综合物探方法在矿山覆盖区地质调查中的应用

Application of Comprehensive Geophysical Prospecting Method in Geological Survey of Mine Covered Areas

由于矿山覆盖区第四系覆盖严重,地质工作程度整体较低,地表露头少,地层、构造以及岩体等无法通过地表露头直接观察,多以中小比例尺综合性调查工作为主。本次山东省1:50000区域地质调查项目,利用可控源音频大地电磁测深(CSAMT)和浅层二维地震测量方法在覆盖区的较强的分辨能力,查明矿山覆盖层下断裂构造的发育特征和第四系厚度分布特征,进一步提高地质研究水平,对本次工作具有重要的参考利用价值。本研究成果可为今后在山东省第四系覆盖区,开展矿山区域地质调查工作提供技术参考,具有一定的借鉴意义。

Due to the serious coverage of the Quaternary system in the mine coverage area,the overall degree of geological work is low,and there are few surface outcrops.The stratum,structure and rock mass cannot be directly observed through the surface outcrops,and most of them are based on small and medium-sized comprehensive surveys.This 1:50000 regional geological survey project in Shandong Province uses the strong resolution of controllable source audio frequency magnetotelluric sounding(CSAMT)and shallow two-dimensional seismic survey methods in the coverage area to find out the development characteristics of fault structures under the mine overburden and the distribution characteristics of Quaternary thickness,further improve the level of geological research,which has important reference value for this work.The results of this study can provide a technical reference for carrying out regional geological survey of mines in the Quaternary coverage area of Shandong Province in the future,and have a certain reference significance.
