THERMAL DETONATION ENERGY INITIATABLE BLASTING CAPS AND DETONATION SYSTEM

摘要

A noneletrically initiated blasting cap containing an initiation charge ignitable in response to action of thermal detonation energy of an explosive yas mixture, including conduit means for emplacing a confined stream of the explosive gas in detonating position in the blasting cap for the responsive ignition. Method, including passing a stream for the explosive gas along the emplacement route, for purging the system prior to the detonation, is also provided.
