Drilling and blasting in quarries: what is specific
Why steady fragmentation and a rhythm for the crusher matter in a quarry.
In a quarry it is not one lucky shot that matters, but a steady result from blast to blast.
What matters
- Consistent fragmentation for the crusher
- Even supply of material
- Vibration control at the quarry boundary
A steady blast reduces over-crushing and oversize, saving on crushing and loading.
