Coal Layer Identification using Electrical Resistivity Imaging Method in Sinjai Area South Sulawesi

The purpose of this research is to image subsurface resistivity for coal identification in Panaikang Village, Sinjai, South Sulawesi.Resistivity measurements were conducted in 3 lines of length 400 meters and 300 meter using resistivity imaging, dipole-dipole configuration. Resistivity data was processed using Res2DInv software to image resistivity variation and interpret lithology. The research results shown that coal resistivity in Line is about 70-200 Omega m, Line 2 is about 70-90 Omega m, and Line 3 is about 70-200 Omega m with average thickness about 10 meters and distributed to the east of research area.
