METHOD OF PREPARING EXPLOSIVES Russian patent published in 1998 - IPC

Abstract RU 2103247 C1

FIELD: explosives. SUBSTANCE: when preparing explosives mainly useful in minerals industry for primary breaking of rock by open-cut and underground methods, a part of oxidant is preliminarily dissolved in water on heating, liquid fuel is added under stirring in quantity 25-55% based on weight of oxidant solution, suspension obtained is combined with remaining part of oxidant to provide content of liquid fuel 4-7 wt %, liquid fuel being added to oxidant solution with rate not exceeding 0.018 g/s per 1 g of oxidant solution. Prior to be combined with remaining part of oxidant, suspension can be cooled until full crystallization. When combining the two components, additional introduction of liquid fuel is possible in quantity 2.5% based on weight of remaining part of oxidant. Liquid fuel may be mazut, mineral oil, vegetable oil, diesel fuel, or their mixture. EFFECT: improved preparation process. 4 cl
