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 …

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…

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

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 …

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 …

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 …

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.

Jul 11, 2023 · ANFO stands for Ammonium Nitrate Fuel Oil, a powerful explosive compound widely used in various industries, including mining, construction, and quarrying. This article will …

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 …
