Assessment of the Impact of Abandoned Mine Water on Groundwater Environment

The assessment of the impact abandoned mine water on underwater environment is critical for protecting and restoring groundwater environment. Taking coal mining area in west Zhangqiu District as engineering background comprehensively considering regional chemical characteristics data during wet dry seasons, main ions, hydrochemical types, ion correlations with components were analyzed using mathematical statistics, correlation analysis, Piper diagrams. An was conducted quality index values monitoring point. Furthermore, this research establishes an evaluation method a based improved Nemero matter element theory. Overall, pH weakly alkaline District. Ca2+ dominant cation, while HCO3− SO42− are anions. concentration season slightly greater than season. type seasons HCO3-Ca. In addition, there between NO3− F−, which may be caused by human activities. classified level IV severely polluted.
