A like-for-like Sandvik Bolting Head (SBH) upgrade at the New Afton mine, in British Columbia, Canada, is delivering a significant productivity boost at the New Gold-owned operation, according to Sandvik Mining and Rock Solutions.

Launched over a decade ago, New Afton’s now ageing Sandvik DS300 drill rigs are being given a new lease of life, thanks to an upgrade that sees a current generation bolting head fitted in a like-for-like replacement. Not only is maintenance more straightforward and spare parts easier to source, the new bolting head is delivering a remarkable productivity increase – of 25% – Sandvik claims. In fact, so successful has the mine’s 2021 upgrade been that New Gold has recently confirmed a second of its Sandvik DS300 drill rigs will be given the treatment.

Bolting rigs are used to stabilise hanging and side walls in underground mine applications.

“The upgraded SBH bolting head fitted to the Sandvik DS300s is the business end of the drill and features the latest RD300 series rock drill,” Francois Nell, Sandvik Mining and Rock Solutions’ Head of Rebuilds and Upgrades, says. “This makes it perfect for rock reinforcement in underground mines with small-and-medium cross sections. Different bolt type and length configurations are available, providing an extensive bolt selection, while a full bolt carousel ensures the DS300 is capable of installing up to 15 bolts, ranging from 1.6-3 m in length. Bolt types include cement grouted, resin grouted, anchor point and friction bolts.”

There are several benefits of adding new technology to ageing drills, according to Nell.

“The new SBH is already proven in the field and gives an instant performance boost, thanks to the RD314’s much improved penetration rates,” he explained. “Added to that is the convenience of being able to source readily available current parts more easily, as well as increasing mine’s parts commonality across more drills.

“Also, the new SBH doesn’t put the rest of the D300 under additional strain; in fact, due to the lighter RD314 drifter compared to the drill it replaces, machine strain is, if anything, reduced.”

The SBH upgrade itself is straightforward, coming in kit form, and can be conducted by a mine’s in-house technical teams using the instruction manual the SBH comes with, according to Sandvik. Taking at most a couple of shifts to complete, customer feedback regarding the installation process has been universally positive, the OEM says.

With several hundreds of Sandvik’s Lyon, France-built D300s still working around the world, Sandvik says it expects that this SBH upgrade will be as popular with other mines as it is at New Afton.

Sandvik Mining and Rock Technology plans to launch its first and one of the the mining industry’s first battery-powered rock bolters next year, as it continues to roll out new solutions to electrify the underground mining space.

The Sandvik DS412iE extends the zero emissions concept to the underground rock bolter class and opens a wide range of possibilities for mines driven to boost their productivity and safety with data-based analytics, according to the company.

In its core mission of delivering productive, secure and versatile rock support solutions, Sandvik rock bolters have a clear track record, according to the company.

“Still, these tools’ automation and data acquisition capabilities have not been as advanced as their production and development drill rig counterparts,” the company said. “Scheduled for launch during 2021, the new Sandvik DS412iE rock bolter will complement the intelligent family of next-generation battery-powered underground drill rigs.”

Anssi Kouhia, Product Manager, Rock Support Drills, said the DS412iE is basically an upgrade on its existing Sandvik DS411.

“We have received positive feedback about that model,” Kouhia said. “We made an accomplished model even better with more advanced automation capabilities, improved data acquisition and upgraded ergonomics.”

Like the battery-powered DD422iE  jumbo drill, the rig trams on battery and carries out drilling and bolting when connected to the mains power.

Along with its direct predecessor, the new intelligent bolter also has much in common with the larger Sandvik DS512i in the 5 x 5 m drift size. One example is their similar versatility in terms of bolting systems: Sandvik DS512i and Sandvik DS412iE can handle a wide range of bolt types and lengths, including a combination of automatic cement mixer and automatic resin injection on the same bolter.

The new Sandvik DS412iE will effectively complete Sandvik Mining and Rock Technology’s rock support drill range for the 4 x 4 m class, updating its entire product range to the latest i-standard of connectivity and automation capabilities, the company said. Additionally, the Sandvik DS412iE will be the supplier’s first battery-powered rock bolter.

“In other words, the zero underground emissions approach will now include all stages of the underground mining process: rock support drilling as well as development and production drilling and loading and hauling,” Sandvik said. “The ability to virtually eliminate underground particulate matter, NOx, CO2 and heat emissions is first and foremost a major health and safety benefit, but also offers cost savings by reducing mine ventilation power requirements.”

The new rig responds to major industry trends that customers have identified in feedback sessions, Sandvik said.

In addition to reducing underground emissions and improving working conditions, the safety and environmental improvements also make economic sense by reducing time lost to injuries and costs. The advanced automation capabilities will increase the speed and safety of the bolting cycles as well as open a range of possibilities for process optimisation, the OEM said. “This will translate into more reliable rock supporting and safer working environments.”

Like one-hole automation that has been a standard feature in Sandvik mining and tunnelling jumbos, the one-bolt automation feature of Sandvik DS412iE now extends this capability to rock bolters, Sandvik said.

“The rig can carry out a single bolting cycle unassisted, so that in optimal conditions the operator only needs to manually relocate the boom from one bolt location to another,” the company said.

