Evaluation of the Black River Mine telecommunication system.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, Contract J0318074, 1983 Feb; :1-104
An evaluation was made of one of several improved underground communication systems sponsored by the U.S. Bureau of Mines. The system was installed in a typical metal-nonmetal, room-and-pillar mine and utilized ultrahigh frequency repeaters connected to a unique distributed antenna and passive reflector system that provided minewide communications. A microprocessor-controlled data collection system was assembled and installed for the evaluation. Data consisting principally of times and durations of messages and identities of the originating transceivers were collected over a 6-month period. Analyses of these data show that the principal benefits are reduction in time required for unscheduled maintenance and repair, enhancement of safety, and better coordination of production activities. A cost benefit analysis shows a net benefit over cost, although it is also concluded that the capacity of the system is greater than can be justified by current activity in the mine.
