Nov 14, 2022In practice, coal mining and geological conditions often disturb rock strata. Consequently, the surface water and rock stratum water penetrate the goaf along the rock fractures, causing residual coal in the goaf to be soaked in mine water for an extended period [9,10]. In the case of water infiltration during rock formation, a series of complex
