The fuel component of ANFO is typically diesel, but kerosenecoal dust, racing fuel, or even molasses have been used instead. Retrieved from ” https: Unsourced material may be challenged and removed.
Five containers of kilos each were used to blow up the Tax Office building in Bastia on 28 February Blasting-grade AN prills are typically between 0. Retrieved March 3, ANFO has found wide use in coal miningquarryingmetal miningand civil construction in applications where its low cost and ease of use may outweigh the benefits of other explosives, such as water resistance, oxygen balance, higher detonation velocity, or performance in small-diameter columns.
AN is highly hygroscopicreadily absorbing water from air.

While many fuels can theoretically be used, the low volatility and cost of diesel make it ideal. Can be used as a column charge in open-pits, underground, in quarries and for general blasting work.
In JanuaryPresident Hamid Karzai of Afghanistan also issued a decree banning the use, production, storage, purchase, or sale of ammonium nitrate, after an investigation showed militants in the Taliban insurgency had used the substance in bomb attacks. ANFO is a tertiary explosivemeaning that explosivp cannot be set off by the small quantity of primary explosive in a typical blasting cap. In humid environments, absorbed water interferes with its explosive function.
ANFO under most conditions is blasting cap —insensitive, so it is classified as a blasting agent  and not a high explosive.
Depending on the detonation impetus for example a 6 versus a 10 detonatorthe products of the detonation can be decidedly unstoichiometric. In other projects Wikimedia Commons. The press and other media have used the term ANFO loosely and imprecisely in describing improvised exploivo devices IEDsin cases of explosio bombs see Malicious use below.
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.
Archived from the original on 7 June 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. Pothole Blasting for Wildlife.
The most notable properties of emulsions are water resistance and higher bulk density. They must be stored in a cool, dry and well-ventilated area, handled and transported in accordance with the current legislation.
Preferred expposivo is in well-ventilated places. Retrieved 3 March Please help improve this section by adding citations to reliable sources. The use of ANFO originated in the s. Their lower density is due to the presence of a small spherical air pocket within each prill: The New York Times.
ANFO You have doubts? It is also found in instant cold packs. Retrieved 28 July A Brief History of the Car Bomb. 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.
From Wikipedia, the free encyclopedia. ANFO is classified as a blasting agent, meaning that it decomposes through detonation rather exploivo deflagration at a velocity higher than the speed of sound in the material but cannot be detonated with a No.
The balanced equation is as follows:.
