Propagation characteristics of radio waves in potash tunnels and its impact on radio systems / by S.M. Chow.: Co24-3/7-92-001E-PDF
"This report shows that radio waves at about 900 MHz can propagate in the tunnels of a potash mine with low loss and low multipath distortion. These results were first derived using a theoretical model and were later confirmed by measurements. The attenuation of radio waves per unit distance in a potash tunnel within this frequency band is less than the attenuation in a coaxial cable. This result is important because many commercial systems such as cellular radio, radio LANs and personal communication systems operate in this frequency band and can be adapted to work in a potash mine, replacing the more expensive leaky feeder systems used in other types of underground mines"--Abstract.
