Abstract :
This paper analyzes the special environment of underground coal mine, and points out that the existing underground communication is poor. It is very necessary to use suitable means to communicate under coal mine. Because of the special environment, there are no reports about the using of PLC underground. In this paper, the main underground PLC channel characteristics are analyzed by measuring and simulating, such as noise characteristics, input impedance characteristics, channel attenuation characteristics, and multipath characteristics. Based on the analysis of these characteristics, the work will come to an conclusion that the application of PLC underground is suitable and feasible.
