| 摘 要： | 用频率、瞬变电磁测深和人工地震方法在淮北西寺坡区推覆体下找煤,定性分析出推覆构造的存在、推覆范围和盖层厚度。在简述了3种方法进行此项勘探的原理和优缺点后,认为电磁测深在穿透高阻盖层方面效果比较显著,并用野外实测曲线、理论正演模型和钻探结果对比加以证实。

| Abstract: | The coal under the overthrust in Xisipo,Huaibei district was looked for with seismic,frequencial and transient domain electromagnetic soundings.The thickness of the overlay and the range of theoverthrust have been qualitatively analysed.The theories and advantages and weakness of above threemethods on the survey were simply recounted.It is thought that electromagnetic soundings has moreefficiency on penetrating high resistive overlay and this has been proved by the raw curve,theoretic modelsand drilling. |
