通过测定不同地点的6种不同变质程度的构造煤在常温常压下的阻抗振幅，得到不同类型构造煤振幅谱各自不同的特点，在所测100 Hz~100 kHz 频率范围内，各类构造煤 Z–f(阻抗振幅–频率)呈一条单调递减曲线。在交变电场下烟煤的导电性较无烟煤及其他岩石差。在所测频段内，无烟煤 Z 值明显低于烟煤，且差值随着 f 增大逐渐减小。通过对构造煤 Z–M(阻抗振幅–水分)的拟合，得到相关公式；再利用所得构造煤阻抗振幅验证其公式可靠性，找出优势频段。初步分析了煤岩的幅频特性，为试图利用煤岩电性频率域响应特征差异来反映不同变质程度构造煤及与其他岩矿石的导电机理及结构模型，进而为用电法勘探物质组成与结构提供理论与实验基础。

Impedance amplitude measurement of six metamorphic kinds of tectonic coal was conducted under normal pressure and temperature. And then some phenomena were concluded as follows: amplitude spectrum of coal of different kinds respectively present different characteristics. In the test frequency range of 100 Hz~100 kHz, Z-f curves of coals all show monotone decrease. Through fitting of Z-M of tectonic coal, we can draw relevant formula, and use coal to validate, as the result, the edge band is obtained. In order to try to use coal and rock elec-trical response characteristic differences in frequency domain to reflect different conductive mechanisms and structure models of different coals and rocks, and then to use electricity exploration to prospect its compositions and structures, theoretical and experimental basis have been provided.
