The Cost of Optimising in Silos: Why Mining Needs a Whole-of-Value-Chain Perspective
Mining has become exceptionally effective at driving efficiencies within individual functions. Procurement teams negotiate harder. Operations pursue productivity improvements. Processing plants optimise recoveries. Smelters focus on throughput and stability. The challenge, according to AECI Mining, is that the connections between these decisions are not always visible. Yet one of the greatest opportunities for value creation […]

Flyrock in surface mining–Part 3: Shock wave, stress wave, blasthole expansion
The generally accepted view in rock blasting is that the sources of energy for the fracture and movement of rock reside in the shock wave and gas action resulting from the explosion, and yet the mechanisms by which these sources interact with the rock have remained unclarified.
Flyrock in surface mining Part II — Causes, sources, and mechanisms of rock projection
Flyrock can be defined as the throw of rock fragments from a surface or open pit blast that travel distances beyond the expected range or a pre-set safety zone, and which pose a serious threat of damage to property and infrastructure, and injury to people in and around the mine property
Flyrock in surface mining – Limitations of current predictive models and a better alterative through modelling the aerodynamics of flyrock trajectory
In comparison to the propagation and attenuation of ground and airborne vibrations, flyrock is a much less well understood phenomenon. Yet flyrock is often considered to be the most hazardous of the adverse effects of rock blasting in surface mines and construction works. It can damage machinery, property, and industrial structures, as well as cause […]
