Abstract:

In order to study the chemical evolution mechanism of the underground water in the Jiaozuo mining district and ascertain the recharge sources of karst water to provide scientific evidence for the prevention of mine water bursting, water from the study areas is sampled. The piper diagram, lithology effects, the correlation matrices, TDS, and quantitative hydrogeochemical simulation technology are used to gain the hydrological geochemistry function in spatial distribution and evolution rules.  Mass balance reaction model of underground water is established to provide quantitative information of evolution mechanism about the chemical constituents of karst groundwater. It is discovered that the exchange of positive ions of Ca2+-Na +、Mg 2+-Na + efflorescence and lioxiviation evaporation and concentration, non-congruent dissolution of dolomite are the major hydrological and chemical process to control the formation and the evolution of the underground water,which provides a theoretical basis to infer the recharging sources of groundwater in the mining district.

Key words: groundwater, hydrochemical characteristic, hydrogeochemical modeling;formation mechanism, Jiaozuo mining district
