Augered and pumped loading methods

Blended with ammonium nitrate porous prills to enable augered and pumped loading for improved efficiency in explosives delivery.

Reduced drill and blast costs through the application of greater energy

4D™ technology delivers an increase in energy in the blasthole, enabling blast patterns to be expanded, while maintaining the same explosive energy per bank cubic metre (BCM), reducing costs and expanding drill capacity.

Measure-while-drill optimised fragmentation

Ensuring only the required amount of energy is applied to each blasthole, delivering consistent fragmentation for the lowest possible cost.

Improved productivity

Fragmentation can be maximised, driving excavation productivity and downstream processing benefits including increased throughput, or reduced energy consumption.

Improved wall control

The ability to load lower energies without changing product types enables designers to apply reduced energy in buffer blasts, reducing vibration and damage as part of an overall wall management programme.

Click on the technologies above to learn how they contribute to the delivery of 4D™ bulk emulsion.

1. Bulk emulsion chemistry: New emulsion chemistry enables faster chemical sensitisation and significantly lower densities to be achieved and maintained.  
2. LOADPlus™: The smart process control system manages the delivery system process flows, ensuring the required blends and densities are manufactured and loaded efficiently. It can be operated in standalone mode, or connected mode to Blast IQ™.
3. Explosives delivery systems: An upgraded fleet of Bulkmaster™ and Pumpmaster™ Mobile Manufacturing Units (MMU™) with upgraded 4D™ gassing chemical system, injection points and new end of hose technology will support the delivery of 4D™ Bulk products.
4. SHOTPlus™: An upgraded blast design software that incorporates the 4D™ range of products based on relative bulk strengths, to enable blast designs based on the required energy, irrespective of hole condition. Blast designs developed in SHOTPlus™ can be wirelessly transferred via BlastIQ™ to the LOADPlus™ smart control system in the MMU™ to streamline the loading of blastholes according to blast design, thus eliminating the need for manual input.
5. BlastIQ™: MMU™s equipped with BlastIQ™ enable digital blast designs that are created in SHOTPlus™ to be wirelessly transferred to the MMU™. As-loaded blast data can also be transferred to BlastIQ™ with the continuous logging of MMU™ process drives for product quality control and assurance.

Low energy, wet blasthole application

Load lower energy Fortis™ 4D™ products than possible today into wet holes, better matching the energy to the geology and reducing cost through reduced mass of explosives loaded and improved MMU™ productivity, loading more blastholes per delivery.

Design based on Rock Strength, regardless of hole condition

4D™ technology allows the drill and blast engineer to design blasts based on the geology and the energy required, irrespective of hole conditions, enabling the lowest cost explosives to be loaded while maximising blast outcomes.

Fume risk reduction

Load lower energy products into wet holes, better matched to rock strength, while maintaining effective water resistance, reduces the risk of fume caused by over blasting in soft geology.

Improved productivity while delivering vibration outcomes

4D™ products with lower energy and density enables optimised blast design options based on the Maximum Instantaneous Charge (MIC), improving energy distribution and productivity by reducing air decking, increasing column length for the same MIC and enabling greater bench heights for improved drilling, blasting and digging productivity.
