Image credit: KAZ Minerals Introduction Presplitting is a widely used controlled blasting technique in open-pit mining, aimed at minimizing damage to the remaining rock formation and ensuring greater stability (Pomasoncco-Najarro et al., 2022). By creating a pre-defined fracture line before the main blast, presplitting helps to prevent overbreak and unnecessary rock damage, which is especially […]

Mining methods to control excessive dilution
Mining Doc
Istock Image A common indicator for excessive dilution is the usage of planning “adjustment” factors (mass and/or grade multiplier). These could typically be block model factor (typically grade), mine design factor (typically tonnes and grade), mine call factor / schedule factor (typically tonnes and grade), process factor (typically contained metal), etc. The key to controlling […]
Rock fragmentation analysis using UAV technology
Mining Doc
Why using UAV technology? Accurate measurement of blast-induced rock fragmentation is of great importance for many mining operations. The post-blast rock size distribution can significantly influence the efficiency of all the downstream mining and comminution processes. Image analysis methods are one of the most common methods used to measure rock fragment size distribution in mines […]
Teck Resources decreases copper output projection again.
Mining Doc
Teck Resources, a Canadian miner, exceeded third-quarter profit projections on Thursday, boosted by higher copper production volumes at its Chile mine and robust red metal prices. Copper prices remained high in the quarter, buoyed by confidence about Chinese demand following a slew of stimulus measures from Beijing. The long-term demand outlook for the red metal […]
