Abstract: In order to solve the problems of subjectivity and fuzziness in the evaluation of mine gas explosion emergency rescue capability in China, Firstly, a total of 29 discriminant indexes were selected from 6 aspects, including mine ventilation system management, mine gas accumulation prevention ability, emergency rescue technical support, emergency rescue organization support, emergency rescue equipment support, and mine rescue and recovery ability to construct the evaluation index system of mine gas explosion emergency rescue ability. Secondly, the introduction of the unascertained measure theory and game theory set pair theory construction of mine gas explosion emergency rescue capability level evaluation and sorting model, using the straight-line method of unascertained measure single index structure function, the technology based on game theory combination determine the index weight, according to the degree of confidence recognition criteria to determine level of evaluation and sorting; Finally, the model is applied to the comprehensive evaluation of the emergency rescue capability of a high gas coal mine. The results show that the evaluation level of the coal mine's emergency rescue capability is good, but it still needs to take further effective control measures. The model has high applicability and operability, and can objectively and accurately evaluate the comprehensive evaluation of the coal mine's emergency rescue capability of gas explosion.
