Summary

Rock breaking is crucial in mining and drilling, with high-voltage pulsed fragmentation (HVPF) showing great efficiency and potential. HVPF has lower energy consumption and higher advance speed than mechanical drilling in hard rocks. The technique involves electric discharge producing strong power, fragmenting rock through mechanical forces or direct breakdown. Researchers modeled electrical fragmentation using an electro-hydro-thermo-mechanical approach, identifying coupling between physics and optimizing conditions for industrial implementation. Direct electro pulse rock breaking is more efficient, with a higher crushing efficiency, and involves the formation of conductive channels and energy release to break down the rock sample.
