| description | FIELD: initiation of explosive charges in plane or curvilinear surface for formation in the explosive charge of the blast wave front of the preset shape. ^ SUBSTANCE: according to the invention, by means of electric detonators the input points of the matrix are blasted, from them the detonation waves through the branching channels of the matrix filled with an explosive spread to the terminal sections blasting the main explosive charge and form a blast wave in it. The detonating pulse from each electric detonator is separated minimum into two pulses, which are supplied with a selected diversification to the explosive circuits made according to the AND circuit, actuation of the input points of the matrix is effected from the outputs of the explosive circuit, all similar inputs of the explosive circuit receive a detonation pulse at least from one of the group of electric detonators. Detonation pulses to all the second similar inputs of the explosive circuit are supplied from the second group of electric detonators with a diversification relative to the first inputs provided by the selection of the lengths of the detonation channels. Detonation pulses running from one or several electric detonators to the similar inputs of the explosive circuit are passed through the commutator of the detonation circuit. The detonators of the first and second groups are positioned in different points of the matrix with provision of a different degree of their screening from accidental actions, and the detonation channels between the electric detonators and the explosive circuit are so positioned that the diversification of passage of pulses from the electric detonators via the cross-section of the channels (except for the inputs of the explosive circuit) differs from the diversification of the "code" of the explosive circuit. ^ EFFECT: provided multiple-point initiation of the surface of the main explosive charge from one or more electric detonators for changing the from of the blast wave front, and prevented initiation of the explosive charge in case of an accidental blast of the electric detonator as a result of accidental actions (lighting discharge, shooting-through fire, etc.) ^ 2 dwg |
