| Abstract: | The article has analyzed the main performance which affected the transmission of signal of the underground leakage communications system in coal mine, proposed the basis of the leakage coaxial cable selected , established the mathematical model of leakage coaxial cable in coal mine . It is concluded that the different coupling loss of the leakage coaxial cable has been selected to lengthen the transmitting range, and the coupling loss has been gradually reduced to obtain stable received signal. |
