摘　　要：针对目前煤矿井下无线通信的状况,本文主要研究了矿井无线通信的频段以及电磁波在矿井矩形、拱形巷道内的传输衰减,分析了在矿井巷道内频率、截面、弯曲、分支、支护等多种因素对电磁波传输产生的影响,并通过仿真得出900～1000MHz为矿井无线通信的较佳工作频段。Basd on radio communication of the underground coal mine for the current situation,this paper mainly studies the band of the mine radio communication and propagation attenuation of electromagnetic waves in the rectangul、ararched tunnel,a various factors on the impact of electromagnetic waves propagation which frequency、bending、branch、supporting included is analyzed in the mine tunnel,and reached 900～1000MHz is better for the operating band of the mine radio communication through simulation.
