The Bureau of Mines has been actively involved in a study of worker safety on longwall operations during an underground mine fire. The results of this investigation were twofold. First, those factors affecting worker survival during a mine fire were defined and second, any relationships between these factors were identified. Although the individual factors affecting worker safety had been studied before, little information was available on their interdependence. Fault tree analysis was used to evaluate the miner escape scenario. A fault tree was constructed to analyze the occurrence of fatalities during an escape from an underground mine fire. The completed fault tree contained 24 initiating events. After constructing the fault tree, both qualitative and quantitative analyses of the tree were conducted. These evaluations revealed that reduced evacuation delays were most important in successfully evacuating from an underground mine fire. These analyses further showed that improved escapeway knowledge combined with improved self-rescuer training was also important. A brief evaluation was conducted to assess the importance of human versus engineered factors in the miner escape process. Several recommendations were given regarding human reliability under mine fire conditions.
