Automation: quarries the perfect place to start

Why autonomous transport solutions will happen in quarries and small-scale mining operations first

CREATING solutions capable of maximizing transport efficiency through advanced automation is the goal of an entire industry. For Volvo Autonomous Solutions, it is likely to happen first in the controlled world of quarrying and mining.

After developing steadily, step by careful step, for more than 100 years, the automotive  world is currently in the grip of a two-sided revolution: on the one side under pressure to  reduce emissions by going electric, and on the other, striving to reach the Holy Grail of transport – the vehicle/machine that does not need an operator.

Whilst great strides have been taken in the switch to hybrid and all-electric drive, creating autonomous transport is proving harder to perfect.

‘Automation has struggled in the mainstream automotive world because they are trying to get autonomous vehicles to work everywhere and safely coexist with all the variables of life – cars, trucks, bikes, people, dogs, cats – you name it,’ said Perjohan Rosdahl, head of off-road at Volvo Autonomous Solutions.

‘Solving all these issues at the same time is proving to be an enormously complex challenge, even for the world’s biggest automotive and technology companies. Our approach is to start small, in a tightly confined environment and build on our successes over time. A perfect place to start is quarries, which have clearly defined load-and-dump locations over generally short circuits.’

The move to autonomous machines will not be simply a case of replacing a machine with an operator to one without. Autonomous machines will prompt the automation of the whole process and require a new way of looking at the entire operation.

Volvo Autonomous Solutions were created on 1 January 2020 to develop and commercialize autonomous transport solutions for the whole Volvo Group.

As well as providing adapted machines from within the Volvo Group, Volvo Autonomous Solutions will support customers with solutions to autonomous machines’ other challenges, namely the supporting infrastructure, control towers, repair and maintenance, virtual drivers etc, and even run the operations if needed.

‘It’s as much about a new mindset as it is about developing autonomous machines,’ said Uwe Müller, sales and marketing lead for off-road solutions at Volvo Autonomous Solutions. ‘We are talking about automating a transport process, not just selling a single machine. Because of that, we need to develop a total solution to manage this full process.’

Volvo Autonomous Solutions are working closely with the Volvo Group’s other business areas, especially Volvo Construction Equipment in the off-road segment. This ensures that new machines, whether developed specifically to be autonomous – such as Volvo’s award-winning TA-15 hauler – or traditional operator-based equipment, use the same autonomous drive platforms, coding languages etc.

This, in turn, allows them to be ‘talked to’ in the same way, as well as offering the ability to scale up easily. Not all machines will be autonomous, but being ‘autonomous enabled’ allows Volvo Autonomous Solutions to supercharge the standard products into operator-less machines, using their own proprietary autonomous drive kit.

‘To reduce the complexity of the world we need to standardize the process as much as possible,’ said Mr Müller. ‘We can do this in quarries as they are in a confined area, are highly regulated, and it’s easier to separate autonomous transport from other processes. Involving loading and dumping, the process itself is simple and repetitive.’

‘We are starting small with less-complex cases and will build on our successes,’ added Mr Rosdahl. ‘With the right customer partners, the next step could be underground mining and tunnel applications – autonomous machines (especially electric ones) work just as well in the dark as in the light, and it’s good to remove people as much as possible from these hazardous locations.

‘From there we could focus on large earthmoving projects that are still contained but have more variables to cope with, as our technology becomes more embedded over time. There are many R&D challenges to be overcome, but autonomous solutions are coming and they will be disruptive to current business models.’
