APPLICATION OF COMPREHENSIVE GEOPHYSICAL PROSPECTING IN THE DETECTION OF MINED-OUT IRON ORE REGION

It is key to the accurate detection in mined-out iron ore region to choose proper physical prospecting method.In order to find out the spatial distribution of mined-out region, precision magnetic detection is a new test, and the result will be better if other methods are combined.Based on some examples, the application of comprehensive physical method in the detection of mined-out region is introduced.
