Brazilian iron ore miner Vale will begin the testing phase for the implementation of two autonomous off-road trucks at the Carajás mine in November. The innovation comes together with actions of development and training of mine professionals to follow the world trend of the Fourth Industrial Revolution, also called industry 4.0.The implementation of the autonomous operation has been taking place in conjunction with people development actions, which includes the creation of a training center in the city of Parauapebas by the supplier.The definitive start-up of production is expected to occur at the end of the first half of 2020. All professionals who will interact with the autonomous equipment will be trained. The Carajás mine will operate part autonomously, but will also continue with conventional operation. The results will be evaluated for the expansion of the fleet.It is estimated that by 2024 37 autonomous trucks will be operating in Carajás, which represents about 40% of the current fleet.In autonomous operation, trucks are controlled by computer systems, GPS, radars and artificial intelligence and monitored by operators in control room miles away from operations, which brings even more safety to the activity. When detecting risks, the equipment stops its operations until the path is cleared. The security system's sensors are capable of detecting larger objects such as large rocks and other trucks, as well as human beings in the vicinity of the road.
