| 摘 要： | 南水北调中线工程，是采用明渠开挖自流引水方式，其沿线经过多个煤田地区，探明线路上的采空区尤为重要，本文以南水北调中线禹州采空区为例，阐述了可控源音频大地电磁法（CSAMT）的基本理论、野外工作措施，并结合该区地质概况，准确探明采空区的位置、深度。探测结果与煤田钻孔地质剖面图、采空区钻孔验证基本吻合。说明CSAMT法在复杂多个煤系地层探测采空区的有效性。

| Abstract: | Because the open channel excavation and water extraction methods are used in the middle route of South-to-North Water Transfer Project,and this route goes through many coal fields,it is very important to prove up the route of the goaf.In this paper,the author takes the Yuzhou goaf as an example to elaborate the basic theory of CSAMT method and the measures of field work,and based on the geology to prove up the location and depth of goaf accurately.The exploration result basically accords with the geologic profile of coal field bores and bore validating of goaf.This work shows the validity of CSAMT Method being applied to the goaf exploration in complex multi-coal-stratum. |
