Firstly, taking the possibility and severity of dust explosion as the one class index, the distribution of personnel, the layout of buildings, the equipment and facilities and others as the secondary indicators and safety management measures as compensation index, the risk assessment index system of dust explosion was constructed. Secondly, the weights of each index were determined by combining the AHP and the entropy method, and the risk assessment model of dust explosion was established to evaluate and classify the risk of dust explosion. Finally, taking the dust explosion accident of an enterprise as an example, the application of the proposed risk assessment method was studied. The results show that the classification of the evaluation indexes directly affect the risk assessment results of dust explosion, that the safety compensation measures can effectively reduce the risk of dust explosion in enterprises, and that the risk grade of dust explosion in the enterprise is general by using this risk assessment method, which is consistent with the evaluation results of the expert team at national level. %U http://www.cssjj.com.cn/EN/10.16265/j.cnki.issn1003-3033.2019.07.026
