摘要: 针对矿井隧道复杂的电磁波传播环境，利用镜像法建立了矿井隧道电磁波多径信道模型，给出了三维空间的锯齿螺旋射线总传播路径长度和入射角、反射角的计算方法，以及总的接收功率和传输损耗的表达式。仿真结果表明，靠近发射天线的电磁波场强衰减较大，呈现快衰落现象，所建模型能准确预测隧道中电磁波场强分布。

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.
