| dc.description.abstract | This research aims to map the boundaries of limestone (top limestone) in the mine area 3 PT Semen Baturaja Tbk, Ogan Komering Ulu Regency, South Sumatra Province. using dipole-dipole configuration. The research was conducted on 33 tracks with 29 drilling points, the track length varied between 540, 550, and 560 meters, and the distance between electrodes was 10 meters. The results of the analysis show that limestone is found in almost every measurement point in the 33 passes with thicknesses varying from 5 to 100 meters, characterized by resistivity values of 30 Ωm - 1000 Ωm. The distribution of top limestone depth values (well log) ranges from 1.7 to 34.1 meters, with the distribution of shallow depths in the west to northwest, while the deepest values are in the southwest to northeast. Interpolation results using the resistivity inversion value approach show a depth range of 2.5 meters to 80 meters. The shallowest depths are in the west to northwest direction, while the deepest depths are in the southwest to northeast direction. These findings show a significant distribution, with the interpolation of resistivity depths providing a more accurate picture. Areas with shallow depths may indicate the presence of potential exploration areas for economic limestone resources. This finding can be a reference for related industries in planning limestone exploration and production. | en_US |
