COMPONENTS AND METHODS FOR USE WITH EXPLOSIVES

摘要

An apparatus and method is provided to reduce interference resulting from activation of explosive devices. One type of interference is charge-to-charg e interference, and another type of interference is pre-shock interference between a detonating cord and an explosive, such as a shaped charge. To redu ce interference, one or more shock impeding elements are placed proximal one or more explosives to impede propagation of shock caused by detonation of the explosives. The shock impeding elements include a porous material, such as a porous liquid or solid. In another arrangement, a shock barrier may be positioned between a detonating cord and an explosive to reduce pre-shock interference. In yet another feature, an encapsulant may be provided around one or more shaped charges to enhance structural support for the shaped charges.
