ANFO explosive is often preferred because using bulk explosives is cheaper, less labor intensive during loading and they fill the entire blast hole diameter. Emulsion explosives should not be used in strong and massive rocks where a high detonation pressure and high detonation velocity is required to break the rock. During rock fragmentation by blasting, the reflection of the compression wave at the free face into tension and shear waves contributes to additional cracking between the free face and the blast hole. When metals or other reactive elements are present in the composition of an explosive, less oxvgen is required for a an oXvgen-balanced reaction.

ANFO explosive is often preferred because using bulk explosives is cheaper, less
labor intensive during loading and they fill the entire blast hole diameter.
Emulsion explosives should not be used in strong and massive rocks where a
high detonation pressure and high detonation velocity is required to break the
rock.
During rock fragmentation by blasting, the reflection of the compression wave at
the free face into tension and shear waves contributes to additional cracking
between the free face and the blast hole.
When metals or other reactive elements are present in the composition of an
explosive, less oxygen is required for a an oxygen-balanced reaction.
