一、无线电波透视法的原理和工作方法1.基本原理电磁波在煤层和其它不同介质中的传播,引用的是在空气中的传播理论。无线电波透视法的实质是研究无线电波在不同介质中的不同传播现象,是基于煤、岩层的电性差异来确定地质异常.无线电波能穿透相当距离的煤、岩层,但因其电性不同,所以,对无线电波具有不同的衰减作 First, the principles and working methods of radio wave perspective 1. The basic principle of electromagnetic waves in the coal seam and other media in the spread, the reference is in the air propagation theory. The essence of the radio wave perspective is to study the different propagation phenomena of radio waves in different media and to determine the geological anomalies based on the electrical differences between coal and rock strata. Radio waves can penetrate coal and rock formations at considerable distances. However, Different, therefore, have different attenuation of radio waves
