Relationship between work place and worker characteristics and severity of injuries in US underground bituminous coal mines, 1975-1981
Data were obtained from the accident and injury files compiled by the Health and Safety Analysis Center (HSAC) of the Mine Safety and Health Administration (MSHA), Department of Labor. Analyses were conducted on 83,297 underground bituminous coal-mining injuries. The findings were of two types: variates that showed a distinct relationship with the criterion variables; and those which were significant because they did not show any relationship with the criterion variables. Of the former, supervisory and maintenance personnel were found to have fewer chances of severe injuries than other job classifications. The shaft/slope location was less likely to be the site of severe injuries than the face area. In addition, when an injury occurred, the probability of it being a serious one was found to be greater for each succeeding year studied. The following variates showed no relationship with the criterion variables. Mining method was found unrelated to injury severity. Older miners had the same probability of serious injuries as younger miners. No relationship was found between the three experience variates and the measures of severity. Mobile equipment operators had the same chance of severe injuries as other job classifications. The intersection and other locations had the same likelihood as the face of serious injuries. Finally, there was no relationship between time elapsed before an injury and the measures of severity.
