FIELD: explosives. SUBSTANCE: invention concerns industrial second-class ammonia-nitrate substances useful in mining industry when performing blasts in open and underground works, except gas and dust explosive mines and dry and wet bottomholes. Invention consists in developing explosive compositions, which are low dusting upon pneumatic charging, possess high detonation capacity, and have no critical density. The compositions are manufactured according to ballistite technology and contain (in wt %): ammonium nitrate, 59.0- 60.0; diethanolnitroamine dinitrate (sensitizer), 8.0-12.0; ballistite powder and colloxylin (fuel binding agents), 24.46-25.34 and 4.0-6.0, respectively; and mineral oil (process additive), 0.3-0.5. EFFECT: improved performance characteristics.
