瞬变电磁法在某煤矿采空区勘探中的应用

Application of TEM in a Coal Mine Goaf Investigation

该文结合工程实例,介绍了瞬变电磁法在某煤矿采空区勘探中的应用。根据场地地质条件及施工条件,合理布置物探测试工作,将所测数据按解译程序解译后与场地地质条件相结合,分析得出煤矿采空区的分布深度与范围,并将勘探成果与钻孔资料进行了对比分析,查明了采空区的发育特征。通过该工程,验证了瞬变电磁法在煤矿采空区勘探中的有效性与准确度,并为其它煤矿采空区勘探工作提供了有益的参考。

Combined with an engineering example, this paper introduces the application of transient electromagnetic method in a coal mine goaf investigation. Based on the working site geological conditions and construction conditions, the test working of geophysical prospecting is arranged reasonably. The measured data is interpreted according to the interpretive program, and then combined with the site geological conditions, the depth and scope of the coal mine goaf are analysed and obtained. The exploration results and borehole data are compared and analyzed, and the development characteristics of mined out area are identified. Through the project, the validity and accuracy of transient electromagnetic method in the exploration of coal mine goal are verified, and it provides a useful reference for the exploration of other coal mine goafs.
