IDENTIFICATION MODEL OF GUSHING WATER SOURCES IN PINGDINGSHAN COAL MINES

The samples of groundwater chemistry collected at Pingdingshan Coal Mine were analyzed geostatistically to identify from which apuifer(s) the water originate(s),and to set up an identification model of gushing water sources.Taking six major ions of groundwater as variables,the cluster analysis and Piper diagram analysis were done for 37 water samples.Based on the results of the two methods above mentioned,the discriminative analysis was used to obtain the identification model of gushing water sources,and the model is proved to be effective through F test and "attribution probability" test.
