Blasting Solutions
4D™ Bulk System
A revolutionary bulk explosives system that matches a wider range of explosives energy to changes in geology in real time.
A revolutionary bulk explosives system that matches a wider range of explosives energy to changes in geology in real time.
4D™ is an advanced bulk system that supports surface and underground blasting operations and can be tailored instantaneously to suit varying hole conditions for the desired blast outcomes. Enabled by Orica’s proprietary emulsion chemistry and smart technologies, operations using 4D™ can achieve accurate, automated and efficient energy control. Outcomes include improved orebody recovery, reduced overall explosive consumption and better fume, vibration and nitrate leaching control.

Features and benefits
Features and benefits
Adaptable energy control
Match energy to changing geology and bench conditions to achieve predictable, consistent blast performance across surface mines. 4D™ helps you adjust energy where it creates the biggest improvement in blast outcomes.
Augured and pumped loading
Blended with ammonium nitrate porous prills to support both augured and pumped loading, improving efficiency and consistency in explosives delivery
Improved productivity
Better energy placement drives consistent fragmentation and reduces the load on downstream activities like hauling crushing and processing.
Low energy, where control matters
Apply lower energy near final walls, boundaries or sensitive areas to maintain wall control and reduce vibration. Improve blast reliability while protecting geotechnical integrity and reducing the need for remediation.
High energy where strength is needed
Use higher energy only in harder or more demanding zones to break rock effectively. Improve fragmentation, reduce oversize and support faster, more consistent load and haul performance across surface operations.
Automation and repeatability
LoadPlus™ forms part of the 4D™ system, automating the charging process to deliver accurate and repeatable loading in every blasthole for more consistent blasting outcomes.
