NTIS: PB/81-130726 :308 pages
The objectives of this study are to (1) survey electrical practices in metal and non-metal mines and mills, (2) clarify the federal regulations governing electrical practices, (3) analyze electrical accidents, and (4) make recommendations aimed at improving the safety of electrical practices. Information was obtained from literature searches, accident reports, visits to 27 mines and 12 mills, and discussions with knowledgeable industry and government people. The various electrical power systems and practices at the mines and mills visited are described. Similarities and differences based on the type of mining and the minerals being mined or milled are presented. The federal regulations governing metal-nonmetal mine and mill electrical practices (code of federal regulations, title 30, sections 55.12, 56.12, and 57.12) Are presented and discussed. An analysis of the electrical accidents in metal- nonmetal mines and mills during the period 1972-78 is presented.
