FIELD: explosives.
SUBSTANCE: group of inventions relate to performance of blasting operations and can be used for preparation of granulated explosives and explosive slurries for use in mining industry. Composition of invention contains, in essentially stoichiometric proportions, 1:4 to 4:1 mixture of porous granulated ammonium nitrate with dense granulated ammonium nitrate and combustible component additive. Blasting composition may further contain emulsion for producing explosive slurries. Preparation of composition comprises simultaneous mechanic mixing of two above types of ammonium nitrate at 1:4 to 4:1 ratio and adding combustible components.
EFFECT: stabilized characteristics and optimized sensitivity to initiating impulse.
