The purpose of this research work is to delineate the strike direction of a coal deposit at Tai area of Gombe, Northeastern Nigeria using a 2-D electrical resistivity method. ABEM Terrameter SAS 1000 was used for the data acquisition. Wenner-Schlumberger array protocol was employed because of its large median depth of investigation and slightly better horizontal coverage. Data processing was done using RES2DINV software and the result shows that there is continuity of geological structure. The study reveal that the suspected coal seam in profile 3 and 9 taken in Northeast-Southwest (NE-SW) direction showed a clearer picture of the suspected coal seam because the profiles were laid perpendicular to the strike direction while that of profile 2 and 4 taken in Northwest- Southeast (NW-SE) direction was not pronounced because the profile was laid along the strike direction. Hence it can be concluded that the coal seam is striking in the NW-SE direction, and therefore for any future research to ascertain the coal reserve of the area, profiles should be laid in Northwest-Southeast direction in order to obtain an optimum result.
