Grayson, R.L.

The elevated fatality rates and, at times, the elevated serious injury rates in small mines (fewer than 50 employees but more than 19) and very small mines (less than 20 employees) have been documented in past studies (National Academy of Sciences, 1983; Tisdale, 1993; Peters and Fotta, 1994; Grayson, 1999). This paper presents a followup study of the 1996 West Virginia underground coal mine accident experience, extending it to all US underground coal mines with a focus on examining differences in both safety and productivity performances by mine size.
