Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, Contract J0395072, Contract H0377013, 1979 Jul; :1-163
This report describes a complete system design methodology for medium frequency (MF) wireless radio systems for use in coal mines. The emphasis is on AC mines where no trolley wire exists and, for which, conventional trolley phone communications can not be used. The report constitutes an MF system design handbook and includes a compendium of all previous MF technology elements as well as a reference index with abstracts of all pertinent literature. A particular strawman system design analysis is included for the Helvetia Coal Co. Lucerne #8 mine in the Upper Freeport Seam.
