Abstract Based on the study of the electrical properties of the disturbed and gas logged coal mass and the oppsite kind of coal mass, the authors probed into the radio wave responed characteristics of the disturbed and gas logged coal seams, thus providing theoretical basis for the application of radio wave perspective technique to the detection of disturbed and gas logged coal mass and the noncontact prediction of disturbed and gas logged zones.
