As one of the major methods for water disaster controlling, hydro-geochemistry had attracted a series of studies related to water source discrimination. In this paper, a simple method for constructing the water source discrimination model based on major ions and multivariate statistical analysis has been reported following the proce- dures: (1) collection of data and interpretation; (2) analysis of controlling factor based on the chemical composition of ground- water; (3) “pure” sample chosen and (4) discrimination model establishment. After the processes, two functions and a diagram have been established for three aquifers (the Quaternary, Coal bearing and Taiyuan Fm) from the Renlou coal mine in northern Anhui Province, China. The method can be applied in almost all of the coal mines and, can be used for evaluating the contribu- tion ratios if the water is collected from a mixing source.
