Abstract: BHP Western Australian Iron Ore (WAIO) operations use a suite of slope monitoring systems which are deployed to operational areas based on the ground control risk. Slope radars are one part of this system. During 2022, WAIO completed the deployment and integration of a network of 22 radar systems across its operations. This digital solution enables data transfer between physical radar systems located in open pits and to onsite offices, a vendor-supported remote control room in Indonesia and the WAIO Integrated Remote Operations Centre in Perth. Data analysis and monitoring of system and displacement alarms is now conducted around the clock: 24 hours per day, seven days per week.
Part one of this paper provides an overview of the technology solutions that were implemented to cater for increased capacity demands, remote access and service continuity.
Part two focuses on new processes including the partnerships established between BHP’s geotechnical, remote operations and technology teams, in conjunction with the Hexagon mine monitoring team, which have all been integral to ensuring a reliable, robust and scalable slope monitoring solution.
Part three focuses on business replication across BHP Nickel West (NiW) operations as well as other Hexagon customers worldwide.
