Utilization Of A Mine-Wide Data/Communications System At Kitt #1 And Amonate Mines

A fully field tested mine-wide data/communications system is presented which integrates total data acquisition, control, and instrumentation into a single system. Installations at Kitt #1 and Amonate Mines (W.Va.1 use an LSI-11 series computer which communicates with easily installed field data stations over a single twisted wire pair. Complete field test data are presented, identifying the problems and successes experienced in the development, installation, operation and maintenance of the system, and the training of mine personnel. Of particular interest is the system installed at Kitt #1 which has been in continuous use since February 1982. The paper will also deal with the application of a computer-based carbon monoxide monitoring system installed at the Amanate mine in September 1982. The purpose of that system is to monitor air quality and to provide early fire detection in the belt entry to permit the use of belt air for face ventilation.
