Ammonium nitrate fuel oil (ANFO) is made of about 94% ammonium nitrate and 6% fuel oil. ANFO is widely used as an explosive in mining, quarrying, and tunneling construction or wherever dry conditions exist.

What are some explosive liquids?

Chemical composition

• Nitroglycerin: A highly unstable and sensitive liquid.
• Acetone peroxide: A very unstable white organic peroxide.
• TNT: Yellow insensitive crystals that can be melted and cast without detonation.

Why are explosives used in coal mining?

Explosives used in coal mines have to be efficient in blasting rock and coal but at the same time should not ignite the flammable atmosphere that can sometimes be encountered underground. When used, the explosives are placed in drilled holes and shot in rounds, with a short delay between each shot.

Which explosives are used for primary mines and demolition explosive?

TNT is stable and is often combined with RDX and other explosives to make military grade demolition charges. TNT is commonly used for blasting and demolition.

Is Sulphur used in explosives?

Are explosives used in underground mining?

High explosives are used in a few small underground operations where geologic conditions and drilling characteristics require its use. Lawrence Livermore National Laboratory (LLNL) and the U.S. Bureau of Mines, Minerals Availability Field Office (MAFO).

Why do miners use explosives?

The nature of the orebody and mining environment necessitates the use of explosives as a rock-breaking mechanism, thus making explosives an integral part of the mining cycle. Without them, production cannot take place.
