An overview of the plasma rock fragmentation system, the first commercial application of plasma blasting, is presented. Plasma blasting is based on the fast delivery of stored electrical energy to fracture the rock. The capacitor bank, switching device, cable and blasting electrode employed in the system are described. Utilization of the chemical energy delivered from the electrolyte and the development of a large charge transfer switch using pseudospark enabled the commerciailzaion. The vibration and noise level of the blasting is acceptable in the most ground breaking.
