Occurrence of coal mine water inrush accidents were mainly relevant to abnormal water inflow, exceeding water discharge capacity and invalid emergency reaction besed on analysis of using PHA method in accident reasons, which got elementary event of FTA, determined analysis content and laid a solid foundation of FTA. On the basis of various subjective and objective factors, fault tree model of water inrush accident was constructed. According to minimum cutset and path set got by Boolean algebra rule and importance analysis of structure, primary causes of coal mine water inrush accidents were summarized. Combination of PHA and FTA method was conducive to result accuracy, provided a new way to accident prevention and improved safety evaluation level of coal mine enterprises.
