This report covers a technical and economic investigation of old electrical power systems, equipment, and practices being used in the metal-nonmetal mining industry. The principal sources of information were the MSHA district offices, visits to representative mines and mills, equipment manufacturers, and the literature. A list of 85 mines and mills, submitted by the MSHA districts as candidates for this study, is given and their characteristics are analyzed. The electrical power systems and practices at the 10 mines and 9 mills that were visited are described. The principal areas that do not conform to standard electrical practices are discussed with emphasis on the safety aspects of these practices. The costs to update electrical power systems and practices in metal- nonmetal mines and mills are given. The principal findings of the study are summarized and recommendations are submitted.
