ABSTRACT:
A cap-sensitive emulsion explosive capable of being used in packaged explosive products. The explosive contains ammonium nitrate prills of a bulk density of 0.70 to 1.00 g/cc, with a particle density of 1.25 to 1.40 g/cc. A polysuccinic anhydride based emulsifying agent is used as an emulsifying agent. Packaged explosives prepared according to the present invention have improved package stability, and allow for control of the ratio of shock energy to heave energy.
