چکیده مقاله:

Various problems caused by the presence of groundwater in Area No١ of Gol-e- Gohar iron ore mine, have made mining experts seek appropriate methods for preventing the flow of groundwater into the mine pit. Due to the expected negative influence of subsurface water on the mining activities in Area No٣ of this mine, a suitable drainage system should be designed and established before commencement of mining activities. Geoelectrical investigations using resistivity method were carried out in the area to determine groundwater conditions in the area. Twenty five resistivity soundings with maximum electrode spacing of 1400m were performed in the area A square grid of 500*500m was set up to cover the whole area. One-dimensional interpretation of the sounding data showed the depth to water table to be 40-60 m with an average thickness of 26-35m for the water-bearing formation. It was also inferred from the sounding data interpretations that the resistivity of the water-bearing formation was in the range of 12-26Ωm indicating high electrical conductivity of groundwater, interpreted to be due to high salinity and concentration of total dissolved solids (TDS) in the groundwater.dggg
