Abstract

Butani, S.J., 1988. Relative risk analysis of injuries in coal mining by age and experience at present company. Journal of Occupational Accidents, 10: 209-216.In 1986, the U.S. Bureau of Mines conducted a probability sample survey to measure the characteristics of the U.S. mining industry workforce. This paper shows how demographics survey data are utilized to ascertain whether the observed variations in the injury (includes illness and fatality) risk for the coal mining industry in 1986 correlate with age or with experience at present company, or both.This analysis found that injuries in the coal industry vary more by experience at present company than by age. That is, the workers were experiencing injuries at the same rate when grouped by worker's age, but not when grouped by worker's experience at present company. Employees with 1 year or less experience were at a considerably higher-than-average risk, while employees with more than 15 years experience were at a lower-than-average risk. This was true for each age group as well as for all age groups combined.
