| 英文摘要 | This research aimed to investigate the changing mechanism of hydro-geochemistry in Ordovician limestone karst (OL) water induced by mountainous coal mining activities. Thus, the hydro-geochemistry evolution of OL water over 40 years within a typical northern mountainous coal mine named Fengfeng Mine was studied by using Piper diagram, Gibbs scheme, ions correlation and Principal component analysis (PCA ) methods. Results showed that, except for HCO3-, the ions of Ca2+, Mg2+, SO4(2-), Na++K+, Cl- and total dissolution solids (TDS) values all increased by years as mining continues. Different hydro-geochemical characteristics in different periods can reflect different water-rock interactions. Accordingly, sulfates dissolution gradually took place of carbonates in water-rock interaction. Especially, OL water-rock interactions in different periods were all affected by rock weathering and evaporation-concentration together. At last, evaporation-concentration co-effect dominated the hydro-geochemistry evolution slowly, along with significant cations exchange over years. |
