This report provides the results of an industrial engineering study that assessed the safety and efficiency of underground ore handling in U.S. metal mines. One of the primary findings of this study (Contract No. H0230004) was the improvement needed in controlling muck size in the ore handling stream. Oversize ore causes much additional labor, creates work stoppages, and is a principal cause of accidents in metal mines. The report includes data on block caving, back cut and fill, room and pillar, shrinkage stoping, and sublevel stoping methods.
