Acquisition setup for rock fragmentation measurement in field conditions

Chairul Salam M., Maharani Rindu Widara, Ign Mahendradewa Adam et al. · 2026 · Journal of Engineering and Applied Science

Abstract Rock fragmentation is a key determinant of downstream excavation performance in surface mining operations. Among blasting design parameters, stemming depth governs explosive energy confinement; however, its field-scale influence on fragmentation quality and excavation efficiency remains insufficiently quantified. This study experimentally investigates the effect of two stemming depths (3 m and 4 m) on rock fragmentation characteristics and excavator cycle time through controlled field blasting trials conducted in a hard sandstone formation. All blasts were executed using identical dri
