Evaluation of Coal Mine Emergency Management Ability Based on Entropy Weight Method and BP Neural Network
Objective To further improve the safety emergency management ability of coal mining.Method The evaluation in-dex system,which includes 4 first-level indexes and 16 second-level indexes,including prevention,rescue,guarantee and recovery of emergency management ability,was constructed by consulting relevant literature and soliciting the opinions of experts.Secondly,entropy weight method is used to determine the weights of all levels of indicators,and BP neural network is combined to establish a comprehensive evaluation model of coal mine emergency management ability.Finally,the model is applied to a coal mine in Shanxi Province.Result The risk assessment and early warning of the accident,the rescue level of the rescue team,the construction of the emergency department and the site,the recovery plan after the accident,the loss and assessment of the accident,five factors have a great impact on the emergency management ability of a coal mine in Shanxi Province.Conclusion The evaluation result of safety emergency management ability is"good",which is consistent with the actual level of emergency management ability,and provides a theoretical basis for safety evaluation of a coal mine in Shanxi.
