摘　　要：为了实现矿业的本质安全、高产高效、绿色环保的目标,顺应“智慧矿山”时代的发展,提出了基于双向传输的矿下通信网络。通过解码转发协议进行用户间的信息交互,从而扩大中继网络的作用区域,提高通信的可靠性以及频谱效率。然后通过推导中断概率、覆盖范围、信噪比增益概率和时延中断率的解析表达式,更全面地对所提出网络的性能进行分析。仿真结果表明,平均发射信噪比、信道衰落参数、相对链路增益和时间持续阈值等系统相关参数均对系统的性能有着重要影响。In order to meet the essence of the mine safety,high efficiency and green environmental protection demand,and conform to the development of“intelligent mine”era,this paper discusses the underground mine communication network based on two-way relay transmission,which takes the decode-and-forward protocol to realize the information interaction among users and thus to enlarge the coverage area of the considered relay network,improve the reliability of communication and spectrum efficiency.Then,the analytical expressions of outage probability,coverage distance,probability of signal-to-noise ratio gain and delay outage rate are derived to comprehensively analyze the performance of the considered network.The simulation results indicate that the system parameters such as average transmission signal-to-noise ratio,channel fading parameters,relative link gain and time duration threshold have important effects on the system performance.
