摘　　要：针对煤矿井下这种受限非自由空间的特殊通信环境中多输入输出(MIMO)技术的应用问题,研究了影响煤矿巷道MIMO信道容量的多种因素,并进行仿真分析,结果显示MIMO在煤矿巷道中的应用有一定的可行性和实用性。同时,为了得到在井下复杂环境下MIMO的最大信道容量,利用粒子群算法给出了用于煤矿巷道中MIMO天线布置的理论公式。According to the application problems of MIMO（Multiple Input Multiple Output） in the special communication environment of the restricted non-free space in the underground mine,the multi factors affected to the MIMO information channel volume in the underground mine were studied and the simulation analysis was conducted.The results showed that the MIMO applied to the mine roadway could have certain feasibility and practices.In order to have the max information channel volume of the MIMO in the complicated environment of the underground mine,the particle swarm algorithm was applied to the theoretical formula of the MIMO antenna layout in the mine roadway.
