自从五十年代中期把肥料粒级的硝铵作为廉价炸药用于矿山爆破作业以来,矿用炸药的发展就进入一个全新的阶段。以肥料粒级的硝铵为主要组分的炸药在露天矿和地下矿相继出现,逐渐取代了传统的炸药。到目前为止,这类炸药(主要是铵油和浆状炸药)在矿山工业比较发展的国家已占绝对优势,而且这一优势在最近的将来仍将保持。美国1973年矿山铵油炸药消耗量约占总消耗量的75%,
The development of mining explosives has entered a whole new phase since the fertilizer-grade ammonium nitrate was used as a cheap explosive for mine blasting operations in the mid-1950s. The explosives, mainly composed of ammonium nitrate with fertilizer grade, appeared one after another in surface and underground mines and gradually replaced traditional explosives. To date, such explosives (mainly ammonium and grout explosives) have gained an absolute advantage in the more developed countries in the mining industry and this advantage will remain in the near future. The United States in 1973 mining ammonium oil explosives consumption accounted for about 75% of total consumption,
