Development of fracturing technique employing the shock force by electric discharge method -Fracturing system employing electric-discharge shock force and fracturing performance-

摘要

When capacitor energy charged at a high voltage is provided with a metallic wire in liquid, a shock force is generated by the sudden melting and evaporation of the wire and the liquid. This paper describes the outline of the "ESG-10K 4" type electric discharge shock force generator and the fracturing system used in this method, the specifications of this system and the applicability of this method to concrete, rock and rock mass.
