Workload is one of the reasons that affect unsafe behavior in coal mines. This article divides workload into six dimensions: physical demand, mental demand, time demand, performance level, effort level and frustration level, and introduces miner emotions as an intermediary variable to study the impact of workload on unsafe behavior. Through a questionnaire survey of coal mine workers, a structural equation model of coal mine workers’ workload and unsafe behavior is constructed. The results show that the six dimensions of workload have a significant impact on emotions. Physical demand, mental demand, time demand and frustration level have a significant impact on unsafe behaviors. Performance level and effort level have no significant impact on unsafe behaviors.
