Study on the crack propagation morphology and initiation law of coal rock under the action of underwater electric pulse by XianKai Bao, Bin Jiang, GuangQin Cui, XiaoFan Zhang, Tong Zhang, Wu Zhang

“…Abstract Based on the symmetric initiation mechanism of double-wing cracks in coal rock mass induced by high-pressure electro-recoil water pressure, fracturing experiments have been performed on coal rock mass under different water pressures and discharge conditions using high-voltage electric pulse hydraulic fracturing devices. Combined with CT scans, the crack spatial distribution inside the post-break coal rock mass was analyzed and found that the edge of the water injection hole is prone to produce double-wing cracks along the drilling hole diameter. …”
