By combining free space and modified waveguide propagation models, we propose a new hybrid propagation model based on ray tracing. Simulation results have shown the effectiveness of establishing a wireless Local Area Network (LAN) in this coal-mine environment. The results of this research will be very useful as a guide in the design and development of tunnel wireless LAN systems. 关键词：无线局域网系统隧道环境煤矿环境 WLAN 性能分析无线通信系统传播模型矿井巷道
