Abstract: Twenty water samples were collected in Huaibei coalfield, China in July, 2014, and major ions and isotopes of hydrogen and oxygen contents in water samples were tested; Water type, hydrochemistry process and applicability of the water samples were also discussed. Based on multivariate statistical analysis and traditional graphic methods, results show that water samples present weak alkaline, with high TDS concentrations. The water samples are mainly Na-SO4 and Na-HCO3 type, with high concentrations of Na++K+ and SO42-+HCO3- in anions and cations, respectively. The water samples are suitable for irrigation, whereas are not suitable for drinking before treatment. The σD and σ18O are varied from -53.07‰ to -22.07‰ and -6.97‰ to -1.23‰, with average value -38.30‰ and -4.09‰, respectively. The formula between σD and σ18O (σD=5.32σ18O-16.54) is clear affected by evaporation, what could be as reference for regional evaporation line. Elements contents in water samples were mainly influenced by rock weathering and evaporation, according to the analysis of Gibbs and principal component.
