dc.description.abstractCoal is considered as a vital energy mix that build the bedrock of energy access and bridge the energy demand gaps between different countries of the world. The search for Coal at an old mine working in Odagbo village is being carried out by artisan miners who indiscriminately dig underground tunnels in search of Coal.This approach is imprecise, laborious, and harmful to miners and may create geohazards that affect the community and potential coal resources.Electrical resistivity imaging was carried out at a mining site in Odagbo village Kogi state, Nigeria. The research aimed to characterize Coal seam within the study area. The study was targeted at determining the resistivity value associated with the Coal seam and the probable depth of the Coal seam. The LUND imaging system consisting of the ABEM Terrameter SAS 4000, electrode selector ES 464, stainless-steel electrodes, multi-core cables, and jumpers were used to acquire the data in this study. The protocol chosen was the dipole-dipole array because of its supreme sensitivity to; resistivity variation below the electrode in each dipole pair, horizontal variation of resistivity, and to 3D structures. Data processing was done using RES2DINV software. The result of the resistivity imaging revealed three layers of earth materials closely related to resistivity values at a depth of about 30 m from the ground surface. The first layer had resistivity values averagely greater than 700 Ωm. The second layer had resistivity values lower than 2200 Ωm. This layer is probably the host of the coal seam. The third layer had resistivity values greater than 700 Ωm. Coal seams are probably more at the North-East of the survey area and the coal seam is suspected to have resistivity values ranging from about 67 Ωm to 549 Ωm and depth varying from 12 m to 25 m.en_US
