Operational decarbonisation has become a key focus of large-scale Australian iron ore producers in recent years. As producers continue to target long-term net zero goals, there has been an increase on focus for suppliers to provide solutions that align with these goals and maintain operating effectiveness. Slope stability radar monitoring requires reliable electrical power to charge batteries on the radar that are utilised in the operation of the radar. In many countries, this has been mains power that is particularly common in mines that use electric shovels. In the iron ore mines of the Pilbara onboard power generation has been required. This has been historically in the form of diesel generators, or bespoke solutions tailored to individual systems to provide green energy. In using diesel gensets, high maintenance requirements often require frequent travel of personnel to remote locations to maintain and repair onboard power solutions, further increasing environmental footprints to maintain real-time operational slope monitoring. However, in the development of ad hoc green solutions, solar systems have been utilised on an as-needed basis and can encounter development difficulties when applied to mass production. Furthermore, solar solutions are often seen as an ancillary power source rather than a single solution. To achieve the long-term operational needs of producers to meet net zero goals in open pit applications, slope monitoring systems need to see a reduction in their environmental footprint. For this to be achieved, systems need to be manufactured on a scale that is repeatable, reliable, and capable of meeting or exceeding current performance levels. In the case of slope monitoring radars, it is not uncommon for system downtime to have a direct correlation to production, or economical loss due to radar monitoring forming a key piece of the mining risk-management framework. Furthermore, in some instances monitoring outages can have a direct impact to the safety of mine personnel, if the radar system is not available to alert on slope movement. IDS GeoRadar, in collaboration with key customers in Western Australia, developed a solar-only solution for its IBIS ArcSAR radar systems that that are now produced alongside diesel powered systems at the assembly level. To date, 11 ‘Green ArcSAR’s’ have been deployed to iron ore operations in the Pilbara region of Western Australia, utilising the exceptional solar potential of the Pilbara region. This paper discusses the results of long-term deployment performance, availability and benefits related to lower carbon footprint radar monitoring. As many existing customers already have a need to deploy slope monitoring radar to manage risk associated with pit wall fall-of-ground events, the difference in cost between a diesel-powered solution and a fully solar solution represents an overall cost increase of approximately A$25 000 for additional battery capacity and management systems. In comparison, labour and fuel costs to ensure ongoing diesel generator operation can cost in the order of A$6600 per annum. Over a seven-year service life, this represents a minimum saving of approximately A$52 000 without considering additional overheads typically associated with diesel systems and reduction in net CO2 emissions.
