ANFO (/ ˈ æ n f oʊ / AN-foh) [1] (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial high explosive. It consists of 94% porous prilled ammonium nitrate (NH 4 NO 3 ) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO). [ 2 ]

ANFO Explosive – A Versatile Solution Ammonium Nitrate is an adaptable oxidizer that works well when explosions are needed during mining or quarrying operations. When combined with fuel oil, it makes an effective explosive that has a wide range of applications.

Excerpt from ERG Guide 112 [Explosives - Division 1.1, 1.2, 1.3 or 1.5]: IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area immediately for at least 500 meters (1/3 mile) in all directions. LARGE SPILL: Consider initial evacuation for 800 meters (1/2 mile) in …

Ammonium nitrate-fuel oil (ANFO) blasting agents represent the largest industrial explosive manufactured (in terms of quantity) in the United States. This product is used primarily in mining and...

In this review, we summarised the most relevant recent developments in ANFO supplementation aimed at improving ANFO detonation properties and at eliminating the problems related to nonideal detonation.

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… Read More

Aug 5, 2020 · Mixed with fuel oil it’s known as ANFO (ammonium nitrate/fuel oil), which accounts for approximately 80% of the 2.7 billion kilograms of explosives used in North America every year. In these explosive mixtures, it acts as an oxidising agent, helping other materials burn.

Oct 1, 1995 · ANFO is an acronym for the most popular blasting agents in use today. It stands for ammonium nitrate, fuel oil; and it is a simple mixture of the two.

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 delve into the basics of ANFO, its composition, properties, and common applications.

Aug 16, 2019 · Under certain conditions, ANFO could be initiated with primers no more powerful than a No. 8 blasting cap. It is the nature of ANFO to demonstrate transient velocities upon initiation from any primer or booster.
