Epiroc brings autonomous drilling to small underground mining segment with the Boomer S10 S

Epiroc has released what it says is the world’s first automated one-boom jumbo for the small segment in the form of its new Boomer S10 S.

This rig pushes the boundaries of what to expect from a face drilling rig, according to the company, providing near surgical precision in drilling and major cost savings throughout the cycle – all thanks to being the world’s first one-boom jumbo featuring Epiroc’s Rig Control System.

The consistent, repeatable and quality-assured results are made possible by advanced automation, operator-assisting features and digital drill plans, Epiroc says.

“With Boomer S10 S as our latest addition, we are proud to offer a sustainable automated operation for the small segment, with a complete range of automated rigs for face drilling, production drilling and rock reinforcement underground,” Sarah Hoffman, VP Sales & Marketing at Epiroc’s Underground division, said.

The new Boomer S10 S comes with quality drilling and cost savings in terms of wear and tear of rock drilling tools, spare parts and other consumables, according to Epiroc. Compared with traditional, non-automated one-boom jumbos, the rig decreases the consumption of consumable parts by 30%, while lowering maintenance costs by 12%.

Thanks to the digital drill plans and Epiroc’s Rig Control System, the drill rig is perfectly aligned in the drift to optimise accuracy, providing less overbreak and underbreak, and longer pull rounds, Epiroc says.

Epiroc’s Rig Control System is used for controlling several vital functions in Epiroc’s machines. It is also an enabler for several productivity-increasing, efficiency-boosting and cost-saving automation features, according to the company.

Niklas Berggren, Global Product Manager, Face Drilling Equipment at Epiroc, said: “The Rig Control System provides drilling accuracy way beyond what human eye measure could ever accomplish. It is high-quality production from start to finish, and a great milestone reached for mine development.”

When applying the High Performance Development method – a way of working during the entire drill cycle – the Boomer S10 S offers up to 25% more development metres compared with traditional one-boom jumbos, according to Epiroc. The total cycle time is reduced thanks to better pull-length, fragmentation and reduced scaling needs.

“It’s a snowball effect on productivity: accurate drilling holes means less explosives, less scaling and better tunnel profiles,” Berggren says. “In turn, a better tunnel profile means less rock reinforcement and less tear on all the machines in the drift. All this leads to significant cost reductions while increasing productivity and safety for everyone involved.”

The machine is designed for great ergonomics with lower vibration and sound levels (<75 dbA), and also offers improved visibility and a multi-functional joystick.

Epiroc commits to ‘next generation’ of underground mining with new Boomer M20

Epiroc has taken what Niklas Berggren, Global Product Manager for Face Drilling Equipment, says is the next logical development step in underground face drilling design by creating a new Boomer with protected hydraulics, sensors and cables.

The Epiroc Boomer M20 is designed and built to minimise unplanned stops and maximise uptime and performance in highly demanding operations by removing what is thought to be the biggest downtime drain in underground face drilling – the need to stop production for hose changes.

Epiroc explains: “A challenging part of underground work is the everyday wear and tear on hydraulic hoses. Falling rocks and debris, and the continuous wear against the tunnel floor and walls, means constant hose repairs.”

The Boomer M20’s heavy duty hose-less boom design minimises unplanned stops for hose repairs, keeping the rig up and running even in the toughest conditions, the company said.

Developed in close collaboration with key customers, the Boomer M20 is the result of extensive research and real-world testing, according to Berggren.

“This is the perfect choice for mining houses and contractors that want to out-drill the competition through innovation,” he said.

High drilling precision and performance are ensured thanks to on-board automation features, tele-remote capabilities and digital drill plans, which give higher reliability and quality of the full drill cycle, Epiroc claims.

By utilising high performance mine development options, such as Epiroc’s ABC Regular for longer rounds, higher accuracy, reduced overbreak and better quality tunnels, the Boomer M20 allows the operator to adjust and download drill plans directly at the face, eliminating the need for adjustments on the surface, Epiroc says.

“With digital drill plan handling, drill rounds will be longer, more precise and give far less overbreak,” Berggren said. “We have seen total cost savings of up to 25% and up to a 40% productivity increase.”

He added: “This is a very well-functioning option; on the Boomer M20, we have reinforced the technology on the face drilling rig itself so that we can utilise this option better in a harsh mining environment.”

The Boomer M20 is designed with safety at its core.

Through tele-remote capabilities, operators can drill from a safe distance away from hazardous areas at the tunnel face, while also keeping production going over shift changes. Multi-functional joysticks mean operators can always keep their eyes on the task. The cabin, reinforced with noise and vibration dampening materials to keep noise levels as low as 65 db, meanwhile, is designed for optimum visibility.

The safe bolting platform is another great safety feature that avoids operation under unsupported rock.

Such options set the Boomer M20 up to “take the lead for face drilling automation features into the future”, Berggren said.

Epiroc is continuing its charge towards electrification in underground mining with the new Boomer M20, providing a battery-electric driveline option to allow the machine to tram to the drill location on battery power and carry out drilling while plugged into the mine’s electrical infrastructure.

“A battery-powered Boomer M20 brings additional savings on health, maintenance, ventilation and cooling,” Epiroc said.

Berggren added: “With the on-board charger, the operator does not need to plan for charging as it automatically takes place while connected to the grid for drilling. Thanks to the high-capacity battery, the Boomer M20 has a fantastic driving range, and there is nothing to disturb the drift cycle.”

Epiroc President and CEO, Helena Hedblom, who stars in a campaign video for the Boomer M20 that sees the face drill balancing on its booms on a mountain top, said: “The Boomer M20 is another great example of how we make a difference through innovation.”

The Boomer M20 is available for commercial sales in the September quarter of 2021, and will shortly head to a customer site in Australia for tests, followed by trials at customer sites in Spain and Sweden.

Epiroc says it plans to rollout the new internal hydraulics design across the future Boomer range.
