Effect of pre-crack on coal and rock mass induced by high voltage electric pulse in water

In order to explore the influence of prefabricated cracks on coal rock mass induced by high voltage electric pulse in water, and improve the permeability of coal and rock strata in the mining area, the high voltage pulse cracking tests were carried out on similar samples of coal and rock mass with a...
