Application of comprehensive geophysical prospecting method in ore prospecting in coverage area: A case study of integrated survey area of Wuhe Gold Mine in Eastern Anhui

Wuhe area is located in the southern section of Tan-Lu fault zone,and most of the area is covered by the Quaternary and has complex structures. It is difficult to carry out basic geological survey,and no prospecting breakthrough has been made for a long time. In order to obtain geological prospecting information, comoined with regional geological features the authors have used the comprehensive geophysical method to interpret the anomalies, which can screen the mine-induced anomalies effectively and improve the success rate of drilling verification. By carrying out medium and large scale complex geophysical detection, the authors have developed the medium and large scale combination bedrock detection technology for geological structures in the coverage area. And combined with the repeatedly circulation of three or four phases in one selection comprehensive exploration model of the coverage area, the difficulty of finding gold mines in the deep part of the coverage area under complex structural conditions has been overcome and important prospecting achievements have been made. Two medium-sized gold mines and one small-sized gold mine have been found, and the total scale has reached a large size. A major breakthrough in finding gold mines in Tan-Lu fault zone in Anhui Province has been realized. The medium and large scale complex geophysical detection and the repeatedly circulation of three or four phases in one selection exploration model have important significance in the exploration of gold-polymetallic deposits in thick coverage areas.
