The purpose of this article is to demonstrate the method and value of microanalysis through its application to reported personal injuries to roof bolters. The technique involves analysis of accident narratives in order to classify the reported injuries according to where they occurred in the roof bolter's work cycle. Microanalysis allows an investigator to use the narrative descriptions to frame the conditions and situations under which miners were injured, results which then may be used in annual refresher training to make breakout sessions site and job specific. A combination of microanalysis and work-site observations of roof bolters was used in this study to classify accidents into selected work routines, to calculate new accident indices, to characterize the situations and conditions surrounding the accidents, and to describe the causes of many of the accidents in work-related terms.
