摘　　要：为了研究带有传送带的矩形巷道电磁波传播规律,提出一种基于电磁波传播理论和多波模理论的等效分析法,旨在降低研究电磁波传播计算的复杂性。利用计算机对有传送带的矩形巷道中电磁波传播规律进行仿真,将等效分析法方案计算出的仿真数据分别与矿井巷道中实际测量的3组数据进行对比分析。实验结果表明:等效分析法可以近似分析带有传送带的矩形巷道中的电磁波传播的情况,等高方案在30 m范围内的电磁波衰减规律更加符合实测数据。因此该方法可以应用在大型障碍物巷道中研究电磁波传播影响。In order to study the regulation of electromagnetic wave propagation in the rectangular tunnel with a conveyor belt,based on the electromagnetic wave propagation theory and multi-wave mode theory,an equivalent analysis method is proposed,which can reduce the computational complexity of the electromagnetic wave propagation regulations.The regulation of electromagnetic wave propagation in rectangular tunnel with conveyor belts is studied with computer simulation.The contrastive analysis between the simulation data calculated by the proposed method and the three sets of measurement data in the rectangular tunnel are carried out respectively.The experimental results show that the equivalent analysis method can approximately analyze the propagation of electromagnetic waves in the rectangular tunnel with conveyor belts,and the attenuation regulation of electromagnetic waves within the range of 30 m in contour plan is closer to the measured data.Therefore the proposed method can be applied to study of the influence factor of electromagnetic wave propagation in the tunnel with large obstacles.
