APPLICATION OF GEOELECTRIC METHOD FOR ENVIRONMENTAL STUDY OF GROUNDWATER APPEARANCE IN COAL MINE AREASiti Sailah, Eddy Ibrahim, Dedi Setiabudidaya and M. FaizalAbstract Acid Mine Drainage (AMD) is caused by water flows over or through sulfur-bearing materials forming acidity solutions. The presence of groundwater in overburden layer influences the formation of AMD in contact with sulphide minerals and oxygen. This research was carried out to investigate the presence of groundwater by geophysical approach using 2D geoelectric resistivity measurement with Wenner- Schlumberger array. From 3 measurement lines, line 2 PIT 3 Timur has indication of groundwater appearance. It is shown by resistivity value range between 0.6 to 1 ohm meters. These results could be used by decision makers to carry out coal exploration securely avoiding contact between groundwater and rain water with sulphide minerals and oxygen.
