The bulk emulsion explosives segment represents the primary volume catalyst within the South American blasting sector. Formulated as a water-in-oil micro-emulsion containing microscopic droplets of ammonium nitrate solution suspended within a continuous fuel oil matrix, these products are inherently non-explosive during transport and storage. They are sensitized only as they are pumped directly down the borehole, making them an attractive option under modern industrial safety frameworks.

Strategic Benefits of Bulk Emulsions

The operational advantages of bulk emulsions have driven widespread adoption across major regional mining projects:

• High Volumetric Energy Density: Bulk emulsions fill the entire diameter of the borehole, maximizing energy coupling with the surrounding rock face for cleaner fragmentation.

• Enhanced Safety During Transport: Because the base emulsion matrix remains classified as a non-explosive oxidizer until sensitized at the mine face, transport risk across public highways is minimized.

• Resistance to Dynamic Desensitization: In complex blasting patterns, the shockwave from an early hole can collapse the pore spaces in adjacent holes. Modern bulk emulsions are engineered to withstand these dynamic forces, avoiding misfires.
