由于传播环境的特殊性和复杂性,电磁波在煤矿井下存在着各种形式的衰耗。通过在某矿现场实验研究,并对采样数据进行分析,建立井下直线巷道无线电波传播衰耗预测模型。
Due to the particularity and complexity of the propagation environment, electromagnetic waves have various forms of attenuation in coal mines. Through the experimental research in a mine site and the analysis of the sampled data, a prediction model of radio propagation attenuation in straight-line roadway is established.
