合理的爆破参数和方法、大 In the open pit iron ore mines at the Kryvo Roogh mining area, the intensified mining of a large amount of very hard iron ore requires a fundamental improvement of the blasting work and the improvement of the quality of the ore prepared for loading. At present, the use of modern cone drills to complete the blasting operation completely guarantees the formation of the amount of perforation reserve ore necessary for the rhythmic production of open pit mines with a production capacity of over 100,000 tons per day and night. In recent years, perfecting the work of wearing explosives is to seek new types of explosives, reasonable blasting parameters and methods, large
