Sandvik to unveil new battery-powered bolter, simulator and app at MINExpo

Sandvik Mining and Rock Solutions is set to unveil three new underground drilling solutions at MINExpo 2021 in Las Vegas, based around a common theme of electrification, sustainability and digitalisation.

The new products to be unveiled at the show, taking place from September 13-15, include a new battery-powered bolting rig, an accompanying portable training simulator and a new mobile application for enhanced drilling.

The new Sandvik DS412iE (pictured) is a highly automated, productive, battery-electric powered rock bolter for underground mining and tunnelling applications. It is equipped with an electric driveline system and battery package with electric motor for zero emissions while tramming and drilling, thereby reducing thermal load and underground ventilation requirements, Sandvik says.

The rig’s iSeries platform offers various levels of automation for rock support drilling as well as providing component commonality through the 400i drill range. The introduction of Sandvik DS412iE rounds out Sandvik’s first range of battery-electric vehicles for all underground drilling applications, according to the company.

Sandvik Digital Driller™ training simulators provide a compact and flexible solution to safely train underground drill rig operators or maintenance teams, the company says. The latest Digital Driller module is specifically designed to support the new Sandvik DS412iE battery-electric rig, with the new version retaining the key features of being low weight and highly portable, enabling it to be used where it is most needed – on site.

Use of the simulator is estimated to increase annual productivity by 5% due to increased rig availability alone, Sandvik claims. In addition, training costs are reduced by up to 35% through less energy and consumables costs and reduced rig damage.

The new Sandvik DrillConnect mobile application transfers drilling plans – including those created in iSURE® – drilling reports and MySandvik machine data in environments where network coverage is inadequate or not available. Sandvik DrillConnect removes paper-based processes and automates the data transfer between the office and drill rig via a customer’s preferred mobile device. The app also provides easy access to the machine’s troubleshooting and manuals and is designed to be scalable for future development, according to Sandvik. The first version will be compatible with iOS devices, with plans to introduce Android compatibility in future iterations.

Patrick Murphy, President of Underground Drilling at Sandvik Mining and Rock Solutions, said: “Our latest developments are based on the feedback we have received from customers. We have listened to their challenges and are developing solutions that ensure we will continue to lead the industry shift toward a more digitalised and electrified future.”

In addition to the new underground drilling solutions being introduced at MINExpo, a Sandvik DL432i tele-remote operator chair will be on display. Sandvik will also showcase the latest updates to its underground drilling product offering.

PYBAR sets records at Glencore’s Black Rock mine with Sandvik DL432i longhole drill

The introduction of PYBAR’s new Sandvik DL432i longhole drill in October 2020 has led to month-on-month improvements in drilling productivity at the Black Rock copper-lead-zinc mine, in Queensland, Australia.

Versatile and compact, the Sandvik DL432i is a fully mechanised electro-hydraulic top hammer longhole drill, designed for large-scale mining. The Sandvik iSOLO drilling control system allows the client (Glencore in this case) to provide electronic drill plans on a USB, which is plugged straight into the drill. The operator then lines the drill up on the survey markings and selects the required drill design, with the remainder of the drilling taken care of by the iSOLO software.

Since arriving on site, a specialised pump has been installed on the DL432i, allowing AMC (a subsidiary of IMDEX) to add a Bore Hole Stabiliser™ to the water circuit while drilling to improve hole integrity in the soft ground conditions. This technology, combined with Sandvik’s iSOLO drilling control software, has been key to PYBAR’s production success at Black Rock to date, the contractor said.

“The ground conditions at Black Rock have put Sandvik’s iSOLO drilling control system to the test, and the technology has proven itself with flying colours,” PYBAR said. “After several months of on-site refinement of the automated drilling system, the drill can now operate with minimal operator input.”

This has led to month-on-month increases in production drilling rates with a record month in March, closely matched in April, according to PYBAR. This, in turn, has meant a significant increase in available production fronts resulting in increased tonnes and improved overall project performance.

Trials of automated drilling for complete firing patterns will begin shortly at Black Rock to enable drilling to take place during firing and shift change, as well as free up the operator to assist with other tasks around the mine, PYBAR said.

The transition to further automation has the potential to significantly maximise both productive drilling time and overall performance for the project, it added.

Sandvik TH545i haul trucks, DL432i autonomous drill to join Barrick Hemlo fleet

Barrick’s Hemlo gold mine in Ontario, Canada, is lining up the arrival of a new Sandvik autonomous drill and eight Sandvik haul trucks as its underground-only contract miner strategy takes hold.

The company said it is expecting eight new Sandvik TH545i 45 t haul trucks to arrive on site in the near term.

These trucks moves more rock and material than its current fleet and are equipped with an ejector box, which means operators do not need to lift the box to dump material – it pushes it out the back – making it easier to work with in smaller areas, the company said.

“Let’s not forget to mention the reduction in emissions from this Tier 4 engine, improving worker safety and lessening the environmental impact,” the company added.

Earlier this week, a Sandvik DL432i fully autonomous drill arrived at Hemlo too. Its fully integrated software allows this machine to drill holes on its own, even between shift changes, according to Barrick.

“Engineers are now able to upload plans and designs for day-to-day operations,” the company said, adding that the cab is enclosed and comes with climate control to cool operators in warmer climates underground.

Late last year, Barrick said it would phase out the open-pit operation at Hemlo and move to an underground contract mining model as it looked to upgrade the mine to a Barrick Tier 2 asset. This saw Barminco appointed as the contract miner earlier this year.
