Enhancing mine energy efficiency and productivity necessitates the implementation of
longer ore passes, exceeding 300 m, to optimise material transport in underground mass …

Rock fragmentation is vital in a sublevel caving operation. The oversize fragments are the
most undesired fragmentation category because of their challenges; as such, they require …

Variations in rock fragmentation are very likely to occur in a sublevel-caving operation. This
study conducted a comprehensive test in an iron ore mine to monitor rock fragmentation …

Fragmentation analysis is an essential part of the optimization process in any mining
operation. The costs of loading, hauling, and crushing the rock are strongly influenced by the …

Ground vibrations from blasting are one of the main challenges faced by mines located near
populated areas. To confront this challenge, Luossavaara-Kiirunavaara Aktiebolag's …

This research was conducted to evaluate the association of rock fragmentation with different
unit operations of a sublevel caving (SLC) production cycle. Drilling, charging, and blasting …
