Abstract
The present invention relates to improved blasting agents. More particularly, the invention relates to a water-in-oil emulsion blasting agent containing sodium nitrate (SN) in an amount of from about 40% to about 70% by weight of the total composition. The water-in-oil emulsion blasting agents of this invention have a water-immiscible liquid organic fuel as a continuous phase; an emulsified aqueous inorganic oxidizer salt solution as a discontinuous phase; particulate inorganic oxidizer salt; an emulsifier; and optionally a density reducing agent. Preferably the blasting agents contain from about 10% to about 40% ammonium nitrate (AN) in addition to SN.
