Experimental Study on Lateral Permeability Evolution of Sandstone under Seepage-Damage Coupling by Dongdong Pang, Feisheng Feng, Guanghui Jiang, Dongjing Xu, Xiaohan Wang

“…In several stages, the sandstone lateral permeability experiment under the coupling effect of stress and seepage demonstrates that the permeability of the aquifer in the coal mining front is significantly reduced after the original rock stress is disturbed by mining, suggesting that the water inrush calculation of the traditional water-flowing fractured zone and caving zone aquifer rock permeability experiment is inaccurate. …”
