Abstract
Field research was directed toward evaluating the effectiveness of existing grounding systems used in U.S. coal mines, and a literature search was carried out to determine the effectiveness of various grounding systems employed in major coal producing countries of the world. Necessary instrumentation has been developed to analyze mine electrical power systems on a dynamic basis. Plans have already been made to develop a simulated mine electrical power system on which studies will be conducted to confirm and further analyze the findings from field research. Some protective devices have been acquired and more will be procured in the near future. Their performance characteristics and effectiveness will be determined in the laboratory with respect to the characteristics of existing mine power systems. The progress made in the various areas of research is presented in this report.
