Application and exploration of wide-Area electromagnetic method in strongly interfered carbonate rock mining area
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 bod-ies.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.
