Ammonium nitrate-fuel oil mixture is commercially available as pale white, gray, yellow, or pink oil-covered prills with a petroleum odor. Non-commercially produced forms may be darker in color. It is used for blasting rock and in some types of mining. It will accelerate the burning of combustible materials. The ammonium nitrate is soluble in ...
ANFO  (or AN/FO, for ammonium nitrate / fuel oil) is a widely used explosive mixture. The oil used is most often No. 2 fuel oil, or diesel fuel, but sometimes kerosene, coal dust, or even molasses. ANFO under most conditions is considered a high explosive; it decomposes through detonation rather than deflagration and with a high velocity.
Explosives - ANFO (Ammonium Nitrate - Fuel Oil) On 10 November 2009 International troops and Afghan police seized 250 tons of ammonium nitrate fertilizer in the southern city of Kandahar.
Ammonium nitrate is a chemical compound, the nitrate salt of the ammonium cation.It has the chemical formula N H 4 N O 3, simplified to N 2 H 4 O 3.It is a white crystal solid and is highly soluble in water. It is predominantly used in agriculture as a high-nitrogen fertilizer. Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction.
Ammonium nitrate fuel oil (ANFO) is a blasting agent that consists of porous prilled ammonium nitrate and fuel oil. When combined with oxygen, it is one of the safest and most affordable blasting chemicals available in the coal mining, quarrying, metal mining and civil construction industries.
4/10/2010 Fuel oil can also be poured onto the ammonium nitrate in approximately the correct proportions as it is poured into the blasthole. For this purpose, about i gal of fuel oil for each 100 lb of ammonium nitrate will equal approximately 6 percent by weight of oil.
Other articles where ANFO is discussed: explosive: Ammonium nitrate–fuel oil mixtures: In 1955 it was discovered that mixtures of ammonium nitrate and fine coal dust would give very satisfactory blasting results in the large (about 22.5-centimetre, 9-inch) holes used in open-pit coal mines to remove the rock and soil covering the coal.
How Do Fertilizer Bombs Work? ... detonation wave radiates outward from the detonator at a speed of about 2 to 3 miles per second through the mixture of ammonium nitrate and fuel, Goodpaster said. ...

ABSTRACT The Bureau of Mines has carried out experimental and theoretical studies with prilled and pulverized ammonium nitrate-fueloil (AN-FO) mixtures contain ing varying amounts of fuel oil in an attempt to quantify the ...
20/1/2018 The purpose of the fuel oil is two fold. Mainly it’s to transmit shock, and for that, any liquid will do. A common blasting explosive is a slurry of ammonium nitrate in a watery gel, which for larger operations arrives in a tanker truck and is pum...

4/12/2011 The normal ratio recommended is 2 U.S. quarts of fuel oil per 50 pounds of ammonium nitrate (80 ml/kg). In practice, a slight excess of fuel oil is added, i.e., 2.5 to 3 quarts of fuel oil per 50 pounds of ammonium nitrate, as underdosing results in reduced performance while overdosing merely results in more post-blast fumes.

explosives such as Ammonium Nitrate and Fuel Oil (ANFO). In this study, the effect of reaction zone ﬂow di-vergence on ANFO detonation was explored through variation of the inert conﬁnement and explosive diameter in the rate-stick geometry with cylinder expansion experiments. New tests are discussed and compared to prior experiments.

9/10/2012 ANFO (or Ammonium Nitrate/Fuel Oil) is a widely used bulk industrial explosive mixture in mines and quarry operation. It consists of 94 % porous Ammonium Nitrate (NH 4 NO 3), (AN) that acts as the oxidizing agent and absorbent for the fuel – 6 % number 2 fuel oil (FO), popularly known as High Speed Diesel (HSD). This forms a reasonably ...
Ammonium nitrate fuel oil (ANFO) is a mixture of solid ammonium nitrate and mineral oil. Easy handling allows it to be used safely in mining, stone quarrying, and tunnel construction. The basic reaction during detonation is the decomposition of the hydrocarbon and the ammonium nitrate into CO 2, nitrogen and water.
