To optimize the antenna layout for mine wireless communication systems, a 3D model of a rectangular roadway measuring 5 m in width and 3.4 m in height was constructed using the Shooting and Bouncing Ray tracing (SBR) method. A multi-scale analysis of power attenuation characteristics in the 0.9 GHz, 2.4 GHz, and 3.5 GHz frequency bands within roadways was conducted across transmission distance, longitudinal cross-section, and spatial distribution. The impact of antenna positioning on wireless transmission was also investigated. The results show that the 0.9 GHz frequency band exhibits superior transmission characteristics compared to the other two bands. The mean longitudinal cross-sectional power at different transmission distances is 6.60-9.17 dBm and 10.49-12.63 dBm higher than that for 2.4 GHz and 3.5 GHz, respectively. The optimum horizontal position for the antenna is within 0.01 to 0.1 m from the roadway wall. When the antenna was deployed flush against the wall (within 0.01 m of the wall), the spatial power distribution exhibites an asymmetric characteristic. The received power in the adjacent wall area on the same side as the transmitting antenna is 1 to 4 dBm higher than on the opposite side. A stable and strong reception signal can be obtained when the height difference between the transmitting and receiving antennas is less than 0.5 m. The research findings may serve as a reference for optimizing base station placement and antenna layout within roadways, thereby facilitating the development and construction of intelligent communication systems for mining operations.

为优化矿井无线通信系统天线布局,采用入射及反弹射线法(Shooting and Bouncing Ray tracing, SBR)构建宽5 m、高3.4 m的矩形巷道三维模型,从传输距离、纵向切面和空间分布多尺度系统分析0.9 GHz、2.4 GHz和3.5 GHz频段在巷道内的功率衰减特性,并研究天线位置对无线传输的影响。结果显示:0.9 GHz频段传输特性优于其他两个频段,不同传输距离的纵向切面功率均值较2.4 GHz和3.5 GHz分别高出6.60~9.17 dBm和10.49~12.63 dBm;天线最佳水平位置为距巷壁0.01~0.1 m,当天线紧贴巷壁(距巷壁小于0.01 m)部署时,功率空间分布呈非对称特性,发射天线同侧邻壁区的接收功率比对侧高1~4 dBm;收发天线高度差小于0.5 m时可获得稳定且较强的接收信号。研究结果可为优化巷道中基站设置和天线布局提供参考,有助于推动矿山智能化通信系统的开发和建设。
