ABSTRACT:
Water-in-oil emulsion blasting agent compositions are provided which are non-cap sensitive yet detonable under high heads of water and which contain as the sole oxidizing salt ammonium nitrate, an ammonium nitrate to hydrocarbon fuel weight ratio in the range of about 95:5 to about 93:7, a preferred wax to oil weight ratio in the range of from about 1:1 to about 1:4, void containing material to yield a final density at the time of manufacture of from about 1.20 to about 1.25 grams per cubic centimeter and optionally up to about 12 parts by weight of auxiliary fuel per 88 parts of the above composition. The blasting agents are capable of cartridge-to-cartridge propagation even when detonated under high heads of water when packaged in cardboard containers.
