Abstract
This report describes the results of investigations into four specific areas related to trolley wire power distribution in coal mines. Prototype devices or designs were developed in each area. In addition, a brief survey was made in an attempt to assess the future of mine trolley systems, and data were collected and reviewed in an attempt to analyze the nature of trolley wire related accidents. Other options for decreasing the risks associated with trolley systems that arose during the study are briefly discussed in the appendices. These include insulating equipment and miners from return and/or energized conductors and use of a segmented trolley wire with local control of current-delivering capability.
