最近20年来,国外露天矿广泛采用了铵油炸药,以及称为浆状炸药的各类含水炸药。同其它简单炸药相比,浆状炸药的密度、威力、爆速和爆压都比较高。这类炸药的出现,可以使其制备、运输及深孔装药实现机械化,从而大大提高了这些工作的劳动生产率。国外用以下三种方法实现散粒炸药及含水炸药制备的机械化: ·在制药厂将炸药包装(主要用聚乙稀袋);

In the last 20 years, a wide range of ammonium oil explosives have been used in open-air mines in the world, as well as various types of explosives known as slurry explosives. Compared with other simple explosives, slurry explosives density, power, detonation velocity and explosive pressure are relatively high. The advent of such explosives has made it possible to mechanize their preparation, transport and deep-hole charge, thereby greatly increasing the labor productivity of these jobs. Mechanization of the preparation of shotgun explosives and water-based explosives is achieved abroad by the following three methods: • Explosive packaging (mainly polyethylene bags) in pharmaceutical factories;
