Abstract
Mine electrical system parameters were determined using the data contained in survey reports of five different coal mines. The typical electrical characteristics of the trolley-rail distribution system were calculated, and worst case conditions for fault protection were defined. Calculated system parameters were corroborated by underground measurements in a working coal mine. Concepts for providing a fault discriminating circuit breaker were investigated, and one scheme was selected for development. A laboratory prototype of the discriminating breaker suitable for evaluation in a mine was built and tested.
