What is needed to detonate ANFO?

What is needed to detonate ANFO?

ANFO can deflagrate if a significant amount of water has damaged the ANFO. ANFO can fail to detonate if water has damaged enough ANFO in the hole.

Can you make ANFO?

You blend two to five percent common kerosene, household fuel oil, or diesel fuel with 95 to 98 percent ammonium nitrate, mixing it well. The resulting ANFO is so insensitive to shock that it requires a high explosive such as dynamite to detonate it (as opposed to the slight friction needed to explode black powder).

What is ANFO What is ANFO made out of?

The usual ANFO formulation contains about 94% by weight ammonium nitrate and 6% diesel fuel oil. If recycled (used) lubricating oil could be safely substituted for the fuel oil, up to about 27 million gallons could be consumed. This use of recycled oil (RO) can save energy and reduce oil imports.

Can ammonium nitrate explode without detonator?

Without a detonator, pure ammonium nitrate does not explode, which is why it is considered safe to use as an agricultural fertilizer.

At what temperature does ammonium nitrate explode?

400 degrees Fahrenheit
Ammonium nitrate would only explode on its own if its temperature was rapidly raised to 400 degrees Fahrenheit. Any carbon-rich fuel—paper, cardboard, or even sugar—can pair with ammonium nitrate to produce more intense energy.

Is ANFO a fertilizer bomb?

The most common fertilizer bomb combines AN with fuel oil, to make the compound ANFO. However, an ANFO bomb is still very powerful, and its heaving action can cause significant damage, which is why the compound is used extensively in mining and construction.

Is it possible to detonate ANFO without an explosive detonator?

It occurs when a explosive or oxidizer is lit on fire (deflagration) and at some magical fucking point it detonates. Or it doesn’t. It’s entirely up to the detonation gods. Its pretty much impossible to detonate ANFO without an explosive detonator.

Is there a way to detonate ANFO with a blasting cap?

ANFO cannot detonate with a simple blasting cap. It requires a small to moderate booster charge to fully initiate. Since this is being asked on a public forum, I am assuming your resources and knowledge are fairly limited so I will make this simple. The most cost efficient yet powerful detonator is a TATP/Ammonal.

What makes up thermite in an ANFO bomb?

Thermite is simply an incendiary composition consisting of 2.75 parts of black iron oxide (ferrosoferric oxide) and 1.0 part of granular aluminum. So let’s say it’s not that powerful enough to detonate ANFO, unless there’s some additional booster. For a safe environment and for lawful purposes, explosives should be handled extremely carefull

What’s the difference between ANFO and PETN explosives?

ANFO has the maximum (about six charge diameters) and PETN/TNT explosives have the least (about one charge diameter) as in fig – 1. A VOD less than 2,000 m/s is not considered stable. Tests carried out by Swedish Detonic Research Foundation (SVEDEFO) showed that a NG based explosives primer cartridge initiates ANFO directly to its full velocity.
