In this paper, based on consulting foreign and domestic literatures which are involved in research status of water source identification and analyzing geological data related to Pan′er coal mine, aquifers of water bursting in Pan′er coal mine is taken as the research object, and some conditions are analyzed including the hydrogeology condition and geological conditions of the mine field , hydrogeochemical characteristics of the main aquifers of water bursting in Pan′er coal mine. the analysis results show that the different components from water bursting are different ,but hydrochemistry types are similar，indicated that there is a certain degree of hydraulic relations among different bursting water souces. Six ions are taked as the research index, and the identified model of inrush-water sources is formed by fuzzy mathematics method and stepwise discrimination method,which has a better effect on distinguishing sources of inrush-water by the identified way.
