摘要
本文以金乡－单县隐伏型石炭、二叠系煤田为例，论述和分析利用曲线类型来划分煤层的分布范围，利用电场特征来划分断裂构造，推断构造轮廓，在不易掌握各电性层电性参数的情况下，准确求出煤系底板的埋深，并通过与部分钻孔对比，分析电测深资料的有效性。
Electrical prospecting is an economical and highly efficient way to pr ospect coal fields.It cantell the exact structural forms of a coal basin. We may Know the distribution and range of coalmeasures by analyzing the types of electrical sounding curves resulted from the coal measures anddetermine the depth of the coal measures by guantitative interpretation of the curves. Taking the Concealed coal fields occurred in the Carboniferous and Permian systems in theJin-xiang and Shanxian areas as an example,the authar explains how to use the types ofelectrical curves to determine the range(boundaries)of the coal fields and how to use thecharacteristics of the electrical fields to know fault structures and to infer the structural contours.In this way the footwall depth of the coal measures can be precisely derived even if the electricalparameters of different electrical horizons are difficuIt to know. Finally,a comparison of electricalsounding data to some drilling data has been made to show the effectiveness of the method
