| 英文摘要 | The rapid development of Chinese economy has led to increase in the demand for mineral resources, while surface and shallow minerals are currently decreasing. Therefore, it is important to explore for new blind ore bodies at depth. The Controlled Source Audio-frequency Magnetotelluric Method (CSAMT) has been highly effective in geophysical prospecting with wide detection range and high resolution. However, CSAMT prospecting for deep subsurface mineral resources in mining areas is subjected to different types of strong electromagnetic interference. Due to the limitation in data resolution at depth, the effective application of CSAMT in mining areas is greatly affected. To solve this problem, this work attempts to place the CSAMT acquisition array system in the roadway, making the receiver system closer to the underground target or passing through different geological boundaries. The proposed array is expected to improve the accuracy of target identification and increase the efficiency and success rate of deep resources exploration. The forward modeling of different types of geological bodies based on the integral equations, and analysis of the CSAMT response characteristics for the different models at different depths are performed. The results obtained from the integral equations are validated by two-dimensional modeling results from MARE2DEM. The results show that in anoise-free environment, although the electromagnetic field signal received in the roadway is weaker than that recorded on the surface, its resolution to the deep blinded ore body or target is better. |
