Abstract: In order to quantitatively evaluate emergency rescue capability of coal mines and clarify shortcomings of coal mines in the process of emergency rescue capability construction, a coal mine emergency rescue capability maturity evaluation model was proposed. Firstly, definition of coal mine emergency rescue capability was defined, and evaluation index system was constructed according to three stages: before, during and after the event. Secondly, maturity grade suitable for evaluation of coal mine emergency rescue capability was divided, and specific scoring standards were listed, and improved catastrophe progression method was introduced to calculate the total score of coal mine emergency rescue capability maturity. Finally, model was applied to quantitative evaluation of emergency rescue capability maturity level of a coal mine, and initial evaluation result was revised, emergency rescue capability maturity level of mine was obtained as an optimized level. The result shows that results obtained by model are consistent with actual conditions of coal mine, which verifies feasibility and effectiveness of model.

Key words: coal mine, emergency rescue capability, capability maturity model(CMM), evaluation model, catastrophe progression method
