| 英文摘要 | The Multi-Channel Transient Electromagnetic Method(MTEM)adopts pseudo-random code transmission and best matching coherent decoding technology, thus its exploration depth is larger and the anti-interference ability is stronger than the traditional time domain electromagnetic method, and it becomes a research focus in ground resource exploration. This paper presents the application of the method to a lead-zinc-silver mine in Xingan League of Inner Mongolia. In view of its large burial depth, firstly, we establish a one-dimensional and a two-dimensional model based on the data of the mining area. Then we calculate the impulse response and analyze its characteristics. Results show that the MTEM can reflect well the resistance anomalies at large depths. This technology is used to carry out an example survey in the mining area. In the data processing process, the deconvolution method is used to extract the earth impulse response, and the apparent resistivity is calculated according to the peak moment of the axial ground impulse response. The full-waveform inversion of the apparent resistivity yields an explanatory profile. The comparison with the borehole data of the survey area proves that the MTEM is an effective method to reveal bodies with low-resistance anomalies in the deep subsurface. |
