摘要
Resources potential in old mine’s depth and edge prospection is enormous. During the prospecting of nonferrous and precious metal minerals, such as Fe, Pb, Zn, Cu which are related to magnetic mineral in old mine’s depth and edge, the normal, economical and effective methods are high-precision magnetic survey, aeromagnetic survey, magnetic logging, 3D quantitative inversion and joint inversion of surface and borehole. During the prospecting, forward is used on existed ore bodies according to magnetic data to find out residual magnetic abnormality, and then inversion is applied to determine occurrence and depth of ore bodies in old mine’s depth and edge.
