EXPLOSIVE ENERGY-INITIATABLE BLASTING CAPSCONTAINING A POROUS IGNITION AND DETONATIONSYSTEM AND METHODAbstract of the DisclosureA non-electrically initiated blasting cap containinga porous ignition charge which is permeable for flow of a gasstream therethrough and initiatable in response to explosiveenergy of an explosive gas mixture, including conduit means foremplacing a confined stream of the explosive gas in position with-in the blasting cap for the responsive initiation.Also provided is a system, including a plurality ofthe above blasting caps spaced apart for detonation of one ormore main charges, together with additional conduit means for con-veying the explosive gas to the plurality of blasting caps forthe emplacement, and means for ignition of the thus emplacedexplosive gas.Method is provided for making a blasting cap containinga porous ignition charge, making a porous ignition charge andinitiating a non-electric blasting cap for the initiation of amain explosive charge.- 1 -
