Research progress on work-related musculoskeletal disorders of coal miners / 中国职业医学

ABSTRACT

Coal miners are a high-risk occupational group of work-related musculoskeletal disorders(WMSDs). This disease not only causes a reduction in the quality of life of workers, loss work ability, and decline in work efficiency, but also becomes an important factor leading to increase social medical burden. At present, most of the evaluation of WMSDs of coal miners at home and abroad adopts the international general scale. Chinese scholars have developed a WMSDs questionnaire that meets the occupational characteristics of Chinese population based on the international general scale—the Chinese Musculoskeletal Disorders Questionnaire. The questionnaire has good reliability and validity, and is a reliable and effective tool for evaluating WMSDs. The prevalence of WMSDs in coal miners is relatively high. The occupational factors that affect WMSDs in coal miners are mainly physical load, postural load, mental load, work organization, and work environment. The individual factors are mainly age, working experience, and education level. It′s recommended to prevent and control the occurrence of coal miners′ WMSDs through multi-level intervention measures such as strengthening education, changing the working posture, and improving the working conditions of coal miners, and rationally arranging labor organizations.
