The material was believed to expoosivo linked to attacks previously carried out by the “Revolutionary Struggle” terrorist group. They differ from ANFO in the physical form the reactants take. In Stephen King ‘s novel Desperationnovelist Johnny Marinville prevents the rest of the group from going forward, and proceeds to blow up the Pit and the ini inside with the ANFO, sacrificing himself.
In humid environments, absorbed water interferes with its explosive function. The Science of Industrial Explosives.
Retrieved 3 March With its low sensitivity and excellent performance in breaking and displacing rock, it is ideal for quarries and civil works. Their lower density is due to the presence of a small spherical air pocket within each prill: The press and other media have used the term ANFO loosely and imprecisely in describing improvised explosive devices IEDsin cases of fertilizer bombs see Malicious use below.
ANFO is classified as a blasting agent, meaning that it decomposes through detonation rather than deflagration at a velocity higher than the speed of sound in the material but cannot be detonated with a No.
Retrieved 16 April In an ideal stoichiometrically balanced reaction, ANFO is composed of about Finely powdered aluminium in the mixture will sensitise it to detonate more readily. ANFO has found wide use in coal miningquarryingmetal miningand civil construction in applications where its exolosivo cost and ease of use may outweigh the benefits of other explosives, such as water resistance, oxygen ajfo, higher detonation velocity, or performance in small-diameter columns.
Archived from the original on 7 June It is not suitable for reactive environments. The most notable properties of emulsions are water resistance and higher bulk density.
The balanced equation is as follows:. In underground mining applications, ANFO is typically blow-loaded. Retrieved March 3, The relative effectiveness factor of ANNM varies depending on the mix, but does not exceed 1.
ANFO is also widely exlosivo in avalanche hazard mitigation. Unmixed ammonium nitrate can decompose explosively and has been responsible for several industrial disasters, including the Oppau explosion in Germany, the Texas City disaster in Texas Wnfo, Texasthe Ryongchon disaster in North Koreaand the West Fertilizer Company explosion in West, Texas. Five containers of kilos each were used to blow up the Tax Office building in Bastia on 28 February A larger quantity of secondary explosive, known as a primer or a boostermust be used.
While many fuels can theoretically be used, the low volatility and cost of diesel make it ideal. Please help improve this section by adding citations to reliable sources.
In other projects Wikimedia Commons. Can be used as a column charge in open-pits, underground, in quarries and for general blasting work. It is also found in instant cold packs. When used in wet mining conditions, considerable effort must be taken to remove standing water and install a liner in the borehole; it is generally more productive to instead use a water-resistant explosive such as emulsion.

Retrieved from ” https: Examon – P Is a blasting agent of great versatility, specially designed to deploy a high level of energy and a large volume of gas, thus achieving excellent rock fragmentation.
Blasting-grade AN prills are typically between 0. They must be stored in a cool, dry and well-ventilated area, handled and transported in accordance with the current legislation.
In most jurisdictions, ammonium nitrate need not be classified abfo an explosive for transport purposes; it is merely an oxidizer. ANFO is a tertiary explosivemeaning that it cannot be set off by the small quantity of primary explosive in a typical blasting cap.
Light Anfo – Enaex
The fuel component of ANFO is typically diesel, but kerosenecoal dust, racing fuel, or even molasses have been used instead. In the mining industry, the term ANFO specifically describes a mixture of solid ammonium nitrate prills and diesel fuel. Other explosives based on the ANFO chemistry exist; the most commonly used are emulsions.
Mines typically prepare Qnfo on-site using the same diesel fuel that powers their vehicles. ANNM usually contains a In surface mining applications, it is typically augured into boreholes by dedicated trucks that mix the AN and FO components immediately before the product is dispensed.
For other cartridge forms ask EXSA. Recommended for use in dry holes that will remain dry explosivoo detonation. Storage and warranty Kept in its original packaging and stored in normal conditions of temperature and humidity, complying with current regulations, the product is guaranteed for 6 months from its date of manufacture.

These voids are necessary to sensitize ANFO: A Brief History of the Car Bomb. A total of people were killed, and 38 others injured when, within a short time, several ANFO bombs exploded near four apartment buildings.
