Introduction As part of continuous improvement efforts to optimise blasting performance and enhance safety at Gold Operation X, engineering trials were designed to trial the
When your blast outcomes are inconsistent, the problem is often not the explosive. It may be based on blast design, and whether the energy is
Your choice of stemming plug is specific to your operation’s needs. On some blasts, your biggest win comes from tightening collar confinement and cutting flyrock
Blasts that lose containment energy drive up costs. The stemming plug you choose directly impacts how productive each blast becomes. We compare Varistem and Max-Blast
Your choice of stemming plug is a significant decision for mining and blasting consumables. You might be fighting flyrock on sensitive benches, or trying to
Blasts that lose energy retention result in additional costs, uneven breakage, noise, and increased drilling and explosives. The choice in your stemming device dramatically impacts
In blasting, every metre of advance and every ton of ore or aggregate matters. Mines, quarries, and construction crews face daily challenges: uneven breakage, flyrock,
Introduction Pre-split blasting is a vital controlled blasting technique used in surface mining, quarrying and construction operations to preserve the stability of final pit walls,
