Due to the special security requirements and abominable environment, researching in the high reliability of the communication network and power in coal mine monitoring system is become special important. The reliability of the communication network and power in the coal mine monitoring system has been studied. To assess the reliability of the underground power and communication network, the constant stress accelerated life tests was presented based on the exponential distribution. The voltages and temperature were chosen as the constant accelerated stress parameters. Through the analysis of experimental data, the average life expectancy curves were obtained under different temperatures and voltage. With overall consideration of the communication network topology structure and network capacity the improved EED-SDP method was put forward in coal mine monitoring. It is concluded that reliability analysis of power and communication network in coal mine monitoring system is remarkably important to improve the reliability of coal mine monitoring system.
