摘　　要：为了探究UWB无线信号在煤矿巷道内的传输特性,结合电磁波信号的传输以及反射定律原理,分析了矩形矿井巷道中可能出现的不规则传输路径其过程中存在的粉尘浓度、空气湿度、四壁不同程度的粗糙面以及煤壁倾斜程度等因素引起的信号损耗。构建了不同条件下的损耗模型,并运用MATLAB软件对巷道内信号的损耗进行了仿真分析。仿真结果表明:粉尘浓度和空气湿度都会对电磁波造成衰减,增加粉尘浓度加速信号的损耗,其信号的衰减要远大于空气湿度引起的损耗;粗糙和倾斜加速了信号的衰减,但是粗糙和反射引起的损耗远远低于倾斜引起的损耗,倾斜损耗起主导作用。In order to explore the transmission characteristics of UWB wireless signal in coal mine roadway.By integrating the principles of electromagnetic wave transmission and the laws of reflection,it analyzes signal losses attributed to various factors:dust concentration,air humidity,surface roughness of walls,and the inclination degree of coal wallswithin irregular transmission paths found in rectangular mine roadways.Distinct loss models are formulated under diverse conditions,and MATLAB software is utilized to simulate and analyze signal loss within the roadway.The simulation results reveal that both dust concentration and air humidity contribute to electromagnetic wave attenuation.Notably,an escalation in dust concentration significantly amplifies signal loss,surpassing the impact of air humidity.Furthermore,the study highlights that while surface roughness and wall reflection contribute to signal attenuation,their impact remains notably lower compared to the loss incurred due to wall inclination.Wall inclination emerges as the predominant factor driving signal loss.