The battery-powered unit will come with two automation levels: the standard Silver package from the outset and, in the near future, the optional extended Gold level. The main difference between the two packages is in the remote monitoring and operating capabilities and in the measurement-while-drilling functionality.

The automation packages seamlessly mesh with Sandvik iSure software, according to the company. Available as a standard tool for designing drift drilling plans and blasting plans, iSure now increasingly extends to bolting operations and comes in three levels: iSure Basic and iSure Plus for the standard Silver automation package, and iSure Premium for the optional Gold level automation. The advanced automation solutions can offer a significant productivity and quality boost, Sandvik said.

“With iSure, you can design a bolting pattern in the office, transfer it to the rig over Wi-Fi or on a USB flash drive, carry out the bolting according to the pattern, and, on top of that, you can retrieve a report that compares the plan and the realised bolting pattern,” Kouhia says.

iSure compatibility, in particular, enables more extensive data acquisition and reporting, Sandvik said.

In addition to the bolting pattern, the retrieved data will also include various parameters that characterise the quality of the bolting process, such as grouting concrete consumption and bolt tightening torques. This can serve to document the bolting process in much greater detail than it did previously, which enables more accurate quality control of the rock supporting measures.

The verifiable track record of the rock support measures taken provides systematic safety documentation and, should a failure still occur, the bolting process reports can help to determine the cause of it, down to the level of an individual bolt – when it was installed, how it was installed and whether it complied with set specifications.

Full compatibility with the My Sandvik fleet management portal and the OptiMine suite of digital mine automation and analytics solutions further enhances the connectivity of Sandvik DS412iE, providing all-round data-based control for rock support operations, the company said.

While the main areas of focus for Sandvik DS412iE surround automation, connectivity and data acquisition capabilities, productivity has not been neglected, Sandvik said.

The new boom control system, advanced boom manipulator mode and optimised bolting head movements help the operator to achieve a smooth and efficient process by keeping the bolting head automatically aligned with the correct bolt fan positions and angles, the company explained.

In terms of sheer mechanical power, much of the new bolter’s high productivity derives from the new control system of the Sandvik RD314 rock drill, which substantially increases the output and penetration rate. Overall, the productivity upgrade is roughly 25% from previous models, according to Sandvik.

The Sandvik DS412iE includes many safety and ergonomic features.

The bolter is designed to be compliant with the EN16228 standard for drilling and foundation equipment, which is harmonised with the requirements of the European Machinery Directive. One of the EN16228 requirements is an access detection system (ADS). In the Sandvik DS412iE, the ADS automatically scans the surroundings of the bolter and alerts the operator should a person enter the work area, which effectively reduces potential accidents. The safety improvements also include a fully covered steel strand reel.

The Sandvik DS412iE continues the bolter class’ legacy of secure and effective cabin design, Sandvik says, with a 55% percent improvement in visibility, better effective vibration control and significant noise reduction adding up to a safer and more comfortable workplace for the operator.

Future launches will also include a diesel-powered version, Sandvik DS412i, which will be compliant with the latest engine emission specifications, Sanvik said.

MacLean Engineering says its newly developed virtual reality (VR) bolter technology will be front and centre on its booth at this year’s CIM Convention, in Montreal, from April 28-May 1.

The VR tool on show will provide visitors with a hands-on experience of the immersive training world of virtual ground support installation, the company said.

Two other MacLean technology initiatives will also be highlighted in convention presentations – battery-electric vehicle (BEV) material haulage trial results; and, real-time vehicle monitoring that delivers a shortlist of actionable data to support operator safety, machine life and predictive maintenance practices.

MacLean’s Vehicle Monitoring System (VMS) technology package will be discussed during an Innovation Stage presentation on the trade show floor on Monday afternoon, while MacLean’s BEV material haulage ramp trial results from 2018 will be the focus of a technical session on the Wednesday afternoon of the convention.

“This past year we made significant investments in our in-house technology development capabilities,” said MacLean President, Kevin MacLean.  “This means we now have our own teams of vehicle monitoring programmers and remote-control mechatronics experts – a whole new generation of MacLean employee, one that will help propel the company’s product development along the path from remote to semi-autonomous to fully-autonomous fleet operations.”

“Our 2018 purchase of an underground test facility in Sudbury gives these new teams a world-class underground mining lab for technology prototyping and product testing, all at the service of delivering safer, more productive, less costly fleet operations to our global customer base,” added MacLean Founder and Chairman, Don MacLean.

“Maclean’s technology push is closely linked to the imperative of training to ensure safe and sustainable adoption of new technology in the underground environment,” said Patrick Marshall, Director of Mining Technology. “As mining companies go deeper and to more remote locations to chase economic orebodies, they are necessarily going to be operating in jurisdictions without longstanding, experienced mining labour forces. So, the focus needs to be on training and that means providing the whole range of tools and expert trainers, required to build knowledge to be passed along at site level on an ongoing basis. Our VR Bolter is one of those tools – a highly transportable, accessible and engaging learning environment developed expressly for the next generation of miner who has grown up in a digital age, just as mining itself is joining the digital age in a significant way.”
