Abstract
A booster explosive device (10) has a housing (12) within which is contained an explosive primer charge (14). Mechanical fastener components such as exterior screw threads (32) on housing (12) and interior screw threads (34) on an explosive accessory charge (20) may be engaged with each other in order to provide a charge assembly (30) comprised of device (10) and accessory charge (20). The outer peripheral surface (26) of accessory charge (20) is optionally concave so that accessory charge (20) optionally serves as a shaped charge to provide enhanced radial explosive output. Explosive primer charge (14) is configured so that the output tip (44b) of a detonator (44) contained therewithin is positioned below at least about 50 percent by weight of primer charge (14) and within the accessory section (10c) of device (10).
