Abstract EN
This study investigates the mechanism of channel wave multipath propagation to determine features of a channel wave in a coal seam.
For this purpose, deduction formulas were used for different time delays and propagation paths and, subsequently, a multipath fading channel wave pattern was built.
MATLAB software was used to simulate the model.
To this end, the characteristics of the coal seam and the surrounding rock were considered.
The simulation results were compared with results obtained from the model contained in COMSOL software to verify the accuracy of the model.
According to the results obtained from the simulation, the proposed model shows a good match with the COMSOL model, which is a common simulation comparison standard.
In addition, the channel wave energy approximates to exponential decay at a constant distance from the source, and the multipath propagation considerably affects its energy attenuation.
Furthermore, the multipath reflections’ travel time derivation is accomplished properly in the coal seam.
