Research on Evaluation of Coal Mine Emergency Plan based on Attribute Mathematical Theory

According to the actual situation of coal mine and the requirements of coal mine emergency plan evaluation, the evaluation system of coal mine emergency plan was established. Based on the interval recognition theory of attribute mathematics, the evaluation model of the evaluation system and the attribute recognition model of classification were established, and three subordinate indexes in secondary indicators of emergency organizations and responsibilities in the emergency plan were evaluated and analyzed. The attribute space matrix of mine emergency plan evaluation was given by determining the evaluation index and classification standard of mine emergency plan; Analytic Hierarchy Process(AHP) was used to calculate the weight of each discriminant index, and the attribute measure function was constructed to calculate the single attribute measure, which was transformed into the comprehensive attribute measure; attribute identification of emergency plan evaluation system was carried out by using confidence recognition criterion. The result of case analysis shows that the mathematical theory of attributes is feasible and effective for coal mine emergency plan evaluation.
