中文摘要:
      目前中国各成熟矿山大多面临浅部资源量不足的危机,对深部资源勘探的需求在不断增强。在实际勘探应用中,除了要进行大深度高精度探测,还要克服复杂地形与强电磁干扰的影响,因此对勘探技术提出了更高的要求。本文采用广域电磁法,在地形复杂且电磁干扰严重的云南某碳酸盐岩矿区开展了应用探索研究。结果认为广域电磁法在复杂碳酸盐岩矿区能够有效地压制干扰,对断层和已知矿体反映明显。据此在矿区深部圈定了可能的矿致异常,为矿区深边部找矿提供了指示方向,在复杂地形强电磁干扰的碳酸盐岩矿区开展攻深找盲探矿工作,广域电磁法能够实现高精度大深度探测,抗干扰能力强,工作效率高,可作为一种深部找探矿的技术手段。
英文摘要:
      At present, most nature mines in China are facing the crisis of shallow resources,and the demand for deep resources exploration is increasing. In actual exploration applications, in addition to great depths and high precision detection, it is also necessary to overcome the influence of complex terrain and strong electromagnetic interference, which puts higher requirements on exploration technology. In this paper, wide-field electromagnetic method is used to carry out application exploration research in a carbonate mining area in Yunnan where the terrain is complex and electromagnetic interference is severe. The results show that wide-field electromagnetic method can suppress interference effectively in complex carbonate mining area, and it is obvious to faults and known ore bodies. Based on this, possible mineral anomalies are delineated in the deep part of the mining area, which provides an indication direction for prospecting in the deep edge of the mining area. In carbonate rock mining areas with complex terrain and strong electromagnetic interference, deep exploration and blind prospecting are carried out. The wide-field electromagnetic method can achieve high-precision and large-depth detection, has strong anti-interference ability, and high work efficiency, and can be used as a technical means for deep prospecting.
