High-level electrical energy can be suitably converted to shock waves of stress that, in turn, may be used for disintegrating hard rocks. This development, known as the electrohydrodynamic method, is very safe and highly economical compared to other methods of rock breaking. This paper deals mainly with development of the equipment and some details of the experimental work carried out with different rocks and concrete block.
