FIELD: explosives.
SUBSTANCE: invention relates to blasting operations and can be used in blasting of rock massif in open-pit mines and mines. Invention provides composition of granulated explosive containing, in specified proportions, granulated ammonium nitrate, liquid or liquid and solid combustible additives, and, as inert material, crystalline sodium chloride oiled with liquid petroleum derivative in amount 0.5-2 % by weight. Invention also discloses a method for preparation of granulated explosive comprising preliminarily oiling crystalline sodium chloride with liquid petroleum derivative, mixing granulated ammonium nitrate with oiled crystalline sodium chloride and then with liquid or liquid and solid combustible additives.
EFFECT: increased detonation sensitivity, improved reliability of detonation, and improved homogeneity of mixing composition components in preparation procedure.
