 GLOBAL NEWS Volvo is finding innovative ways to reduce costs in an underground mine. Chile’s growing mining industry remains at the top of the copper production league table. It now represents 10% of the country’s total GDP and there are more than 30 large operational mines in Chile. Volvo Construction Equipment machines are present in almost half. With greater efficiency in mind, one of the biggest mining companies in the world, Codelco, is looking at projects such as Volvo CE’s 5G underground mining test pilot – to set the example of finding innovative ways to reduce costs and increase capacity. “Automation and electromobility are important enablers to make mining safer, cleaner and more productive According to Rafael Nieweglowski, Volvo’s director of the Southern District in Latin America, automation and electromobility are important enablers to make mining safer, cleaner and more productive. “But mining companies are increasingly looking at connectivity as having the biggest potential impact on the way they work,” says Nieweglowski. In underground mining, machines often work as deep as one kilometre underground. Having a strong mobile connection is vital to keep machines ‘talking’ to one another at subterranean levels. A robust wireless connection will also allow for remote monitoring to 16  African Mining  January 2020 predict when maintenance is required, oversee the productivity of the entire operation, maintain optimum machine uptime and, most importantly, cut costs. In practice, remote monitoring with real-time data means it is possible to see, for example, if a machine might be consuming more fuel than the others despite performing exactly the same tasks in exactly the same conditions. If the cause is that an operator is not using the machine in the correct way, then the system knows this and instructs managers to carry out appropriate training. This then leads to reduced fuel consumption, reduced costs and early prevention of a problem that could have escalated over time. Rafael cites another key benefit for connectivity in mining. “If a machine breaks down inside the mine, it stops the operation not only because that machine can’t work, but also because the routes in and out of the mine are so tight that other machines cannot pass. “At Volvo, we have an advanced telematics system called CareTrack to predict machine failures like this, but the main challenge now is how to keep 100% connectivity all the time.
