Flyrock in surface miningāPart 3: Shock wave, stress wave, blasthole expansion
The generally accepted view in rock blasting is that the sources of energy for the fracture andĀ movement of rock reside in the shock wave and gas action resulting from the explosion, and yetĀ the mechanisms by which these sources interact with the rock have remained unclarified. Ā Ā
Flyrock in surface mining Part II ā 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 distancesĀ 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 ā 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 […]
