Accurate characterisation of material movement during blasting is critical for maintaining grade control and ensuring that extracted material remains within specification. Conventional blast movement approaches typically provide limited representation of displacement in the vertical (Z) direction, instead relying on simplified horizontal vectors or sparse point-based measurements. This limitation is particularly consequential in stratiform mineral systems, including layered mafic intrusions, where mineralisation occurs as laterally extensive, sub-parallel layers with sharp ore waste contacts that are highly sensitive to vertical displacement. In layered mafic intrusions, even modest vertical movement across these contacts can result in significant dilution, ore loss, and misclassification of material during post-blast mark-out and excavation. Misunderstanding the true three-dimensional nature of blast-induced movement therefore represents a material risk to both grade control accuracy and downstream reconciliation. Recent advances in computing power, remote sensing, and data integration have enabled the development of simulation-based tools capable of modelling blast-induced material behaviour in three dimensions. Augment Technologies’ Ore Movement Policy™ (OMP) is an AI-driven 3D blast movement solution that integrates pre- and post-blast surface surveys, drill and blast design data, and the grade control block model to generate a high-resolution Muckpile Block Model™ (MBM) at 1 m3 scale. This paper presents the results of a campaign of high-density ore-waste contact field measurements across five blasts in an operating mine. The results reveal the true nature of material movement due to blasting. Each blast is also simulated and quantitative comparisons are made between field measurements, simulation results and mark-outs. Implications for adopting simulations are discussed including the effect on ore loss and dilution and additional operational benefits enabled by blast movement simulation including personnel safety. Practical strategies to mitigate adverse blast movement impacts are discussed, including a novel change in mark-out practices and the application of dynamic flitch heights.
