ABSTRACT:
Cap sensitive emulsion explosive compositions comprising a discontinuous aqueous oxidizer salt phase, a continuous carbonaceous fuel phase, and closed cell void containing materials are disclosed which exhibit increased sensitivity, as measured by the 1/2 cartridge air gap sensitivity test, due to a reduced water content in the range of from about 4% to less than about 10% by weight of the emulsion matrix which is used to prepare the composition.
