Using the Fisher Discrimination Analysis Theory (FDA), and according to the analysis results of the water sample, the authors establish the mathematical recognition model of the source of water burst in the Jiaozuo mining area and do its discriminatory analysis and result verification. The result shows that the result of FDA predicated water bursting source agrees with that of the chemical methods analysis of normal water; Ordovician groundwater recharges limestone in a re-markable way; the connection between sandstone water of the seam roof and deep karst water is weak; the FDA model is very powerful in identifying the source of water burst; by using back substitution estimation method, the error decreases continuously and it is of great applicability, easy to handle.
