摘要： An electric discharge breaking system (61) comprising a container (62) fitted in a hole (73) formed in an object (72) to be fractured. The container (62) contains a thin metal wire (64) connected between a pair of electrodes (63) and charged with a breaking substance (71). There are breaking openings formed in a side wall of the container (62) so as for leading outward in prescribed directions an expansion force generated by fusing and vaporizing the breaking substance (71).
A method for manufacturing the discharge system (61) uses a fluidized self-hardening substance (71) as the breaking substance which is charged into the container (62) after the breaking openings are closed with a sheath member (75) that is peeled off after the self-hardening substance (71) is solidified.
The discharge breaking system (61) and the manufacturing method therefore permit carrying out discharge breaking works with high efficiencies since expansion forces are led to the breaking openings formed in the containers (62).

摘要： A discharge destroying device and a method of discharge destroy used for destroying the bedrock of a formed housing site, crushing rocks and stones, trimming a tunnel, and destroying and demolishing and object such as a concrete structure. The discharge destroying device (1) is such that electric energy which is accumulated in a capacitor (13) is fed between a pair of electrodes (4a) in a short period of time, discharge is caused, a destroying substance (3) for pressure transmission is rapidly vaporized, and an object (H1) is destroyed by the expansion forces generated at this time. The ends of covering members (7), which cover a pair of metal conductors (4) forming a cable (6), is cut and removed, the exposed ends of the metal conductors (4) are immersed in the destroying substance (3), and the exposed ends are used as the electrodes (4a). Adjustment of the distance between the electrodes (4a) is not needed, and the manufacture of the discharge destroying device is easy.

摘要： A blasting method which comprises delivering electrical energy at a rate of at least 100 megawatts per microsecond until a peak power of at least 3 gigawatts is reached across the gap of two poles of a coaxial electrode assembly immersed in an electrolyte within a confined area of a substance to be blasted. A dielectric break-down of the electrolyte in the confined area is produced resulting in the formation of plasma within the confined area which creates a pressure sufficient to blast the substance in the manner of a high explosive charge.
