Blasting-grade AN prills are typically between 0. In an ideal stoichiometrically balanced reaction, ANFO is composed of about Can be used as a column charge in open-pits, underground, in quarries and for general blasting work.
The Shijiazhuang bombings Chinese: Retrieved from ” https: Principles and Practices of Modern Coal Mining. In many countries, its purchase and use are restricted to buyers who have obtained the proper license.
The balanced anfl is as follows:. AN is highly hygroscopicreadily absorbing water from air. 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.

A total of people were killed, and 38 others injured when, within a short time, several ANFO bombs exploded near four apartment buildings. While many fuels can theoretically be used, the low volatility and cost of diesel make it ideal.

In most jurisdictions, ammonium nitrate need not be classified as an explosive for transport purposes; it is merely an oxidizer.
Its name is commonly pronounced as “an-fo”. Unsourced material may be challenged and removed. November Learn how and when to remove this template message. 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 City, Texasthe Ryongchon disaster in North Koreaand the West Fertilizer Company explosion in West, Texas.
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.
