For the accuracy of the inrush risk assessment of the problem, put forward in the mine inrush risk assessment using the entropy weight fuzzy comprehensive evaluation method to determine the index weight, through the membership function in fuzzy comprehensive evaluation to quantify the qualitative description of these factors, evaluated the henan jiaozuo mine inrush risk. The results show that the mine water inrush risk grade is "great", the actual mine water inrush accidents have occurred, prediction results conform to the actual situation, and safety evaluation value based on the principle of maximum membership degree is more than analytic hierarchy - fuzzy comprehensive evaluation to get , 0.0696. Thus, the method in the mine inrush prediction can objectively and accurately reflect the actual situation of mine inrush.

First, the index system is established for coal mine safety evaluation according to the influencing factors of coal mine safety. Then, weights of mine safety estimation factor is determined by using Analytic Hierarchy Process(AHP).Last,mathematical model of fuzzy comprehensive evaluation is set up for coal mine based on fuzzy theory and used to safety evaluation of a state-owned coalmine . The researched index system is feasible and effective; weights of mine safety estimation factor are responsed through this index system which can be used widely in the coal mine safety evaluation and administrative decision.
