FIELD: means of blasting of commercial explosives with employment of wave and electrical initiation facilities. SUBSTANCE: the primer detonator has a hollow tubular casing filled with secondary explosive, and an initiator secured in the casing; the filled cavity is made in the form of a successively increasing row of ducts, the lowest of which is engageable with the initiator and its dimensions are selected from the mentioned row (relations are given), and the dimensions of the other ducts are bound with relations (formulas are given) at which the explosive is ignited in the duct with the lowest dimensions by a low-power pulse from the waveguide with further transition of the process to a stable detonation. EFFECT: reduced power intensity of initiated pulse and mass and dimensional parameters of the device. 6 cl, 8 dwg |
