CAP SENSITIVE EXPLOSIVE COMPOSITION CONTAINING FROM 20 TO 40% OF SOLID PARTICULATE AMMONIUM NITRATE

摘要

This invention relates to a cap-sensitive explosive composition consisting essentially of a water-in-oil emulsion explosive and from 20 to 40% by weight of the explosive composition of solid, particulate ammonium nitrate wherein said water-in-oil emulsion explosive comprises a discontinuous oxygen-releasing salt phase, a continuous water-immiscible organic phase comprising an organic fuel, an emulsifier component comprising at least one emulsifier comprising a lipophilic moiety and an hydrophilic moiety wherein said lipophilic moiety is a saturated or unsaturated carbon chain containing from 40 to 500 carbon atoms, and void-containing material wherein the discontinuous oxygen-releasing salt phase comprises a perchlorate selected from the group consisting of ammonium perchlorate, sodium perhclorate and mixtures thereof.
