Description:"Eight coal mines were visited to determine their communications usage and requirements. Presently available equipment was surveyed and evaluated to determine its applicability to the needs of the mines. The requirements, as determined from the surveys, and the capabilities, as determined from analysis and experiments, were summarized. Volume 1 summarizes the entire report and includes both a dissertation on the strengths and weaknesses of various available communication techniques and a set of requirements for several grades of comprehensive mine communication systems." - NIOSHTIC-2
