摘要:Abstract: 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.
