EMULSION EXPLOSIVES
Emulsion based explosive/ Emulsion is the most recent discovery in explosives industry & is extensively used for commercial blasting all over the world since they are more efficient, more safe & deliver better performance than slurries. It is an aqueous phase of soluble oxidiser salts (e.g. ammonium nitrate) dispersed in an oil phase using an emulsifying agent. The basic composition would be of ammonium nitrate, water, oil & a surfactant. Adding materials such as sodium nitrate waxes, gas bubbles, micro balloons, etc helps in sensitising. These added substances may change edges for response, however, they don't change the fundamental risk attributes of the emulsion.
There has been a significant rise in the usage of emulsion explosives due to greater advantages as compared to other explosives.
The emulsion is stable and does not explode in the standard striking tests or while burning, however, it can explode if it is in contact with materials as detonators, dynamites or aluminum powder.
SAFETY
-
More efficient
-
Increased safety in manufacturing, transporting, storage and handling: The emulsion is classified as an oxidizer, so transport and storage does not lead to danger of explosion. It becomes an explosive when pumped in the borehole
-
Excellent resistance to water
-
Increased velocity of detonation
-
High VOD & weight strength
-
Lowers the emissions of gases (carbon & nitrogen)
-
Savings in drilling operations
-
Priming and coupling made easy
-
Low sensitivity to heat
-
High viscosity and rigidity
