Abstract
Roof warning signals were studied in 18 mines covering 5 coal seams. The results of this study (Contract No. G0133026) confirmed that roof talk must be interpreted for each individual mine after all other conditions are present that indicate danger of roof fall. Roof talk and machinery noise records obtained during this study were used for subjective tests of ear protectors in a simulated coal mine noise environment. Results of these tests showed that the use of personal ear protectors in high noise levels does not degrade a miner's ability to discriminate speech and roof talk. A training course was developed to encourage coal miners to protect their hearing by proper use of personal hearing protectors.
