Description
Ammonium Nitrate–Fuel Oil (ANFO) – Use in Dry Blastholes
ANFO is a staple in bulk blasting, recognized for its reliability, low cost, and high detonation performance in dry blasthole operations. It provides a safe, low-sensitivity formulation that reduces accidental initiation while offering effective rock fragmentation and controlled energy release.
Market Overview
The use of ANFO continues to grow as mining, quarrying, and civil engineering sectors prioritize safe, efficient, and scalable bulk explosives. ANFO supports predictable energy output, minimizes operational risks, and meets international regulatory standards. For detailed guidance on ANFO blasting and energy optimization ↗.
