摘要
为研究煤层顶板砂岩的裂隙富水区分布情况,采用瞬变电磁勘探方法,在资料处理时利用三维地震提供的砂岩埋深及厚度对瞬变电磁资料进行约束反演,得到目的砂岩层电阻率分布情况。利用岩层电阻率与富水性的关系,计算出目的砂岩层的含水情况,为指导煤矿安全开采提供了直接的资料。
The transient electromagnetic exploration （TEE） is applied to study the distribution of the fissure waterbearing zone in the roof sandstone of coal seam. In the processing of TEE data, the depths and thicknesses of strata achieved from 3-D seismic exploration are adopted for the restricted inversion and the resistivity distribution of the aimed sandstone is obtained. The water-bearing state of the aimed sandstone is calculated by means of the relation between the resistivity and water-bearing capability of rocks, providing the directive information for the safe production in the coalmines.
