Abstract

The research done over the last decade or so toward the application of the principles of reliability theory to mine electrical power systems is summarized. The work can be divided into two major portions. The first portion describes the multifaceted effort to estimate the failure rates of equipment applicable to the mine environment. The second part deals with the use of fault tree analysis to predict the probability of hazardous voltages on the frames of various pieces of mining equipment. The primary emphasis is on underground coal mines, but some results have also been developed for other types of mining operations. For the underground coal mine case the analysis has been developed to the point where an estimate of fatalities and lost time injuries is available to compare to historical records. This comparison is reasonably close and instills a great deal of credibility in the modeling effort. © 1988 IEEE
