摘要:

基于聚焦双频激电法原理设计并制作了聚焦双频激电仪,模拟井下环境建立了土槽实验台并构造了含水异常体,给出了实验台的详细设计过程。基于垂直于煤巷断面的特殊布极方法,在无偏转条件下,通过变换屏流比和两测量电极的相对位置关系,测得在有无含水异常体下的视幅频率数据。根据数据分析得到了此条件下的最佳屏流比及最佳测量电极位置。

Focused dual frequency IP instrument has been designed and fabricated based on the principle of focused dual frequency induced polarization method. Then we established soil trough experiment platform and structured the abnormal water bearing body by simulating conditions of the coal mine, the detailed design process of experiment platform is given. Based on special electrode layout mode that the electrode is perpendicular to the roadway section, on the condition of no deflection, we got the apparent amplitude frequency data with and without abnormal water bearing body by changing the bucking current ratio and the relative position between the two measuring electrodes. And we obtained the best bucking current ratio and measurement electrode position under these conditions according to data analysis.
