Study On Digital Simulation Of Surface-borehole IP Method Detection The Blind Ore Body

Surface - borehole IP in mine detection Blind Ore beside the borehole has its unique role. In this paper, Surface-borehole IP method of three-dimensional finite element simulation to study the Blind Ore bodies in boreholes IP response, summed up the boreholes of the IP anomaly and the relative position of blind ore, ore body blind analysis of detection The feasibility, Surface - borehole IP method detection Blind Ore body beside the boreholes and provide a theoretical basis.Numerical simulation of the finite element method, the first field and polarization in the presence of the total field, with equivalent resistance method to calculate - the three electrodes installation of polarization. The occurrence of different high-polarization of the high resistance, low resistance high polarization of the plate borehole IP response of the unusual features of polarization and the corresponding relations. The results show that the - well IP method detection blind ore body is feasible, according to the different position of the well-observed polarization anomaly as a result, abnormal curve of the maximum points corresponding polarization of the location of the use of this method Blind detection of the ore body is beyond the scope of this very great value was not obvious; rock and polarization of the difference between resistance as the impact of polarization, with the rate increasing polarization of resistance, depending on a The rate of abnormal rate will be increased abnormal curve corresponding to the extreme point of the top plate polarization at the same time, depending on the polarization of unusual magnitude of the plate and the polarization is directly proportional to the size, polarization The polarization of the higher rate, the rate of abnormal well as the greater polarization.
