ANFO is technically a high explosive in that it decomposes through detonation rather than deflagration at a velocity higher than the speed of sound in the material, but the low sensitivity means that it is not …

May 6, 2025 · ANFO has some characteristics not shared by other commercial explosives – its critical diameter and detonation velocity can both be varied depending on how it is used.

ANFO (Ammonium Nitrate/Fuel Oil) is a widely used bulk industrial explosive mixture. It consists of 94% porous prilled ammonium nitrate (NH4NO3) (AN) that acts as the oxidizing agent and absorbent for …

When filled with ANFO, a blasthole 400 mm (about 16 inches) in diameter and 7.5 metres (about 25 feet) deep can develop about one billion horsepower. It is incumbent upon those involved in…

Although ANFO has zero water resistance, it has a wide variety of applications in dry hole blasting conditions. It's one of the most cost efficient blasting agents available for use in small, medium or …

Ammonium nitrate-fuel oil (ANFO) blasting agents represent the largest industrial explosive manufactured (in terms of quantity) in the United States.

The chemistry of ANFO detonation is the reaction of ammonium nitrate with a long-chain alkane (C n H 2n+2) to form nitrogen, carbon dioxide, and steam. In an ideal stoichiometric ally balanced reaction, …

In the mining industry, the term ANFO specifically describes a mixture of solid Ammonium-Nitrate prills and diesel fuel. It accounts for an estimated 80% of the explosives used annually in North-America.
