Abstract：Objectives In order to evaluate the safety situation of coal mines reasonably and effectively,Methods the evaluation method of the variable weight-cloud model was proposed by combining the weight-ing method and the variable weight synthesis method.According to the three-year action evaluation table of Henan coal mine safety special rectification and field investigation,24 evaluation indexes were selected from four aspects:personnel,equipment,environment,and management,and the evaluation index system of coal mine safety production was established.The coefficient of variation method was used to improve the de-termination of the importance of indicators in the G1 method,and the evaluation indicators were combined with the COWA objective weighting method.Through the variable weight synthesis method,the constant was modified,and the cloud map of safety production evaluation was drawn in combination with cloud model theory.Results The results showed that the evaluation results of the proposed evaluation method of variable weight-cloud model were consistent with the field investigation evaluation results,which verified the accu-racy of the evaluation method.The selection of evaluation indicators and the classification of risk levels were reasonable,and the variable weight synthesis method could better realize the dynamic weight calculation.The evaluation method of variable weight-cloud model combined with the cloud model theory could realize the qualitative and quantitative analysis of evaluation indicators,and the drawn cloud map could represent the fuzziness and randomness of the evaluation results,which could well evaluate the safety production of coal mines.The rationality of the selection of evaluation indicators and the accuracy of the variable weight-cloud model evaluation method were verified,and the shortcomings of the current safety work in the coal mine were pointed out.Conclusions The constructed evaluation index system and evaluation model could be applied to coal mine safety production evaluation and provide guidance and reference for further strength-ening coal mine safety production work.
