Increase Accuracy. Reduce Over-break. Increase Advance

The development drilling process is heavily reliant on operator skill/training. This reliance, combined with the inherent complexities of underground mining often results in inaccurate and inconsistent drilling, which in turn produces poor development blasting outcomes.

Typically these outcomes are unplanned overbreak and dishing of the face, which increases haulage cost and reduces rate of advance. The net is slower and more expensive development drilling, reducing NPV for asset owners and decreasing margins for contractors.

Minnovare’s Development Optimiser™ system combines advanced hardware with a digital platform to improve the drilling accuracy to ensure the drilling is as per the design.

KEY BENEFITS

The system allows operators of all levels of skill and experience to accurately bore in line with design, to deliver more consistent blasting outcomes for every cut. The result is more optimal blasts, reduced over-break and increased rate of advance. This delivers a lower cost/faster development drilling process. Highly accurate and applicable for use on ALL development drill rig makes and models.

Improve Drilling Accuracy

• The Development Optimiser system delivers superior setup accuracy – the primary cause of blast-hole deviation;
• System maintains rail trajectory to designed target and parallelity between rails;
• Works independently of onboard systems;

Achieve Optimum Blasts / Cuts

• Reduce over-break / underbreak and dishing of the face;
• Improve fragmentation;
• Reduce associated operating costs (scaling, grading haulage and processing);
• Increase the rate of advance;
• Increase drilling productivity with less time spent on rework and more time drilling.
