Abstract

The water-in-oil emulsion explosives of this invention contain a water-immiscible organic fuel as a continuous phase, an emulsified inorganic oxidizer salt solution as a discontinuous phase, an emulsifier, gas bubbles or an air entraining agent for sensitization, and from about 1% to about 30% by weight of the composition urea for stabilization against thermal degradation with reactive sulfide/pyrite ores. The invention also relates to a method of using such explosives.
