作者根据过去的研究,预计利用800兆赫频带井下无线电通讯技术可以达到实用目的。以开发新型井下超高频无线电通讯系统为目标,为获得巷道内电波传播特性的详细基础资料和利用可靠性高、基本实用的漏泄同轴电缆通讯系统的资料,在各煤矿巷道中进行了电波传播试验和在巷道内设置漏泄同 Based on past research, the author expects to achieve practical purposes using down-hole radios in the 800 MHz band. In order to develop a new type of underground UHF radio communication system as the goal, in order to obtain the detailed basic information of the propagation characteristics of radio waves in the roadway and the use of reliable, basic and practical information of the leakage coaxial cable communication system, Propagate the test and set the same leakage in the tunnel
