矿井巷道中水分较多,巷道围岩因吸收水分而变得潮湿,进而引起围岩电导率发生改变.通过分析湿度对围岩电导率的影响,研究了湿度对圆形巷道和矩形巷道中电磁波传播的影响.结果表明,在矿井移动通信频率范围内,当矿井水电导率较低时,湿度对电磁波传播的影响很小（可忽略）;当矿井水电导率较高时,随着湿度的增加,其对电磁波衰减的影响随之增加.

There are more water in a mine tunnel.Due to absorbing moisture,tunnel walls will be wet to change the conductivity.This paper analyzes the mechanism of humidity influencing on the conductivity of tunnel walls,and attenuation of electromagnetic waves propagation in a circular tunnel and a rectangular tunnel.The study result shows that in the mine mobile communication frequency range,when the mine water conductivity is low,the humidity has little effect on the propagation of electromagnetic waves,and it can be neglected;when the mine water conductivity is high,the propagation attenuation increases with the humidity.
