| 英文摘要 | During the data processing and interpretation of the mine transient electromagnetic method (MTEM), it is an important goal to improve the identification of the geo-electrical interface between low resistivity abnormal body and surrounding rock in advanced detection. To achieve this end, the transient electromagnetic field is transformed into the pseudo-seismic wave field based on the function relationship between spreading electromagnetic field and seismic wave field in whole-space. Meanwhile, the signal of pseudo-seismic after transform is processed with correlative stack to strengthen the amplitude and improve signal-noise-ratio (SNR) using the synthetic aperture imaging (SAI). The data of different detection directions on one surveying point in the MTEM are imaged as aperture data, which would highlight weak anomalies and improve SNR. In addition, the application effect of SAI was testified with the in-site-advanced detection in roadway using the MTEM. The results show that the SAI of the MTEM can improve SNR of the electrical interface information and highlight the geometrical resolution to increase exploration accuracy. The technique is significant theoretically and practically in accurate advanced detection of aquifer structure by the MTEM. |
