Abstract


With China 's rapid economic development , the traditional iron ore resources are increasingly scarce, a considerable part rely on imports, an urgent need to find and develop non-traditional iron ore resources . Hebei and other regions of the ultra- poor magnetite rich resources. However, China still lacks find and develop iron ore resources in non-traditional data , there is no corresponding geological exploration . How to identify , development and utilization of this resource , is placed in front of us an important issue. Induced polarization method studied in the current method is more mature, but also a multi-metal mineral and water resources more effective geophysical exploration techniques . Its device selection diverse, with many physical parameters provided , reflecting the geoelectric information-rich , but in the interpretation of multiple solutions exist , many factors and other characteristics. In this paper, induced polarization theory, through simulation experiments on induced polarization secondary field more in-depth research, the main effects of different media , the whole space , half- space conditions secondary field distribution of each parameter . First, the use of outdoor soil bin simulation methods to accomplish the same geological background conditions with different electrode distance detection ; same electrode under the same conditions at different overburden thickness induced polarization detection . Quantitatively obtained half-space , all space conditions the apparent resistivity , depending on the polarization conversion relationship . Secondly , the use of indoor simulation accomplish the same media , the same electrode spacing different humidity conditions to detect ; same electrode under the same conditions different from the mineral content of the conductive probe induced polarization method . Analysis and comparison of results of different conductive mineral content and apparent resistivity , depending on the polarization of the quantitative relationship , obtained secondary field as the polarization decay law and the conductive mineral content of exponential function . When you reach the ultra- poor magnetite can be taken when the cut-off grade , exponential factor should be greater than a 2.31 ​​. Finally, the inversion maps in a variety of macro- qualitative analysis , based on the optimization of the use of data obtained as the metal element parameters, and use the data fitting results can be taken over lean magnetite ore grade boundary conditions , as the metal elements should be greater than 0.35 (1 /? · m). In combination with other parameters established discriminant model orebody .
