    Best Practices In Drill And Blast

    Under-blasting can lead to signi cant amounts of oversize rock which cannot pass through the crusher and will require size reduction before being taken to the crusher. Conducting fragment break-up is costly and needs secondary blasting or use of a mechanical hammer for rock disintegration. UNIQUE FACTORS THAT INFLUENCE FRAGMENTATION
