Abstract
In this project, a biomechanical and work physiology study of underground mines (excluding low coal) was conducted to generate data to be utilized in equipment and job design. Anthropometric, strength, physical work capacity, and nutritional intake measurements were collected on miners. Energy expenditure and postural data were collected on mining tasks to identify those tasks that were demanding. Male underground miners were not significantly different from comparison populations in terms of anthropometric characteristics, but they were significantly stronger. Females were heavier and larger in terms of circumferential measurements than comparison populations and were stronger. Both males and females were generally rated low in terms of aerobic capacity, and their nutritional intake did not appear to be adequate in terms of daily energy expenditure or recommended dietary allowances. Daily energy expenditures for mining jobs appeared to be reasonable in terms of percentage aerobic capacity, but this was due largely to travel and down time. Several mining tasks imposed stressful postures on miners. Recommendations based on the data collected are made.
