METHODS OF ACHIEVING SAFE STATIONARY EXPLOSIVE TRAINS,
Abstract
Four methods are suggested for safe interruption of explosive trains that do not rely on a movable barrier. Initiation of the detonator in each method will generate stress waves of sufficient pressure level to detonate the secondary explosive only when the devices are armed. The sufficient level, PF (the function mode), is provided by correctly timing dual detonators to initiate the secondary explosive by the shock-to-detonation transition. When the detonator initiations are not properly timed, the maximum pressure level PNF is provided, which is low enough to preclude initiation of the secondary explosive. (The logic for timing the detonators is not discussed). The ratio PF/PNF, one measure of a method's potential safety, varies from 2.4 to 20 for the four methods, according to some approximations.
