Outline
To explore the hydrochemical characteristics and hydraulic connections of different aquifers in the northern mining area of the Zhungeer Coalfield, and to reveal the regional water circulation patterns under coal mining activities, a total of 39water samples were collected from different aquifers in the mining area. The hydrochemical characteristics, controlling factors, and hydraulic connection degrees were analyzed using methods such as Piper trilinear diagrams, Gibbs diagrams, ion ratio analysis, chloride-alkalinity index, factor analysis, and connectivity index. The results show that the water in the mining area is generally weakly alkaline. The main hydrochemical type of the Quaternary and Shiqianfeng Formation aquifers is HCO--Ca type water, which is mainly influenced by silicate weathering and mining activities, with positive cation exchange occurring. The main hydrochemical type of the Zhidan Group aquifer is HCO3-Ca type water, followed by HCO3-Na and Cl-Ca types. Its sources are mainly influenced by the weathering dissolution of silicate rock minerals and the impacts of mining and agricultural activities, with positive cation exchange occurring. The main hydrochemical type of mine water is Cl-Ca type water, which is influenced by the weathering dissolution of silicate and evaporite minerals and mining activities, with reverse cation exchange occurring. The hydraulic connectivity indices between the Quaternary aquifer and the Zhidan Formation, and between the Zhidan Formation aquifer and the Shiqianfeng Formation are 27% and 20%, respectively, indicating the presence of hydraulic connections. The hydraulic connectivity index between the Shiqianfeng Formation aquifer and the mine water is 39%, indicating a weak hydraulic connection.
