Abstract: This study aims to calculate coal volume in the Run of Mine (ROM) area at PT Victor Dua Tiga Mega using Geodetic GPS and the cut and fill method. Geodetic GPS measurements produced 2,016 elevation points, which were processed into contours with a 1-meter interval and a Digital Elevation Model (DEM). Volume calculation was performed by comparing the initial and final surface models to determine elevation differences (ΔZ) across the stockpiles. The total calculated volume was 170,915.146 m3, which was converted to tonnage using a coal density of 0.96 ton/m3, resulting in 164,078.540 tons. Compared to the weighing data of 160,766.433 tons, the deviation was 2%, within ASTM’s 2.78% tolerance. The results indicate that Geodetic GPS provides accurate, efficient, and reliable measurements for coal volume estimation, offering significant time and cost savings while maintaining high precision for large-scale mining operations.
