摘　　要：煤矿安全生产监控系统的通信网络可归纳为单分站单设备、单分站双设备、双分站单设备和双分站双设备几种组网模式,通过对其任务可靠性和基本可靠性进行比较分析,综合考虑任务完成概率和维护成本两方面的要求,提出了双分站,局部(高故障点处)双设备的组网模式,以期有效提高通信网络的系统可靠性。The communication network of coal-mine monitoring system for work safety can be divided into 4 categories： single monitoring station-single equipment, single monitoring station-double equipment, double monitoring station-single equipment and double monitoring station-double equipment. By comparison and analysis on the mission reliability and basic reliability of these network, and comprehensive consideration of their task-fulfilling probability and maintenance cost, the paper selects double station-single equipment with double equipment fixed in high fault point as the mode of communication network so as to enhance the communication reliability of coalmine monitoring system.
