In this study; a total of 50 groundwater samples from the coal-bearing aquifer in the Xinji coalfield (one sub-coalfield of the Huainan coalfield) have been collected; and their major ion concentrations have been measured for the evaluation of its suitability for drinking and irrigation; and then the mechanism controlling the water chemistry have been analysed. The results indicate that the groundwater samples are slightly alkaline with TDS higher than the freshwater (- and HCO3- types. The groundwater samples have WQI range from 5.63 to 179 (mean = 64.9); suggesting that these samples are good for drinking. However; the results of sodium adsorption ratio and residual sodium carbonate indicate that only a few of the samples can meet the requirement of irrigation; but must be treated before application. Gibbs diagram and the relationships between major ions; as well as the factor analysis; imply that water-rock interaction is the main process controlling the groundwater chemistry; including the dissolution of evaporate minerals and the weathering of silicate minerals. © 2020 Technoscience Publications.
