Abstract

Disclosed is a water-in-oil emulsion explosive composition comprising a continuous phase consisting of a carbonaceous component; a disperse phase consisting of an aqueous solution of inorganic oxidizer salt; an emulsifier; an organic gas-retaining agent; and an aluminum powder. The present explosive composition can show especially high underwater explosion energy.
