Abstract:
1. An explosive device for initiating a relatively insensitive main explosive charge comprising: a booster with a main booster housing; an explosive core containing an explosive composition that is the most explosive composition of the booster, the explosive composition being sensitive to initiation by a blasting cap or detonating cord; the explosive core having a top surface, side surface and bottom surface and at least one initiation aperture; the at least one initiation aperture having a cup shape with an interior side wall and an interior bottom wall, the side wall and bottom wall of the at least one initiation aperture are exposed surfaces of the explosive composition of the explosive core; and the explosive core having a cup bottom thickness measured from the bottom wall of the at least one initiation aperture having a cup shape to the bottom surface of the explosive core; the at least one initiation aperture having a cup shape for physically coupling a blasting cap to the explosive core with the explosive core containing the most sensitive explosive of the booster; a sheath explosive that covers the explosive core at least partially on the side surface, bottom surface and top surface wherein the sheath explosive is comprised of a melt cast-able explosive composition; and a blasting cap positioned within the cup-shaped initiation aperture in direct contact with the exposed surface of the explosive composition of the explosive core.
