智能化背景下矿工风险感知水平对不安全行为产生的影响OA北大核心CSTPCD

To fully explore the impact of miners'risk perception level on unsafe behavior in the context of intelligentization,firstly,the changes in miners'work content and risk perception in the context of intelligentization were analyzed.Secondly,based on the entire process of individual receiving,judging and generating information,four factors of individual factors,operational factors,management factors and organizational factors were proposed as the index system of miners'risk perception level in intelli-gent coal mines.An unsafe behavior simulation model based on system dynamics was established.Then,the weight coefficients of each indicator were determined by using the G1 method and the C-OWA operator.Finally,the simulation of intervention strategies was carried out to dynamically analyze the interactions between various indicators.The results show that among the influencing factors,the pri-mary index of individual factors(0.325)has the highest weight,and the secondary indicators of safety awareness(0.087 4),safety atmosphere(0.077 5),safety supervision(0.077 4),safety investment(0.064 4),and safety knowledge(0.064 3)have relatively large weights.In the context of intelligenti-zation,there are 108 action paths through which miners'risk perception level affects unsafe behavior,and 3 action paths have relatively large weights.The combination intervention strategy of improving safety systems and enhancing intelligentized training has significant effects on improving miners'risk perception level and reducing unsafe behavior levels.The research results can provide a basis for intelli-gent coal mines to improve miners'risk perception level and reduce the occurrence of unsafe behavior.
