METHOD FOR FORMING OF DETONATION WAVE IN EXPLOSIVE CHARGE Russian patent published in 2000 - IPC

FIELD: explosive charges, applicable for initiation of deep-hole and other charges of low-sensitive and commercial explosives, for example, in mining art. SUBSTANCE: an additional explosive charge is blasted, and an impact momentum is produced by transfer of the initial detonation momentum directly to the inert insert of the additional charge. Shock waves arise in the insert that interact in the insert axis with formation of a high-pressure zone. The intensified impact momentum is transferred to the main explosive charge. EFFECT: enhanced safety of blasting. 2 dwg
