FIELD: explosive works.
SUBSTANCE: invention is related to explosives and may be used in explosive works that are performed with borehole charges in drilled cores. Composition of explosive that contains oxidiser and combustible additive is suggested. In capacity of oxidiser composition contains mixture of dense and porous granulated ammonia nitrate in proportion of 2:1 in the form of polydisperse structure or mixture of dense granulated and powdered ammonia nitrate in proportion of 5:1 in the form of polydisperse structure. In capacity of combustible additive composition contains mixture of liquid oil products and thermal power plant fly ash microspheres in proportion from 6:1 to 3:1. Invention provides high efficiency of explosive composition action at safe level of its sensitivity to mechanical effects.
EFFECT: provision of high efficiency of explosive composition action at safe level of its sensitivity to mechanical effects.
