METHOD OF EXCITATION OF DETONATION WAVE IN EXPLOSIVE CHARGE Russian patent published in 1997 - IPC

FIELD: excitation of explosive charge detonation, for instance, in mining art. SUBSTANCE: first additional charge is blasted. If inert spacer 3 is available, a shock wave travels in charge 1. When the wave passes to unloading element 7, an unloading wave reflects to charge 1. Second additional explosive charge 4 is blasted. Unloading element 7 is made of material with dynamic stiffness lower than that of explosive of charge 1. EFFECT: facilitated procedure. 1 dwg
