Abstract:In order to maximize the benefits of comprehensive utilization of mine drainage, based on the calculation of available goaf water supply and water quality analysis of Wucun Mine, a mathematical model for optimal allocation of 718 m³/h goaf water quality utilization was established, and the differential evolution algorithm was used to solve the model. The results show that when drinking water is 5.70 m³/h, power plant water is 374.74 m³/h, irrigation water is 321.86 m³/h, aquaculture water is 12.84 m³/h and ecological water is 2.86 m³/h, the utilization efficiency of goaf water quality is the highest. The research results will provide a reference model for similar mine goaf water and mine drainage resource utilization.
