Abstract
A medium-frequency (MF) wireless communication system for underground mines, a new telecommunication system, works on low loss electromagnetic wave propagation modes that allow it to provide quality radio communications almost anywhere in a mine. Tests show the mf system can provide improved safety and managerial control, increased productivity, better organizational teamwork, and reduced maintenance costs; furthermore, the mf system's unique design allows for easy installation at a minimum cost. This report covers (1) the mf design plan, (2) an overview of mine radio communications systems, (3) preparations needed for designing an mf system, (4) MF equipment, (5) MF installation, (6) MF design considerations, (7) MF design specifications, and (8) recommendations dealing with the system. Experiments in four mines are illustrated to demonstrate the success and viability of the mf system. The mines range from small (500 tons/day) to large (67,000 tons/day) capacity and represent several different mining methods. The MF wireless communication system represents an advancement in mining communication and the groundwork for other advanced mine systems.
