Abstract：In this paper,7 water samples of Ordovician limestone aquifer,6 water samples of L1 -4 limestone aquifer,25 water samples of L7 -8 limestone aquifer and 7 water samples of other aquifers were collected for the study from ZhaojiaZhai Coalmine.The results show that the water types of different aquifers were different in a certain degree,for example,the L7 -8 limestone water type is HCO3 -SO4.Choosing 6 ions as discriminant factors,grey relational grade analysis,discriminant analysis and BP neural network were used to distinguish the water sources.Then,the method of BP neural network was selected out to be the best suitable mathemati-cal discrimination method.
