Blasting caps initiatable by thermal detonation energy of an explosive gas mixture, and blasting system

摘要

A nonelectric blasting cap initiated by thermal detonation energy from an explosive gas mixture, in which the required open space for charging and detonating the explosive gas mixture is contained, together with the conduit means, in an end closure member; and the open space is shaped to provide a shell to end closure crimp without impairing flow of explosive gas through the conduits.
