While empirical rock fragmentation models are easy to parameterize for blast design, they
are usually prone to errors, resulting in less accurate fragment size prediction. Among other …

A model for fragmentation in bench blasting is developed from dimensional analysis
adapted from asteroid collision theory, to which two factors have been added: one …

The Mine-to-Mill (M2M) approach aims to enhance efficiency and reduce costs in the
mineral processing industry by optimizing the mining and processing stages. M2M …

The optimum fragmentation size measures the quality of a blasting operation. Boulders or
large fragments can result in more costs because they need secondary blasting, while small …

This research introduces an innovative technique for estimating the particle size distribution
of muckpiles, a determinant significantly affecting the efficiency of mining operations. By …

The optimization of blasting operations greatly benefits from the prediction of rock
fragmentation. The main factors that affect fragmentation are rock mass characteristics, blast …

Burden movement plays very important role in the bench blasting for the effective utilization
of the explosive energy. The optimum burden for a blast face varies with the nature of the …

The mineral industries have shown a significant shift from openpit to underground method of
mining due to extinction of shallow depth ore deposits. The openpit mining is preferred for …

Purpose. The research aims to investigate the impact of discontinuity characteristics,
including dip direction, dip and joint spacing, on the size distribution of blasted fragments in …

SYNOPSIS Liqhobong Mining Development Company (LMDC) has been experiencing
problems with boulders after blasting where the fragment sizes exceed the maximum of 800 …
