Breakage of rocks by pulsed electric discharge at elevated pressures and temperatures

Abstract

The process of electric-pulse-induced breakage of sandstone, limestone, and granite at elevated pressures (up to 350 atm) and temperatures (up to 110°C) has been studied. The dependences of the material fracture depth, breakage output, and specific energy consumption on the temperature and pressure are determined.
