摘　　要：通过分析电磁波在煤矿井下巷道的传播特性,对电磁波定位的3种基本方法在井下的适用性进行了分析,初步得到了TOA方法实现定位是可行的结论,并且通过在空直巷道以及有障碍巷道中分别进行测试,测试结果进一步表明,用TOA方法实现井下的定位是可行性的。This paper has analyzed the characteristics of radio propagation in mine tunnels and researched the feasibility and efficiency of the three precise location methods RSS,TOA,AOA. On the base of the analysis, it is concluded preliminarily that the TOA is more feasibility. The experiments in clear tunnels and obstacle tunnels have carried out and the results show that TOA is efficiency in position location in mine tunnels.
