Abstract: To improve the scientificity and reliability of the evaluation results of safety control capabilities in mining en terprises,a comprehensive decision-making model for safety control capabilities in mining enterprises based on improved GRA TOPSIS is proposed.Firstly,an evaluation system was constructed by screening 13 influencing factors from four dimensions: safety management,employee safety level,risk prevention and control,and digitalization level. Secondly,using IAHP-SPA method to accurately process interval weights and obtain accurate weight information.Considering the fuzziness of indicator e valuation data,blind number theory is introduced,interval assignment is adopted,and indicator scoring is reasonably deter mined by establishing a blind number matrix.The GRA-TOPSIS model is comprehensively adopted to evaluate safety control capabilities.Finally,taking five mines as examples,based on the improved GRA-TOPSIS model,the safety control capabilities were ranked and the safety level was determined.The differences in safety control capabilities among mining enterprises were studied using radar chart analysis,and targeted improvement suggestions were proposed.The results show that improving GRA TOPSIS model has strong applicability in the evaluation of safety control capabilities in mining enterprises,and can provide the oretical support for improving safety management level.
