Explosive composition, process for activating and firing an explosive and envelope for the explosive.

摘要

Economical and effective cap sensitive explosive compositions are manufactured by combining appropriate proportions of a non-cap sensitive organic liquid containing oxidizing groups with a porous substrate. The preferred liquid is nitromethane or nitromethane diluted with a hydrocarbon. The preferred substrate is a finely divided ionic nitrate powder. The explosive compositions are rendered cap sensitive and highly brisant by providing a substrate which disperses the organic liquid while maintaining this fluid in intimate contact with dispersed air. The preferred finely divided ionic nitrate substrates used in the present invention are prepared by grinding to the desired particle size, preferably less than 500 microns.
