Orica’s 4D bulk explosives tech gains traction in Australia

Having launched its 4D™ bulk explosives technology at MINExpo 2021 in Las Vegas, in September, Orica is now demonstrating the innovation to coal customers on Australia’s East Coast.

The 4D bulk system enables the real-time tailoring of explosives energy to geology across a blast, delivering improvements in fragmentation, on-bench productivity and an overall reduction in drill and blast costs, according to Orica. It is designed to enable customers to, the company says, seamlessly match a greater range of explosives energy across a mine’s geology and target specific blast outcomes in real time.

Back in September, the company said the first release of 4D would begin with Australia from the end of 2021, and it appears Orica has stuck with that schedule.

“We are happy to share that, in Australia, we are currently demonstrating 4D to customers in the East Coast’s coal mines, each with a unique focus to their needs,” the company told IM. “For example, with one customer, we are demonstrating how 4D technology can reduce their overall drill and blast cost through lower explosives consumption, as well as better manage vibration in specific areas of their operation.”

With another customer, Orica is applying the 4D technology to its Fortis™ Clear range of bulk explosive products – formulated for use in applications where the generation of post-blast fume could be experienced – to demonstrate the reduction of fume risk in soft and wet ground, it added.

The technology is also being developed across Orica’s Fortan™ and Aquacharge™ bulk systems but will eventually be applied across Orica’s full suite of bulk systems.

4D is being delivered to these customers through Mobile Manufacturing Units (MMU™) equipped with LOADPlus™, Orica’s proprietary in-cab smart explosives delivery control system that, it says, enables accurate and efficient delivery of formulated explosives products to plan.

By combining emulsion blended with ammonium nitrate porous prills, 4D supports both pumped and augered loading methods across dry, wet and dewatered hole conditions. An outcome of this capability is greater on-bench productivity by Orica’s fleet of 4D-enabled, without the need to change raw materials in the MMU, Orica says.

Delivering up to 23% more relative bulk strength for hard-rock applications and up to 43% reduction in soft-rock applications, 4D will enable a broader range of applications, according to Orica.

Orica said in its half-year results to the end of March 31, 2022 that it was expecting to roll out the 4D technology to more sites in the second half of its financial year.
