Abstract
This paper reports the results of a 2-year research effort aimed at improving communication systems used in coal mines. This work was conducted under a program, the original goal of which, not only involved the development of practical and effective electronic systems for operational communications, but also for monitoring, at a central location, remote instruments at key positions in a mine. About half way through the originally proposed 3-year effort, the program was redirected to phase out the communication effort at the end of 2 years and to concentrate the program's resources on the investigation of new monitoring system concepts developed by this research. The latter was carried to the point of providing sufficient evidence to aid in the comparison of certain new communication concepts. For the concepts chosen for this study, the work was stopped short of hardware development and field testing.
