Mining Software is a Gamechanger at Oz Minerals

Oz Minerals implemented Epiroc's Mobilaris Mine Intelligence software and gained a better?understanding of where machines and people were physically?located underground – and operations became safer.

Since commencing production in December?2019, the Carrapateena copper gold mine has become over the past?decade one of the biggest mining?projects in South Australia. The ore?must be hauled from the production?levels to the crusher level via a short?decline with limited passing areas,?which poses challenges. In order to?optimize haulage flows, mine operator?OZ Minerals deployed Epiroc’s?Mobilaris Mining Intelligence decision?support system to digitize?the mine.

"We saw potential to remove some of the constraints we have underground. You can’t see around corners, and you can’t see through rock, so understanding where things are – where people and machines are – is a lot more difficult than in a typical workplace on the surface."

Real-time data and superior 3D visualization make it possible for everyone everywhere to know what is going on underground.

OZ Minerals rolled out the first feature in 2019:?Mobilaris Situational Awareness, a solution for?surface control room operators. Mobilaris Onboard,?a solution for underground operators in?vehicles, followed in 2021. Thanks to real-time?3D visualization, anybody with access to a tablet?or a PC can quickly understand where machines?are operating.

?“Mobilaris Situational Awareness allows you to see, live, at any point in time, where all the equipment and people are in the mine. It also allows you to navigate to locations, equipment and refuge chambers,” said Bruce.

OZ Minerals had initially installed Wi-Fi tags?on all its vehicles, which provided accuracy to?around 150 meters. With Mobilaris Onboard, it?can achieve accuracy to 5–10 meters without any?extra infrastructure, and all that is needed are?basic OBD2 adapters or a Doppler radar. Implementation?started with trucks and loaders,?and now the entire underground fleet has been?equipped. This has significantly improved realtime?position information.

The Carrapateena copper-gold mine in South Australia faced logistical challenges that were solved thanks to Epiroc’s Mobilaris Mining Intelligence decision support system.

"Everyone at the site operations center – dispatchers, mine controllers and haulage control – is now using Mobilaris Situational Awareness. Previously, it could take quite a bit of time to search for a piece of equipment, but it only takes seconds now to see its last location."

The system also helps OZ Minerals with its fleet?management – to determine where trucks are,?for instance – thus becoming a tool in the decision-making process.?“For those who are perhaps new to the mine,?we’ve been able to insert points of interest on the?map, for example where it is best to hold. Cycle?times are well managed, despite underground operations?becoming a lot busier,” said Schmidt.?

?OZ Minerals then implemented a second Mobilaris?feature: Mobilaris Onboard, a tablet in a?vehicle that acts just like a car navigator but without?any need for a dedicated tracking infrastructure.?This provided everyone underground with a?tool that enabled them to easily understand how?equipment was positioned around them. “This is another piece of information that the?operator can use to make a decision – and all of?these minute decisions add up to a more productive?and safer workplace,” said Bruce.

"One of the main benefits is that we’re able to travel down and get to our locations a lot better."

For truck captain Joel Dodd, everyday work has?become easier thanks to Mobilaris Onboard.?“One of the main benefits is that we’re able to?travel down and get to our locations a lot better.”

?OZ Minerals now has around 200 tablets in?vehicles underground – not just in trucks, loaders?and face drill rigs, but also in light vehicles – and?the feedback has been very positive.?“When people can see more clearly where other?people are, it helps them avoid unwanted interaction,”?said Bruce.

OZ Minerals

OZ Minerals is a mining company based in Adelaide, South Australia. The company was formed by the merger of two Australian non-ferrous metals mining businesses – Oxiana and Zinifex. OZ Minerals operates three mines: Carrapateena (Australia), Prominent Hill (Australia), and Carajás East (Brazil).

Carrapateena mine

Copper concentrate (containing gold and silver) mine, located 160 kilometers north of the regional center of Port Augusta, in South Australia. The Carrapateena exploration project was acquired by OZ Minerals in 2011. Construction was complete and the first saleable concentrate was produced in 2019. Carrapateena ranks as one of the biggest mining projects in South Australia in the last decade.
