Mine development

With high-precision drilling, operations are guided by digital drill plans that support the operator throughout the entire process. This ensures control over both the start and the end of each hole, delivering accurate burden and spacing with every round.

By standardizing execution across operators, high-precision drilling enables optimized charging based on local rock conditions. At the same time, feedback from the full drilling and blasting cycle can be captured and used to continuously refine and improve the drill plan.

The result is a more controlled and efficient process, achieving longer pull, improved fragmentation, better control of overbreak and underbreak, and reduced damage to the surrounding rock.

Optimizing charging based on the drill plan and local rock conditions ensures predictable and repeatable results in every round. With precise drilling, the use of explosives can be reduced - particularly in contour holes - while still achieving optimal breakage.

This results in longer pull, minimized rock damage, and well‑controlled overbreak, delivering high‑quality contours after blasting.

The outcome is a more stable profile, improved safety, and a more efficient process with better overall cost performance.

With High Performance Development, drill plans are executed with greater precision, increasing pull to 95–100% - all the way to the bit. This ensures that more rock is removed correctly in each round, improving overall cycle efficiency.

The benefits go beyond drilling accuracy. Standing rock that remains after blasting is often already fractured, leading to increased wear on rock drilling tools and higher consumption of spare parts. It also requires additional charging and blasting, adding cost and extending cycle times.

By achieving full and consistent pull from the start, High Performance Development reduces rework, lowers tool wear, and minimizes the need for additional explosives - delivering a more efficient, predictable, and cost‑effective drilling and blasting process.

Bolting efficiency depends heavily on the quality of the previous stages. When the surrounding rock is stable, with minimal fracturing, loose rock, or voids, bolt installation becomes both faster and easier.

With improved drilling precision and controlled blasting, the need for rock reinforcement can also be reduced, depending on the mine’s bolting strategy. This leads to a more streamlined support process with increased safety and productivity.

The combination of Boltec with Auto Bolt Reload, Self Drilling Anchors and pumpable resin allows several autonomous functionalities that previously were not possible for conventional rock bolting rigs.

Single bolt auto, multi bolt auto and teleremote control are features that can help to increase productivity, and reduce the requirement for an operator to be physically in the machine.
