在井下使用铵油炸药大大地降低了一次爆破的炸药费用。与惯用的硝化甘油炸药比较,铵油炸药的敏感性也较低。当正确地使用它时也较安全。但是为了保证使用铵油炸药的最大安全性,需要了解有毒气体存在的危险性,以及在压气装药时所产生的静电。已经制定了安全界限和安全规则,允许用电雷管进行眼底起爆的炮眼使用压气装药但是对有毒气体的危险性还研究得很不透彻。在1959—1960年间Du-pont公司与美国矿务局合作研究粒状硝铵——二号燃料油混合
The use of ammonium explosives downhole significantly reduced the cost of one blasting charge. Compared with the conventional nitroglycerine explosives, ammonia explosives are also less sensitive. It is safer when used correctly. However, in order to ensure the maximum safety of using ammonium explosives, you need to know the dangers of poisonous gases and the static electricity generated when you compress them. Safety boundaries and safety rules have been established that allow the use of gas charge in blastholes that have been detonated with electric detonators but have not been thoroughly studied for the dangers of toxic gases. Between 1959 and 1960, Du-pont worked with the U.S. Bureau of Mines to study the combination of granular ammonium nitrate-two fuel oil blends
