摘要
摘要:最新的成矿理论研究和深部定位预测结果均表明我国大陆2000 m深部蕴藏着潜力巨大的矿产资源，为在辽阔的国土面积上实现大深度、高精度、广覆盖地球物理探测，开展半航空电磁探测方法与技术研究显得十分必要.本文总结了国内外半航空电磁法的发展现状，重点围绕方法与装备技术等问题进行讨论，并对近年来的最新成果，如：时频协同探测、半航空短偏移距探测、无人机编队观测等新模式，深度学习去噪、多发射源视电阻率定义、拟地震成像等进行了系统分析.最后，对半航空电磁法的发展方向进行了展望，指出任意码形大功率发射和三维高分辨成像等方法技术是下一步的关键突破方向，有望在深部地质找矿、灾害预警和城市地下深部勘查等方面发挥重要作用.

Abstract:The latest metallogenic theory research and deep positioning prediction results show that there are huge potential mineral resources in the depth of 2000 meters in the mainland of China. In order to achieve a large depth and efficient geophysical exploration coverage in the vast land area, it is necessary to carry semi-airborne electromagnetic exploration methods and technology research. In this paper, we first sort out the development of semi-airborne electromagnetic method at home and abroad, focus on the discussion of methods and equipment technology, and systematically sum up the latest achievements in recent years, such as: time-frequency cooperative detection, semi-airborne short offset detection, UAV formation observation, deep learning denoising, multi-source apparent resistivity definition, pseudo seismic imaging, etc. Finally, the development direction of semi-airborne electromagnetic method is prospected, and the key breakthrough directions of arbitrary code shape high-power emission and three-dimensional high-resolution imaging method are summarized, which is expected to provide more powerful technical support for solving the hot development problems in deep geological prospecting, disaster early warning and urban deep underground exploration in China.
