Abstract

The test data are reported on rock cutting by the electric discharge with movable and stationary electrodes. The specific crushing energy is determined, the electrode system design is optimized, and the high-voltage impulse parameters selected for highly efficient fracture. The study results make the grounds to develop an electric-discharge cutter for rocks and concrete.
