ABSTRACT:
The invention relates to a method of safely preparing stable water-in-oil emulsion explosives. After formation of the emulsion explosive, it is cooled in a heat exchanger which uniformly cools the emulsion. The physical characteristics of the heat exchanger also limit the extent of detonation if it should occur. In order to improve stability of the emulsion explosive, the oxidizer is blended with the emulsion subsequent to cooling the emulsion.
