On the IP effect of model sphere buried in simulated landfills.

Abstract In order to identify metal-enriched zone in landfills and utilize valuable metals as urban mining, the resistivity and induced polarization measurements have been carried out as a nondestructive three-dimensional prospecting. The authors conducted an experiment for further improvement of the induced polarization measurement. In the experiment, model spheres consisting of a mixture of cement and iron sulfide, were buried in simulated landfills. We set electrodes on the surface of simulated landfills and measured resistivity and chargeability. The measurements were conducted in the cases of the model with different ratio, electrodes with different materials, the use of wenner or dipole-dipole arrays, and the different intervals of the prospecting lines. As a result, IP anomaly of model spheres buried in simulated landfills could be identified clearly under the use of a carbon rod as electrode, applying the dipole-dipole array, and prospecting line interval of 30 cm.
