Holmes Saf Assn Bull 1993 Jan; :9-12
Roof fall accidents are the leading cause of fatalities in the underground coal mining industry. Given that roof bolter operators play such an important part in preventing roof fall accidents, it is both ironic and tragic that ground falls kill more roof bolter operators than any other type of mine worker. Of the 87 coal miners killed by falls of roof and rib during the 5-year period 1987-91, 27 were roof bolter operators. Accident investigations indicate that approximately half of all roof fall fatalities occur inby supports. Given these statistics, and the fact that roof bolter operators perform much of their work in close proximity to unsupported roof, it seems especially important to know what might cause bolter operators to go inby supports. In order to better determine what might cause roof bolter operators to go under unsupported roof, Bureau of Mines researchers recently asked 78 roof bolter operators the following question: Considering the different tasks involved in doing the roof bolter operator's job, which ones are most likely to cause them to go under unsupported roof? Whenever a task was identified the roof bolter operator was also asked, What could be done to make it less likely that roof bolter operators would go under unsupported roof while performing that task? Some of the most frequently mentioned tasks and countermeasures are discussed in this paper.
