根据矿井瞬变电磁理论和电磁感应原理,遵循物理模拟相似性准则对井下分布在瞬变电磁探测天线同侧和异侧的典型柱状低阻异常体的响应特征进行模拟实验研究。通过对实验结果的处理和分析得出结论:同侧和异侧典型柱状低阻异常响应特征在多测道剖面图上均表现为“拱形”形态,但异侧的响应特征与异侧又有所区别,异侧相邻异常产生相反方向的感应电位的抵消作用会使得“拱形”顶部出现一极小值点的现象。 According to the mine transient electromagnetic theory and the electromagnetic induction principle, the response characteristics of the typical cylindrical low-resistivity anomaly distributed in the same side and the opposite side of the transient electromagnetic detecting antenna are simulated and simulated according to the physical analog similarity criterion. Through the treatment and analysis of the experimental results, it is concluded that the typical low-anomalous columnar responses of the ipsilateral and the lateral heterosis show the “arch” shape on the multi-track sections, but the response characteristics of the opposite side are different On the other hand, there is a difference between the two sides. The counteraction of the induced potential in the opposite direction of the opposite anomaly will make the phenomenon of a minimum point appear at the top of the “arch”.
