In the early mineral exploration, a single geophysical method was used for exploration or drilling. The blindness is relatively large.With the diversity of geophysical interpretation,A single geophysical method cannot achieve an accurate interpretation of anomalies, It is impossible to judge the characteristics of tectonic belts accurately, According to the geophysical prospecting method of single hole arrangement, The evidence is inadequate? The low rate of mine drilling, Due to relatively large economic waste and delay the construction period?A mining area in Northeast China was first mined in 1959, 50 years later become a crisis mine?In order to alleviate the problem of follow-up resources in mining area,To maintain the sustainable development of the mine, Geophysical prospecting for comprehensive prospecting is carried out in the periphery of the mining area?This text takes a crisis in Northeast mine as an example,The research work of using various geophysical methods to mine is demonstrated?First of all, the aeromagnetic anomaly results are used, To determine the mineralization favorable zone?Then using the pseudo random scanning electrical work, The distribution range of IP anomaly delineated roughly ?The use of IP sounding and gravity profile of work, It shows the distribution pattern and the deep extension of the fracture zone of the bedrock fault?According to gravity, magnetic and electrical prospecting, the metallogenic belts can be effectively divided, And through the drilling verification, Chalcopyrite and pyrite are mined?The method of comprehensive geophysical prospecting is adopted in mining area,The results of mining exploration and the best combination method are summarized?The metallogenic tectonic belt can be divided more accurately, Effectively determine the center position of the drill hole, With guidance or reference for investigation of the similar mines in the future.
