Abstract:Theexisting mine safety evaluation methods adoptrelatively simple evaluation indicators and cannotquantitativelyanalyze theuncertainty degree ofvarious indicators,resulting in significant limitations in practical engineering applications.To addressthese problems,a comprehensive mine safety evaluation method based on entropy weight and set pair analysis method is proposed.First,a comprehensive mine safety evaluation index systemconsistingof19 indicators wasconstructed based onfour factors:human,machine,environment, and management.Then,the entropy weight method was used to automatically determine the weights according to thedegre ofdispersionofthesafety evaluationdata,whichcouldefectivelyavoid subjective interference while ensuringboth simplicityofcalculationandobjectivityandaccuracy.Finall,expert scoring wasusedto obtain the scores of each safety evaluation indicator,and set pair analysis method was applied to calculate the degree of connection between the indicator scoresand diferent risk levels.The weighted average method was further adopted to obtain the average connection degrebetween each evaluation object and diferent risk levels. Based on the maximum membership degree theory, the final mine safety risk level was determined. The application results showed that the calculated risk level of Xiaobaodang Mine using this method was low,which was consistent with the actual situation. The main unsafe factors of the mine were high worker fatigue rate during actual perations,low compliance rate of technical standards,slow equipment updates,and incomplete emergency management measures and untimely safety inspections. The method can provide a reference for improving mine safety in the future.

Key words: mine safety evaluation; entropy weight method; set pair analysis method; safety evaluation indicator; safety risk level
