High-resolution aeromagnetic exploration methods and their application in daye iron mines

Aiming at the need of looking for ore in the outside of the mine and in the depth of the mine,this paper gives a set of high-resolution aeromagnetic exploration methods,including airborne geophysical survey method with helicopter,transform method for curved surface potential field and precise inversion and interpretation method.Applying the methods to Daye iron mines of Huangshi city,Hubei province,makes a great success.In the year of 2006,rich iron ore and its associated minerals of Cu and Au have been dug up in two of the four drill holes arranged by the interpretation results.Accordingly,the innovation of technique is significant in the work of potential ore digging.
