Abstract：From the perspective of three kinds of hazards, namely, the inherent hazard, induced hazard and human factor, the complexity and variety of gas accidents were analyzed, the evaluation index system for gas hazards was built, and the indix weights were determined by the methods of analytic hierarchy process and gray correlation analysis. The G-F ( gray-fuzzy) comprehensive evaluation model for gas accidents which is based on the gray-fuzzy algorithm was established by combining the gray theory with fuzzy mathematics, evaluation was made on the hazard of a gas anomaly area in a mine, and the risk level of gas accident was determined. The practice showed that this model can give an accurate evaluation of the risk level of gas accidents and can further improve the evaluation and early warning of gas accidents.
