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.

Byrnecut, OZ Minerals and Sandvik achieve teleremote drilling first

Contract miner Byrnecut Australia has become the first underground operator in the world to successfully use a new automation and teleremote package for Sandvik development drills.

Byrnecut introduced a Sandvik DD422i development drill featuring the package to OZ Minerals’ Prominent Hill gold-copper mine, southeast of Coober Pedy, South Australia, in March.

With COVID-19 travel restrictions preventing Sandvik staff from attending site, Byrnecut, OZ Minerals and Sandvik experts collaborated via phone, teleconference and email to complete remote commissioning of the rig.

The two-boom rig, which can be monitored and controlled from the surface and features a sophisticated boom-collision-avoidance system, has now been in operation for three weeks, according to the companies.

Byrnecut Australia Managing Director, Pat Boniwell, says the new automation features allow for enhanced drill operation across shift changes – a period when, historically, development drilling has stopped or been significantly reduced.

“We’re conservatively looking at a 10% increase in productivity with this machine through being able to drill extra holes and the machine being used more consistently,” he said. “It picks up on the deadtime, and if it does stop for any reason we’re able to remotely reset it.”

The new boom collision avoidance system means both of the rig’s drill booms can be left in operation during shift change – something that was previously not possible. In the first few weeks of operation, the drill has been able to drill 60-70 holes while being operated autonomously and remotely from surface, the companies said.

General Manager of OZ Minerals Prominent Hill operations, Gabrielle Iwanow, says when Byrnecut approached her about trialling the upgraded development drill, she was immediately interested.

“OZ Minerals is a modern mining company,” she said. “We’re interested in innovation and looking for safer, faster, and more efficient ways of doing our work.”

Iwanow said the commissioning of the drill in such trying times is a true credit to all those involved and the positive working relationship between OZ Minerals, Byrnecut and Sandvik.

Byrnecut Drill Master, Noah Wilkinson, says a solid working relationship with Sandvik and good communication contributed to the success of the commissioning.

“People from the Sandvik factory in Finland were able to remote into the machine over the internet and adjust settings that were stopping some of the functions from working,” he explained.

Sandvik’s Global Account Manager for Byrnecut, Andrew Atkinson, paid credit to Byrnecut’s openness to adopting autonomous technologies in areas including development drilling, loader operation, production drilling and ore trucks, which are all engineered for compatibility with Sandvik’s AutoMine® and OptiMine® products.

In addition to the collision avoidance and teleremote capabilities of the DD422i, the new automation package allows for semi-autonomous bit changing.

Another handy feature of the setup during the current period of social distancing has been the virtual network computing capability that allows the control panel of the drill to be viewed remotely on a tablet. This means that during operator training, the instructor need not be in the cabin with the operator.
