Water inrush is a frequent geological disaster and seriously threatens the production safety in coal mines. In order to discriminate the source of the water inrush quickly and accurately,42 groundwater samples of rare earth elements were collected in the Quaternary fourth aquifer,the coal and sandstone cranny aquifer,the Carboniferous Taiyuan formation karst aquifer and the Ordovician karst aquifer from the hydrogeological boreholes,underground drainage boreholes and groundwaterinrush sites. The hydro-geochemical characteristics of rare earth elements were researched by factor analysis. Two factors whose eigenvalues are greater than 1 were selected,and their 93. 055% cumulative variance contribution rate can account for the water chemistry information of most aquifers in Su-Lin mining area. The Bayes model was established to discriminate the source of water inrush with93% discriminating accuracy rate. The research provides a new scientific basis for the discrimination of water-inrush source in the process of coal mining.
