Due to the importance of pollution and adverse consequences on ecosystems and human life, in this study, in the area of Zailik mine in NW Iran, in order to determine the range of changes in Geoelectrical resistivity of faults with crushed zone containing fluid potential in the study area and separation of subsurface layers based on their electrical resistance, sounding Electrical transmitters with a maximum length 500 meters has been designed and run.
The results of analysis and modeling of 24 soundings have shown that in three faults there is permeability potential or typical faults with crushed zones with fluid and in the rest of the faults the fluid passage potential is not specified.
Also, the permeability changes calculated with the geoelectric obtained from geophysical experiments, depots in contour map, have shown that the dominance with permeabilities less than 4 and in fact the impermeability of the foundation stone is the location of the depots. Therefore, it is expected that the infiltration of surface water and possible contaminants from the surface into the seams and crevices as well as spring water will be zero.
In fact, the high geoelectric resistance of these rocks indicates their impermeability, which indicates a suitable floor stone from an environmental point of view and reduces the possibility of contamination escaping through seams and fractures to zero. Similarly, in zones 1 to 3 of the mining, a major fault that indicates the permeability and the probability of passage and transmissibility of the fault is not detectable.
