METHOD FOR INITIATION OF HIGH EXPLOSIVES Russian patent published in 1999 - IPC

FIELD: blasting of high explosives. SUBSTANCE: prior to blasting the charge, the layer of explosive to be initiated is heated, and a preset nonuniform temperature field is produced, then a compression impulse is excited with an amplitude and/or duration lesser than required for initiation of stable high-speed detonation in the layer to be initiated before its heated and edge shape determining together with the temperature field the required shape of the detonation wave edge. EFFECT: reduced probability of unauthorized blast of explosive charge, enhanced efficiency of authorized blast as a result of initiation of stable high-speed detonation wave with the required edge shape. 1 dwg
