Study on the Vulnerability of Coal Mine Emergency Management based on ANP and Multi-level Extension

To comprehensively and systematically evaluate the vulnerability of coal mine emergency management system,firstly,the vulnerability assessment indexes system consisting of four guidelines and twenty specific indexes was constructed;because of the mutual dependence and mutual influence of each indicator factor,the analytic network process (ANP) was introduced to construct the judgment matrix to determine the weight.Secondly,the vulnerability was classified,the classic domain and section domain of vulnerability evaluation of coal mine emergency management system were established,the correlation function between the evaluation index and vulnerability level was constructed.Finally,the vulnerability grade of mine emergency management system was determined by taking into account the influence of each index weight and the multi-level extension evaluation method.The evaluation model was used to evaluate the vulnerability of emergency management system of Hejiata Coal Mine in Shaanxi.The result shows that the model is feasible and effective.
