Discharge destroying method, discharge destroying device and method of manufacturing the same

A discharge breaking system comprising a pair of electrodes having a thin metal wire connected between ends thereof and inserted into a hole which is formed in an object to be fractured and charged with a breaking substance, a capacitor connected to said electrodes, a power supply unit for supplying electricity to said capacitor, a charging control circuit interposed in the course of charging electric wires between said power supply unit and said capacitor, and a discharging switch interposed in the course of discharging electric wires between said pair of electrodes and said capacitor, characterized in that

• said breaking substance to be charged in said hole is filled in and subsequently sealed by a fiber member impregnated with liquid in a container for accommodating said thin metal wire connected between lower ends of said electrodes, and
• said discharge breaking system further comprises a stopper tapped into said fiber member for closing an opening of said hole after said container is fitted in said hole during a discharge breaking work.

A discharge breaking system comprising a container fitted in a hole formed in an object to be fractured, said container being inserted with a thin metal wire connected between a pair of electrodes and charged with a breaking substance, a capacitor connected to said electrodes, a power supply unit for supplying electricity to said capacitor, a charging control circuit interposed in the course of charging electric wires between said power supply unit and said capacitor, and a discharging switch interposed in the course of discharging electric wires between said pair of electrodes and said capacitor, characterized in that

• breaking openings are formed in a side wall of said container so as for leading outward in prescribed directions an expansion force generated by fusing and vaporizing said breaking substance.

A method for manufacturing a discharge breaking system having a container fitted in a hole formed in an object to be fractured, the container having a thin metal wire connected between a pair of electrodes and charged with a breaking substance, a capacitor connected to the electrodes, a power supply unit for supplying electricity to the capacitor, a charging control circuit interposed in the course of charging electric wires between the power supply unit and the capacitor, a discharging switch interposed in the course of discharging electric wires between the pair of electrodes and the capacitor, and breaking openings formed in a side wall of the container so as for leading outward in prescribed directions an expansion force generated by fusing and vaporizing the breaking substance, comprising closing the breaking openings with a sheath member, charging fluidized self-hardening substance into the container, and peeling the sheath member off after the self-hardening substance is solidified.
