Abstract: Coal mining is bound to destroy natural hydrochemical environment. However, in the concealed coal field in North China, the hydrogeochemical characteristics of discharge aquifers under mining-induced disturbance has not been researched from view of space and time, and the true hydrochemical feature and spatio-temporal evolution mechanism could not be well revealed. For this reason, taking the Linhuan coal-mining district as study area, conventional ions and trace elements are studied by principal component analysis (PCA). The results show that ...
