FIELD: blasting operations.

SUBSTANCE: invention relates to industrial explosives, in particular, to emulsion explosive composition (EEC) containing the following in wt%: ammonium nitrate 74–76, mineral oil 6–7, water 12 and emulsifier – the rest. Emulsifier is obtained by mixing lecithin, gum-arabic, bentonite, a foaming agent for fire extinguishing – a concentrated aqueous solution of a surfactant, specifically a synthetic hydrocarbon foaming agent and neutralized black contact with water.
