Mining Publication: Research and Development Contract for Coal Mine Communication System: Volume 4 - Environmental Measurements
ShareCompartir
Original creation date: November 1974
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 4 describes the propagation measurements made in selected mines during the project, along with findings resulting from these measurements.
