摘要:
提要:为评价国产本安型矿井瞬变电磁仪YCS40(A)的稳定性及对异常体的分辨能力,特将其同井下使用较频繁的进口仪器TERRATEM做了试验对比。试验中,进行了二款仪器使用各自的常规装置展开单点背景值实验对比、对异常体的分辨能力实验对比和抗干扰能力等模拟实验对比。并在同一感应电动势-衰减时间(V-T)的坐标下考察二者的关断时间、感应电动势的幅值、光滑程度及衰减速率和尾期信号的抗干扰度等衡量仪器性能的硬性指标。最后通过井下实际工程实例剖面测量对比,表明国产YCS40(A) 矿井瞬变电磁仪具有稳定性较好、抗干扰能力强、对异常体具有较强的分辨能力等优点,同时也感到该仪器探测窗口较少、感应时间短,当井下异常体埋深超过120 m时其分辨力的不足。

Abstract:
Abstract:In order to evaluate the home-made intrinsic safety type mine transient electromagnetic instrument YCS40 ( A ) and its stability of the anomalous body resolution, the authors made a comparative study of the performance between this instrument and the frequently-used imported instrument of TERRATEM. In the experiment, the two instruments used their respective conventional device to conduct experimental contrast of single background values, the anomalous body resolution experiment contrast and the anti-jamming simulation experiment. And under the condition of the same EMF - decay time (V-T ) coordinates, the authors investigated their performance indices such as off time, induction electromotive force amplitude, and attenuation rate of smooth degree and period signal anti-interference degree. The downhole practical engineering measured profile survey contrast shows the home-made YCS40 ( A ) mine transient electromagnetic instrument has the advantages of good stability, strong anti-interference capability, fairly high resolution capability for anomaly body, but has the shortcomings of insufficient detection window, short induction time and insufficient resolution when the depth of the underground anomaly exceeds 120 m.
