Physical modeling of the passive induced polarization method for the possibility of estimating the depth of the ore body simulator

The article presents physical modeling data for the passive method of induced polarization for the possibility of estimating the depth of immersion of the ore body simulator. Experimental observations were carried out on a laboratory tank filled with sand, the observation time for each measurement point was 180 s, the sampling frequency was 1 kHz. In the course of physical modeling, measurements of the induced polarization parameter were carried out in the absence of an ore body simulator, with its immersion by 10 cm and 20 cm, as well as with full immersion and immersion to a depth of 30 cm. As a result of physical modeling with an ore body simulator, the following results: the dependence of the induced polarization parameter was obtained with increasing depth; with increasing depth, the change in the induced polarization parameter decreases; the background value of the induced polarization parameter in the absence of an ore body simulator leads to a decrease in the sensitivity of the measurement equipment.
