Expanded Ammonium Nitrate Explosive

Rock-type expanded AN explosive is a lightweight, porous, and loose explosive created by combining self-sensitized expanded ammonium nitrate, which is produced using composite surfactants and specialized crystallization control techniques, with high-energy liquid fuels and porous fibrous solid fuels. This process is based on the "hotspot" theory of detonation, surfactant theory, and ammonium nitrate self-sensitization principles.

This explosive is suitable for blasting operations in mine shafts and surface sites without gas, methane, or mine dust hazards. It is widely used in surface mines, quarries, underground mines, tunnels, and railway and highway construction.

Key Benefits

The explosive offers excellent explosive performance with low bulk density, good charge coupling, and strong work capacity, making it suitable for various soft to medium rock blasting operations. It is particularly effective in soft rocks containing soil and other materials.

The explosive is resistant to moisture absorption and caking during its storage period, ensuring safety and stability.

The explosive has good free-flowing property, suitable for loading into blastholes of various diameters.
