ABSTRACT:
A method of preparing a gassed water-in-oil emulsion explosives composition from a gasser solution of an inorganic nitrate, an ammonium species and an optional accelerator which is added to an emulsion explosive composition, reacts and forms gas bubbles is disclosed. The emulsion explosive composition is composed of a discontinuous aqueous phase, a continuous water immiscible organic phase, and an emulsifier. The reaction between the gasser solution and the emulsion explosive composition is such that the emulsifier does not undergo chemical attack.
