Rio Tinto Autonomous Mining Operations — Pilbara, Western Australia

Content

Rio Tinto operates one of the world's largest fleets of autonomous mining equipment across its Pilbara iron ore operations in Western Australia. The company deploys 40 autonomous drills on 5 drill platforms across 7 mine sites, with all drilling activity planned and supervised remotely from the Perth Operations Centre — a single controller can manage up to 8 different drills across multiple sites per shift from a single console. This removes operators from hazardous site environments, reducing safety risks associated with heavy machinery. The autonomous drill fleet delivers safety benefits by eliminating operator exposure to high-risk areas, while also improving drilling accuracy for mine planning, productivity, and environmental outcomes through more precise blast-hole placement. Smart charge trucks automate the pumping of explosives into drill holes, using computer systems and data analytics to determine the correct amount of explosives for each hole, reducing wastage and improving blast effectiveness. Rio Tinto's Mine Automation System (MAS) operates like a network server, pulling together data from 98% of sites and processing it using sophisticated AI algorithms. The system provides information in a common visual format through RTVis, Rio Tinto's 3D visualisation platform built on gaming engine technology. AI capabilities include automatic generation of orebody models, automated equipment dispatch, predictive blast control, and optimisation of autonomous truck speed with reduced queuing — all producing significant productivity gains. The company also operates Operations Centres in Perth and Brisbane enabling integrated remote management of mines, processing facilities, ports, and rail systems using real-time data visualisation, predictive analytics, and AI. Drones with thermal diagnostic capability perform equipment inspections and slope safety monitoring, identifying issues like elevated friction rates in real time so maintenance teams can respond immediately.
