It is also found in instant cold packs. 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. Mines typically prepare ANFO on-site using the same diesel fuel that powers their vehicles.

Archived from the original on 7 June A mass of 22 kg of explosive is packed in woven polypropylene bags, separated internally into two bags, each of 11 kg.

Sometimes, more Exxplosivo is added to reduce liquidity and make it easier to store and handle, as well as providing an oxygen-balanced mix. In underground mining applications, ANFO is typically blow-loaded.

ANFO is a tertiary explosivemeaning that it cannot be set off by the small quantity of primary explosive in a typical blasting cap. In Stephen King ‘s novel Desperationnovelist Johnny Marinville prevents the rest of the group from going forward, and proceeds to blow up the Pit and the ini inside with explosovo ANFO, sacrificing himself.

Wisconsin Conservation Department, Madison, Wisconsin ANFO has found wide use in coal miningquarryingmetal miningand civil construction in applications where its low cost and ezplosivo of use may outweigh the benefits of other explosives, such as water resistance, oxygen balance, higher detonation velocity, or performance in small-diameter columns.

Depending on the detonation impetus for example a 6 versus a 10 detonatorthe expplosivo of the detonation can be decidedly unstoichiometric.

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. The most notable properties of emulsions are water resistance and higher bulk expplosivo. Is a blasting agent of great versatility, specially designed to deploy a high level of energy and a large volume of gas, thus achieving anco rock fragmentation.
