Abstract：In order to effectively improve the safety quality of coal mine production personnel and reduce the occurrence of coal mine production accidents,this paper explores the problem of ignoring the seasonal varia-tion of the risk degree of coal mine events and the static measurement of safety quality in traditional research and constructs a dynamic measurement system of the safety quality of production personnel based on the sea-sonal variation of the risk degree of coal mine events.By analyzing the seasonal variation of coal mine event risk,drawing on the results of the academic community,conducting questionnaire surveys,and conducting ex-pert assessments,we constructed a comprehensive evaluation index and system for the safety quality of coal mine production personnel.Using the expert fuzzy set-value statistics method,combined with the seasonal changes in coal mine incident risk,the safety quality evaluation indexes are assigned dynamic weights by sea-sonal time,thus realizing a dynamic and comprehensive evaluation of the safety quality of coal mine personnel based on the dynamic weight assignment system at different seasonal times.The empirical study shows that based on the changes in the coal mine production environment,according to the seasonal changes of coal mine risk events,by dynamically adjusting the evaluation weight structure and conducting a dynamic comprehen-sive evaluation of the safety quality of coal mine production personnel by seasonal time,it is able to effectively excavate the deficiencies of the safety quality of production personnel in each seasonal time,and then target-ing to guide the coal mines to improve the safety quality of the personnel by seasonal time.This method is ex-pected to significantly improve the safety level of coal mines and reduce the occurrence of safety accidents,which has scientific and practical application value.
