METHOD OF PREPARING WATER-CONTAINING BLASTING MATERIAL CHARGE, WATER-CONTAINING LIQUID (OPTIONS), AND WATER-CONTAINING BLASTING MATERIAL Russian patent published in 2006 - IPC C06B47/14 C06B21/00 C06B45/00 

FIELD: explosives.

SUBSTANCE: invention relates to blasting operations in open-cast mines and provides a method for preparing water-containing blasting material involving addition, to dry ammonia/ammonium nitrate blasting material, of water-containing liquid, in particular, mixed aqueous solution of oxidizing and combustible substances, said solution being unsaturated regarding concentrations of components thereof at given temperatures. Resulting mixture is stirred under ambient temperature conditions until temperature of mixture reaches ambient temperature, during which stirring finished water-containing blasting material is formed, from which blasting material charge is prepared. Two options for composition of water-containing liquid and water-containing blasting material are further proposed.

EFFECT: increased efficiency of water-containing blasting material charge and also improved energetic quality and balanceness of water-containing liquid.
