The study presents the developed model of electromagnetic wave scattering occurring on the irregular surfaces. This model was implemented in the Ray launching (RL) method. Based on the modified RL, the analysis of electromagnetic wave propagation in an underground mine was performed. The results of theoretical analyses were compared with the results of measurements (from a copper mine) to determine the degree improvement in the electromagnetic field prediction accuracy after the developed model application.
