Abstract
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 nonviolent shattering of the rock.
