Abstract: In the article the PDCA-CMEC (Coal Mine Emergency Capability) building model was put forward considering the continuous improvement of emergency capability building. According to this model, the assessment index system of emergency capability in coal mine enterprises which included 4 first-level indications and 18 second-level indications was established based on the coal mine emergency planning capability, emergency execution capability, emergency checking capability and emergency response capability. Then, using analytic network process (ANP), the interdependence and feedback relationships between the indexes were analyzed and the ANP-CMEC (Coal Mine Emergency Capability) structure model of coal mine emergency capability was build. The super matrix was also analyzed and the index weight was calculated using SD (Super Decisions) software.
