| 地空瞬变电磁探测技术融合了地面电磁方法和航空电磁方法的优势，具有高效率和大深度探测的优势，近年来受到广泛关注。本文针对国内资源勘探中复杂地形地貌条件下传统瞬变电磁探测工作难度大、效率低等瓶颈问题，研发了地-空瞬变电磁全域视电阻率定义方法，实现了全时域、全空域的视电阻率计算。同时，研制了地-空瞬变电磁接收系统与大功率的地面发射系统，提高了观测信号的信噪比，加大了探测深度。建立了适用于高山、沼泽等复杂地形条件的地-空瞬变电磁高效观测系统。在陕西某矿区进行应用，取得了较好的应用效果。 |
| 英文摘要: |
| The ground-air transient electromagnetic detection technology integrates the advantages of groundelectromagnetic methods and airborne electromagnetic methods, featuring high efficiency and deep detection capa-bilities. It has received extensive attention in recent years. In response to the bottleneck problems such as high diffi-culty and low efficiency of traditional transient electromagnetic detection work under complex terrain and landformconditions in China's resource exploration, a definition method for the all-domain apparent resistivity of ground-space transient electromagnetic has been developed, achieving the calculation of apparent resistivity in the all-domain and all-domain. Meanwhile, a ground-air transient electromagnetic receiving system and a high-powerground transmitting system were developed, which improved the signal-to-noise ratio of the observed signal and in-creased the detection depth. An efficient ground-air transient electromagnetic observation system suitable for com-plex terrain conditions such as high mountains and swamps has been established.It was applied in a certain miningarea in Shaanxi Province and achieved good application results. |
