Ammonium nitrate (AN) is the main component-oxidizing agent in production of explosive compositions (EC), and its share accounts for nearly 90-95% of the total weight of EC. Application of ammonium nitrate as an oxidizing agent for explosive compositions has a long history. The so-called “mixed on the job” explosives (named Igdanit in the USSR and ANFO in foreign countries) were created on the basis of ammonium nitrate and fuel oil (AN-FO) and came into common use in ore and coal mining sectors. They replaced dynamite and TNT-based explosives in blasting processes for water-free holes, including underground conditions of non-gassy and non-dusty mines.
