Abstract：To address the issues such as the insufficient integration of current discrimination methods with actual mine water source databases，a constant ion database for mine water inrush sources was developed for Pingmei No.5 Mine using a combined Piper trilinear diagram，boxplot，and cluster analysis method，Additionally，based on Partial Least Squares Determinant Analysis （PLS-DA），a comprehensive prediction and discrimination technique for mine water inrush sources was proposed. Then，a MATLABbased software system was developed to quickly and accurately identify underground water sources.34 water samples from underground aquifers were selected as training samples ，among which 6 water samples were selected as testing samples，and the model was applied in working face of Pingmei No.5 coal mine.The results indicate that： The cumulative explanatory power of the model R2X（cum） reaches 99.96%，and the cross validation cumulative predictive power Q2（cum） is 73.7% The model accurately predicts the classification of sandstone water，Taihui water，and Cambrian water，The inrush water from the gob area is consistent with field observations.This study offers theoretical support for grout reinforcement and mining progress design in underground operations，providing a new quantitative approach for rapid and precise mine water inrush source identification.

Key words： water inrush source discrimination; water source database; PLS-DA algorithm; training samples
