A straight ammonium nitrate emulsion provides the greatest water resistance. But ANFO generally provides a better blasting result in quarry applications. This is where blends come in to play. A blend product is a mixture of ANFO and emulsion. When ANFO and emulsion are blended together, the emulsion coats the prills of …

Quarry blasting is the controlled use of explosives to break rock into smaller, manageable pieces for extraction and processing in quarries. This technique is essential for efficiently accessing and removing materials such as stone, gravel, and other aggregates needed for construction and industrial applications.

A blasting agent is a substance or mixture made up of fuel and an oxidizer that is utilized for blasting purposes. It is not, however, classified as an explosive, as some of its ingredients are explosives. When confined, it should not be able to be detonated with a No.8 blasting cap. An example of a blasting agent is the combination of ammonium ...

However, there are several oxidizers that could be considered as possible replacements for ammonium nitrate if needed. After a critical evaluation two possible alternatives are recommended for further study: the use of sodium nitrate as a partial replacement and the development of a new type of blasting agent based upon water as the main oxidizer.
