随着通信技术的发展，地面移动通信技术在不断提高，但是煤矿井下移动通信技术进展缓慢，主要是由于矿井下恶劣的通信环境以及对通信的特殊要求。为了使复杂的问题简单化，文章将矿井巷道理想化，根据理想波导理论，研究了直巷道内电磁波的传输特性和损耗特性，并且估算了TE10波在一定的巷道壁电导率情况下的损耗和传输距离，本文对巷道内无线电通信的发展有着重要的理论指导意义。

With the development of communication technology, mobile communication technology are enhanc-ing continually, but the development of mine mobile communication technology is very slow, mainly due to poor communication environment and the special requirements on communication under the mine. In order to make the complex problem simplified, this paper assumes the mine tunnel ideal. According to the ideal waveguide theory, the article studies the transmission characteristic and loss characteristic of electromagnetic wave in the straight tunnel, and estimates the loss and transmission distance of the TE10 wave, in the case of certain tunnel wall conductivity. There are important theoretical guiding significance to the development of the tunnel radio communication.
