ANFO under most conditions is blasting cap —insensitive, so it is classified as a blasting agent  and not a high explosive. When used in wet mining conditions, considerable explowivo 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.

ezplosivo Please help improve this article by adding citations to reliable sources. In an ideal stoichiometrically balanced reaction, ANFO is composed of about Retrieved from ” https: The balanced equation is as follows:.
Their lower density is due to the presence of a small spherical air pocket within each prill: November Learn how and when to remove this template message.
Ammonium nitrate is widely used as a fertilizer in the agricultural industry. Mines typically prepare ANFO on-site using the same diesel fuel that powers their vehicles. ANFO is a tertiary explosivemeaning that it cannot be set off by the small quantity of primary explosive in a typical blasting cap.
In practical use, such conditions are impossible to attain, and blasts produce moderate amounts of toxic gases such as carbon monoxide and nitrogen oxides NO x. A mass of 22 kg of explosive is packed in woven polypropylene bags, separated internally into two bags, each of 11 kg. AN is highly hygroscopicreadily absorbing water from air.
Other explosives based on the ANFO chemistry exist; the most commonly used are emulsions. Unmixed ammonium nitrate can decompose explosively and has been responsible for several industrial disasters, including the Oppau afno in Germany, the Texas City disaster in Texas City, Texasthe Ryongchon disaster in North Koreaand the West Fertilizer Company explosion in West, Texas.
Principles and Practices of Modern Coal Mining. 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.

In most jurisdictions, ammonium nitrate need not be classified as an explosive for transport purposes; it is merely an oxidizer. It is also found in instant cold packs. Recommended for use in dry holes that will remain dry until detonation. ANFO is also widely used in avalanche hazard mitigation.
ANFO You have doubts? This page was last edited on 1 Decemberat ANFO is classified as a blasting agent, meaning that it decomposes through detonation rather than explosvio at a velocity higher than the speed of sound in the material but cannot be detonated with a No. The use of ANFO originated in the s. Retrieved 3 March 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.
