Method for rock fracture and crack propagation by high voltage shock wave

摘要

The present invention relates to a rock fracture and crack propagation method using a high-voltage shock wave which excludes the use of explosives and minimizes noise and vibration by applying a high-voltage shock wave in a state where water is filled in a blast hole, A rock breaking and crack propagation method using a high voltage shock wave according to the present invention includes applying a high voltage to water in a rock blast hole in a state where water is filled in a rock blasting hole; A high voltage shock wave is generated due to the application of a high voltage and a strong pressure wave is generated and the water in the rock blast hole is expanded by the pressure wave and crushing and crack propagation of the rock mass is caused by the swollen water .
