Volume I of this report deals with theoretical, experimental, and practical implementation aspects of the federal Bureau of Mines programs related to present and planned, emergency and operational, mine communications and miner location systems for underground coal mines. Investigations, evaluations, experiments, and analyses for these programs were made; breadboard and prototype hardware was developed; and assistance was given in the formulation and presentation of technology transfer seminars on mine communications. Major subject areas treated in this volume are: electromagnetic noise and its measurement for mine environments, electromagnetic through-the-earth emergency and operational mine communications and miner location systems; signal propagation characteristics for wireless and guided-wireless radion waves in coal mine tunnels, and for mine hoist shaft and trolley wire communications; a mine pager phone-to-public telephone interconnect; paging and two-way communications with roving miners; technology transfer seminars and a through-the-earth state-of-the-art workshop on electromagnetic mine communications; and selected topics related to the above major areas.
