Don't let unsupported roof go unnoticed: what you don't.
Holmes Saf Assn Bull 1993 Apr; 20-23
Coal miners do not like the idea of being under unsupported roof. Most of them know that roof falls are the leading cause of fatal accidents among underground coal miners. About half of the victims of these accidents are under unsupported roof at the time they are killed. It is disturbing to suddenly realize that you are standing in an area where the roof has not yet been supported - nothing is preventing you from being crushed by thousands of tons of rock at any moment. Yet, many coal miners unintentionally find themselves in this situation on a rather frequent basis. To discover more about this problem, Bureau of Mines researchers recently interviewed 268 miners from 6 different mines. They wanted to find out (1) how often miners unintentionally find themselves under unsupported roof (2) why it happens, and (3) how it can be prevented.
