Abstract
The unique problems associated with mine power system grounding are described, and the efforts that have gone on in this area over the years are traced. Special emphasis is given to efforts funded by the US Bureau of Mines. These include efforts aimed at improving ground-check monitor performance, designing and measuring the resistance of safety ground beds, analyzing ground-system safety and effectiveness, studying the effects of stray currents, identifying situations over which the effectiveness of standard designs may be lost, and communicating theoretical and field-verified findings to the mining industry. A well-referenced list of ground-system design considerations which should be familiar to those responsible for the design of mine power systems is included. An extensive annotated set of references which lists most of the grounding research published as the result of the Bureau of Mines research efforts is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
