Abstract

This study aims evaluated limestone blasting geometry under massive and blocky rock-mass conditions and developed geometry adjustments to improve fragmentation control. Thirteen production blasts conducted at PT Semen Padang during April–May 2025 were analyzed quantitatively. Fragmentation was predicted using Kuz-Ram and verified against field fragmentation measured using Split Desktop 2.0.1, with X50 and boulders ≥50 cm as evaluation criteria. Actual boulder percentages for massive rock were 67.47% and 69.00% using Kuz-Ram and Split Desktop, respectively, whereas blocky rock yielded 44.89% and 56.00%. Kuz-Ram evaluation of the proposed geometry reduced X50 from 78.05 to 31.29 cm in massive rock and from 46.41 to 26.56 cm in blocky rock. These findings indicate that rock-mass-specific geometry adjustments can improve predicted fragmentation; however, field validation is required before operational implementation.
