Abstract:

To prevent occupational injuries of national mine rescuers, the epidemiological characteristics and risk factors of occupational injuries were investigated. Firstly, the injuries of the rescuers of the National Mine Emergency Rescue Team in Datong were investigated through field study, expert interviews, and questionnaire surveys. Then, a national mine rescuer injury causal model was proposed to determine the occupational injury risk factors. Finally, all risk factors were used in binary Logistic regression equation to determine the key risk factors. The results indicated that occupational injuries occurrence of the national mine rescuers was high (54.9%). Furthermore, training injuries (80.3%), pulling and picking force devices (29.1%), and weighted running (15.2%) were the most common training items for injuries. The waist (37.2%), knee joints (11.2%), hands (9.0%), and ankle joints (7.6%) were the most vulnerable body segments. Work-related injuries (28.7%), sprains (25.1%), and strains (22.4%) were the most common injury types.The major internal risk factors affecting occupational injuries of national mine rescuers were training years, and the external factors were drinking alcohol, weekly training frequency, training with injuries, and lack of sleep. The major inducing events for injuries were insufficiency warm-up, recurrence of old injuries, and incorrect technical movements.

Key words: national mine rescuers, occupational injury, risk factor, training with injury, lack of sleep
