Electrical Rock Breaking

  title={Electrical Rock Breaking},
  author={R. S. Segsworth and Karl Kuhn},
  journal={IEEE Transactions on Industry Applications},
A technique has been developed for rock breaking which could be considered as an alternative to drilling and blasting. A series of tests and measurements involving initial dielectric breakdown achieved with high frequency power, followed by highly localized heating achieved by capacitor discharge energy is described. This heating causes relatively… CONTINUE READING
