摘要:
近年来，随着地质勘查领域对深部与隐伏矿体探索需求的日益增长，电磁法设备，尤其是从V8电法工作站到广域电磁测深设备的广泛应用，显著推动了攻深找盲工作的进程。基于V8电法工作站与广域电磁测深设备在基本原理及野外作业流程上的高度相似性，创新性地提出了将V8电法工作站采集的可控源音频大地电磁测深数据进行广域化处理的方法。通过对比分析3个实际项目的数据处理结果发现：这一处理策略能够有效模拟并达到广域电磁法设备的勘探效果，实现了在不增加额外硬件投资的前提下，提升了数据解释精度与勘探目标深度。可控源音频大地电磁测深数据的广域化处理方法，不仅是对传统电磁勘探技术的一次重要改进与创新，更是矿山勘查领域新质生产力发展的生动体现。

Abstract:
In recent years,the growing demand for deep and concealed orebody exploration in the geological prospecting field has significantly advanced the process of deep-targeting exploration through the widespread application of electromagnetic equipment,particularly the transition from the V8 electrical workstation to wide-area electromagnetic sounding devices.Based on the similarities in fundamental principles and field operation procedures between the V8 electrical workstation and wide-area electromagnetic sounding equipment,this study proposes an innovative method for wide-area processing of controlled-source audio magnetotelluric (CSAMT) sounding data collected using the V8 electrical workstation.Comparative analyses of data processing results from 3 real cases demonstrate that this approach effectively simulates and achieves the exploration performance of wide-area electromagnetic equipment.It enhances data interpretation accuracy and exploration target depth without requiring additional hardware investment.The wide-area processing method for CSAMT data represents a significant improvement and innovation in traditional electromagnetic exploration technology and exemplifies the development of new quality productive forces in the field of mineral exploration.
