| 摘 要： | 采用自主研发的多通道大功率电法勘探仪进行了深部矿勘探测试.首先在河北省张家口市张北县进行了仪器整体的调试和波形测试等试验,试验结果表明,在大偏移距情况下,尽管存在50 Hz电磁干扰,也能获得与发射波形相关的波形曲线,验证了仪器系统的正确性和稳定性.然后在内蒙古曹四夭钼矿区采集了4.8km的剖面数据,并进行了相应的数据处理工作.对所采集的数据进行了大地脉冲响应计算、峰值时刻提取和视电阻率计算,以及电阻率二维反演工作,反演的的电阻率断面结构与已知地质资料相吻合,验证了数据流程和处理方法的正确性.此次多通道大功率电法勘探仪的成功集成,为进一步大规模比对试验和装备整装勘探打下了基础.

| Abstract: | Independent development of a multi-channel transient electromagnetic (M-TEM) system has entered the instrument integration stage. Firstly, the debugging and the waveform measurement of the instrument have been successfully conducted in Zhangbei county, Hebei Province. In the case of large offset, at the presence of the 50Hz electromagnetic interference, it can get a good correlation with emission waveform for received curves, which shows that the overall performance of the instrument is stable. Afterwrads, the experimental test was carried out at a Mo mine of Caosiyao, Inner Mongolia. The 4.8 km profile data were acquired and processed, followed by picking peak times and calculating apparent resistivity from recorded data, and 2D inversion conducted. The shape of 2D inversion section is in agreement with the known geological data. These have laid the foundation for the large-scale comparive test and equipment exploration in the subsequent work. |
