Abstract: As an important content of coal mine emergency management, through emergency capability evaluation, coal enterprises can locate their capability level in response to the accidents and find themselves problems in emergency management. Based on the review of the previous research on coal mine emergency management evaluation capability, the article determined the appropriate index system and calculated each index's weight with AHP based on the idea of emergency response capability evaluation index system. Then the classical field of matter-element model for emergency capability and its controlled field are constructed with the application of extension superiority evaluation method. Taking a certain coal mine in Shanxi province as an example, through the calculation of evaluation matter-element superiority, it gives an evaluation level for the certain coal mine's emergency capability, which can give guidance for coal mines to upgrade their emergency capability.
