This data is based on the basic hydrogeological data of the study area, and water samples were tested for hydrochemical ions and hydrogen oxygen isotopes. Mathematical statistics, Shukalev classification, Piper trilinear diagram, and Gibbs diagram were used to analyze the hydrochemical characteristics, types, main ion composition characteristics, sources, and influencing factors of different water bodies. Furthermore, the transformation methods of precipitation, surface water, groundwater, and mine water in different periods of the study area were analyzed, clarifying the process and influencing factors of precipitation surface water groundwater transformation in the basin. Environmental isotopes and multivariate mixing models were used to analyze the transformation relationship and intensity of different water bodies in the basin.
