Design Criteria for Panic Bars and Auger Miner Safety. Auger Miner Safety Study. Volume 7. Final Report.

摘要

The study developed designs to facilitate and accelerate auger rotation stoppage (and auger rotation start up so as to promote auger disengagement during miner responsibility) and to provide a time delay and warning signal prior to auger start up to permit any miners near the augers to get away from the augers before they start rotating. In the underground coal mines in the United States,there are four auger miners that are currently in use. They are the Jeffrey 100L and 100M,and the Wilcox WCM and the MK20A.
