In underground mining applications, ANFO is typically blow-loaded.
This section does not cite any sources. These voids are necessary ex;losivo sensitize ANFO: In the movie The Dark Knight by Christopher NolanThe Joker uses qnfo compound to hold two ferries hostage, and tries to make the people on each ferry detonate the other ferry.
The use of ANFO originated in the s. The material was believed to be linked to attacks previously carried out by the “Revolutionary Struggle” terrorist group. Sometimes, more AN is added to reduce liquidity and make it easier to store and handle, as well as providing an oxygen-balanced mix.
ANFO – Wikipedia
Storage and warranty Kept in its original packaging and stored in normal exploaivo of temperature and humidity, complying with current regulations, the product is guaranteed for 6 months from its date of manufacture. Finely powdered aluminium in the mixture will sensitise it to detonate more readily. Improvised bombs made with agricultural-grade AN are less sensitive and less efficient than the explosive-grade variety.
In most jurisdictions, ammonium nitrate need not be classified as an explosive for transport purposes; it is afno an oxidizer. A Brief History of the Car Bomb.
ANFO is also widely used in avalanche hazard mitigation. ANFO You have doubts? November Learn how and when to remove this template message.
Retrieved 28 July Views Read Edit View history. 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 anco used the substance in bomb attacks.
A larger quantity of secondary explosive, known as a primer or a boostermust be used.

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.

Its name is exlosivo pronounced as “an-fo”. Can be used as a column charge in open-pits, underground, in quarries and for general blasting work. Their lower density is due to the presence of a small spherical air pocket within each prill: In practice, a slight excess of fuel oil is added, as underdosing results in reduced performance while overdosing merely results in more post-blast fumes.
AN is highly hygroscopicreadily absorbing water from air.
Other explosives based on the ANFO chemistry exist; the most commonly used are emulsions. Preferred use is in well-ventilated places. While many fuels can theoretically be used, the low volatility and cost of diesel make it ideal. ANFO under most conditions is blasting cap —insensitive, so it is classified as a blasting agent  and not a high explosive.

The most notable properties of emulsions anfi water resistance and higher bulk density. 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. They differ from ANFO in the physical form the reactants take.
Examon – P Is a blasting agent of great versatility, specially designed to deploy a high level of energy and a znfo volume of gas, thus achieving excellent rock fragmentation. For other cartridge forms ask EXSA.
