Modeling RF Propagation in Mines Using Wireless InSite

This paper presents results from modeling RF propagation in a mine using Wireless InSite. The Edgar Mine in Idaho Springs, CO provided the realistic scenario for the model. The path loss exponent was evaluated for a 5m section of the modeled mine by considering three different materials (concrete, dry earth, and dry granite) and three different standard deviation of surface roughness values for dry granite (0cm, 0.5cm, and 1cm). When comparing this simulated data with data retrieved from the Edgar Mine, it was determined that Wireless InSite's Uniform Theory of Diffraction (UTD) ray tracing code is capable of portraying a communications system within a mine environment.
