Analysis on groundwater resource in Feicheng mining area

In order to correctly understand existing problems in water resource development and utilization,the groundwater resource,in Feicheng mining area,is analyzed scientifically by examining the transformation of dynamical and chemical condition in groundwater.The research results indicate that the quantity of atmosphere precipitation in Feicheng basin has an immediate effect on the water table in the coming year,the content of fluorin ion in groundwater from the fourth and fifth limestone is generally higher;the Quaternary pore water suffered from the pollution of nitrogen at large and the content of nitrate is relatively high,at the same time the Ordovician aquifers contain higher nitrate component;the rigidity and mineralization degree in surface water and mine hole water are over the standards,and the large sulfur acid radical concurrence in the water.The research also shows after sedimentation and wiping off suspending substance,mine water will achieve sewage integrative letting standard,sight using water quality standard, and coal mine dustproof water using standard;the clustering analysis and gene analysis show the fifth limestone groundwater has consanguineous waterpower relation with the groundwater of Ordovician limestone.
