The results show that the concentration of Na + + K + , HCO 3 - , Cl - , SO 4 2- , TDS, and pH increase from the recharge area to the discharge area, however, that of Ca 2+ and Mg 2+ decreases.And each indicator varied greatly in the north and south of the coalfield. Hydrogeochemical types of the runoff from Zhuozishan Mountain to Gongdeer Mountain and then to the south-north directional change. And the groundwater process is controlled by rock weathering action and cation exchange. Whereas the hydrochemical type of the runoff from Zhuozishan Mountain to the south is always SO4▪Cl-Ca▪Na type Hydrology Characteristics of geochemistry groundwater Piper trilinear Figures Figure 1 Figure 2 Figure 3 Full Text Additional Declarations The authors declare no competing interests.
