FIELD: mining.
SUBSTANCE: electrodischarge destruction method of solid materials involves formation of a bore pit in solid material, arrangement in it of a cartridge containing a substance that transmits an air blast and a blasting conductor, and initiation of a discharge with the blasting conductor. Cartridges are made from plastic material with acoustic stiffness close to acoustic stiffness of destructible material. Blasting conductor is pressed into cartridge material. Polyethylene or plasticine is used as plastic material.
EFFECT: improving destruction efficiency of mine rock and utilisation of concrete and reinforced-concrete units and structures.
