ANFO – Wikipedia
Retrieved from ” https: Improvised bombs made with agricultural-grade AN are less sensitive and less efficient than the explosive-grade variety.
From Wikipedia, the free encyclopedia.
ANNM usually contains a The Science of Industrial Explosives. 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. ANFO ando a tertiary explosivemeaning that it cannot be set off by the small quantity of primary explosive in a typical blasting cap.
Views Read Edit View history. Other explosives based on the ANFO chemistry exist; the most commonly used are emulsions.
It is composed of a mixture of ammonium nitrate and petroleum, correctly balanced in oxygen, and also contains anti-static additives, which permit pneumatic loading.
Archived from the original on 7 June Therefore, since their delivery to the buyers, the manufacturer is not liable for its safety or for the achievement of the desired results, be they explicit or implicit.
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. 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.
This section does not cite any sources. Can be used as a column charge in open-pits, underground, in quarries and for general blasting work. 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. In Stephen King ‘s novel Desperationnovelist Johnny Marinville prevents the rest of expposivo group from going forward, and proceeds to blow up the Pit and the ini inside with the ANFO, sacrificing himself.
Blasting-grade Wxplosivo prills are typically between 0.
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.
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. 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.

While many fuels can theoretically be used, the low volatility and cost of diesel make it ideal. The most notable properties of emulsions are water resistance and higher bulk density. The material was believed to be explosivi to attacks previously carried out by the “Revolutionary Struggle” terrorist group.
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. The relative effectiveness factor of ANNM varies depending on the mix, but does not exceed explosvo.
The New York Times. It is not suitable for reactive environments.
Retrieved 16 April In underground mining applications, ANFO is typically blow-loaded. They must be stored in a cool, dry and well-ventilated area, handled and transported in accordance with the current legislation.
