METHOD FOR ELECTRIC BURSTING OF EXTENDED EXPLOSIVE CHARGES Russian patent published in 2005 - IPC

FIELD: blasting operation.

SUBSTANCE: in the method for electric bursting of n extended explosive charge along the line of its layout conversion of the electric energy partially to the thermal and kinetic energy is realized with the aid of two parallel wires connected to a high-voltage source so that one end of the first wire would serve as a positive terminal, and the opposite end of the second wire would serve as a negative terminal of two wires moving toward each other producing eventually a shock-wave initiation of the primary charge of explosive material along the line of their layout providing a good synchronism of formation of the detonation front in an extended explosive charge.

EFFECT: reduced time difference down to 1µs of blasting of an extended explosive charge at lengths within 0.1 to 0.5 m.
