    • Abstract
  • In view of complicated electromagnetic wave propagation environment in mine tunnel, a multipath channel model of electromagnetic wave propagation in mine tunnel was established by use of image method. In the paper, calculation methods of total propagation distance, incidence angle and reflecting angle of three-dimensional helix ray, and expressions of total receiving power and transmission loss were presented. The simulation results show that attenuation of electromagnetic wave field intensity is larger near transmitting antenna with fast fading phenomena, which verify the model can predict electromagnetic wave field intensity distribution in tunnel accurately.
