摘　　要：随着现代通信技术的快速发展,矿井中通信方式也由原来的有线通信向无线通信转变.随着近些年我国矿产资源的不断开发与利用,建设安全可靠的矿井通信系统成为了矿产高效生产和井下救援的必要措施.根据电磁波在矿井巷道中的传播特征,介绍了经典电磁波传播相关方程及多波模传输理论.为了简化巷道模型,重点分析了空矩形矿井巷道中的电磁波传播形式,并对巷道中存在的倾斜损耗、粗糙损耗等相关损耗进行了分析,最后通过MATLAB仿真分析,选择矿井巷道中适合电磁波传输的最佳频率段.With the rapid development of modern communication technology,the communication method in the mine has also changed from the original wired communication to wireless communication.With the continuous development and utilization of China’s mineral resources in recent years,the construction of safe and reliable mine communication systems has become a necessary measure for efficient mineral production and underground rescue.This paper focuses on studying the propagation characteristics of electromagnetic waves in mine tunnels,and introduces the classical electromagnetic wave propagation related equations and multi-wave mode transmission theory.In order to simplify the roadway model,the electromagnetic wave propagation form in the empty rectangular mine roadway is mainly analyzed,and the related losses such as the slope loss and rough loss in the roadway are analyzed.Finally,the matlab simulation analysis is performed to select the suitable electromagnetic wave transmission in the mine roadway optimal frequency band.
