Effects of demography and occupational traits on consequence of injury of underground coal miners

In spite of introduction of modern underground mining methods, mining is still a hazardous occupation. Different individuals are exposed to different levels of injury risk and injury severity due to individual and workplace characteristics. In this paper, accident data of three Indian underground coal mines were collected. The analysis was done based on consequence of injury (in terms of man-days lost) with due emphasis on workers´ age, occupation, cause, skill and body parts injured. The relative risk of various contributing parameters was estimated using multinomial logistic regression analysis. The results reveal that age of the worker, skill of the worker and the cause of injury bear no significant relation on consequence of the injury. It is observed that the relative risk of occurrence is mine specific. The limbs are the most vulnerable parts of the body causing highest number of man-days lost.
