In order to protect the psychological health of heavy-haul locomotive crew and explore the level of psychological health and influencing factors of heavy-haul locomotive crew,a sampling survey was conducted on the health and performance data of locomotive crew. First,the psychological health characteristics corresponding to safety performance were extracted,and psychological standards for the crew were developed. Then,the characteristics of the sampling objects were collected and counted,and influencing factors were analyzed. The results show that the safety attitude and safety thinking of heavy-haul locomotive crew are significantly higher than those of other job groups. At the same time,the psychological state of the heavy-haul locomotive crew is positively correlated with their level of education and negatively correlated with their sleep quality. Meanwhile,conducting psychological state assessments for the heavy-haul locomotive crew is helpful for normalizing psychological health monitoring. By constructing a full-cycle psychological health indicator for key positions,a new method for evaluating the psychological health of heavy-haul locomotive crew is developed,and it can serve as a reference for other industrial and mining enterprises to evaluate the psychological health of key position groups.
