The Opti-Box (Blast Optimisation Box) is a self-contained, secure unit permanently mounted to the production drill rig which wirelessly connects with the Production Optimiser Mobile Interface inside the rig cabin.
Minnovare’s advanced technology auto-calculates the optimum ‘dip’ and ‘dump’ angle of the boom in real-time, independent of the rig’s on-board systems. Rig levelling and alignment to laser lines is no-longer essential – saving on rig setup time.
Inaccurate rig setup and collar misalignment are the primary causes of blast-hole deviation. Sufficient deviation leads to sub-optimal blasts, which in turn leads to over-break and under-break, inconsistent fragmentation (over-sized or under-sized rock), re-drills and ultimately excessive ore dilution (waste rock).
As part of the complete Production Optimiser system, the Opti-Box works independently of the rig’s on-board systems to significantly increase rig setup accuracy and accuracy at the collar – leading to a reduction in blast-hole deviation and therefore greater accuracy at the toe/breakthrough point. Using the Production Optimiser, early site implementations show that the number of holes drilled to within tolerance was doubled.
This vastly improved accuracy delivers optimum blasts – reducing the likelihood of over-break and under-break scenarios, which in turn significantly improves average dilution (with some sites as much 62%). Fragmentation size is also improved. With less time spent on rig setup and re-drills, more time is spent drilling – with some sites recording up to 20% more metres drilled per shift.

- Can be fitted to any production rig make and model. Secure, self-calibrating and rugged design, capable of withstanding the harsh underground mining environment, the Opti-Box requires virtually zero ongoing maintenance.
- Independent of the rig’s on-board alignment systems, setup error is minimised at the collar resulting in greater accuracy at the toe.
- Syncs wirelessly with the CORE Mobile App loaded onto the Production Optimiser Mobile Interface, mounted inside the rig cabin. Automatically captures all drill data to digital plans and plods (Digi-Plan / Digi-Plod) for future syncing with mine planning software.
