| Abstract: | The uniformly spaced of delay tap line model was used to researcher the propagation of the radio waves in coal mine tunnels at 2.0GHz in this paper.The researcher result shows that: the RMS delay expansion of the wide band radio waves propagation is in the coal mine tunnel,which is consistent with the actual measurements. |
