SLOPE STABILITY Five GroundProbe Slope Stability Radars will soon be in full operation to detect any future movement and instability of the Samarco Santarém and Germano tailings dams. Two of these are safety-critical, mobile radar systems (SSR-XT) such as shown here allowing enough time for personnel to remove themselves from site before a failure occurs. GroundProbe has also been providing daily geotechnical reports, training and continued local support. As a follow up to this, in May 2017, GroundProbe announced that was to be the sole provider of radar monitoring solutions at Samarco Mineração S.A. Five Slope Stability Radars will be in full operation to detect any future movement and instability of the Santarém and Germano dams, with GroundProbe supplying two safety-critical, mobile radar systems (SSR- XT) and three long-range, fixed-deployment radar systems (SSR-SARx). “The complete, tailor-made monitoring solution of Real Aperture Radar (RAR) and Synthetic Aperture Radar (SAR) technologies ensures the right mix of technology is being employed for the specific needs of the application. GroundProbe is the only company in the world that offers all slope stability radar technologies, linked by a common software solution, so is well-equipped to meet the needs of any site-specific application.” John Beevers, MD and Chief Executive Officer, GroundProbe, spoke of how GroundProbe was able to secure the key, exclusive partnership following a competitive evaluation process. “There have been two radar vendors operating on-site for the last 18 months, allowing the Samarco geotechnical engineering team to directly compare and evaluate RAR and SAR technologies,” Beevers said. “Coupled with the support services offered from our industry- leading Geotechnical Support Services team, software engineers and product reliability teams, we were able to answer questions and fix issues fast, providing constant support to the Samarco geotechnical team.” The radars form an integral part of Samarco’s complete risk reduction strategy; an industry- leading solution specifically developed for tailings dams, to assess further risks and hazards. Samuel Ricardo Carvalho Carneiro, Geologist, Samarco, said the purchase of five radars cements their commitment to safety and best practice in terms of monitoring. “We have invested heavily in the continued monitoring of the project, employing a wide range of monitoring solutions to ensure the stability of the dams. We have selected GroundProbe as the sole supplier of all radars, based on both their suite of AUGUST 2017 | International Mining 69
