FIELD: coal and oil industries, hydraulic, highway, irrigation engineering, etc. SUBSTANCE: the method consists in the fact that electromotive force is induced in each section of the electric explosion network containing electric detonators from a variable AF magnetic field radiator, which is alternately contactlessly approached to each electric detonator, and electric current is recorded at the input ends of the electric explosion network by a magnetic signal recorder. EFFECT: enhanced quality of check-up of parallel and composite networks.
