GroundProbe cancels out atmospheric ‘noise’ with new slope stability monitoring algorithm

A collaboration with mining operations across the globe has resulted in the development of a new atmospheric correction algorithm for Slope Stability Radar (SSR) that, GroundProbe says, provides a step change in the way atmospherics are treated and managed.

Precision Atmospherics is the most advanced correction algorithm in the market today, according to the company, able to distinguish and significantly reduce the noise caused by the most turbulent atmospheric conditions, providing a decisively clearer picture of real deformation.

It is the result of several years of rigorous development, testing and evolution, and represents one of the most significant research and development projects GroundProbe has ever undertaken, the company says. GroundProbe partnered with a global collection of mines in different climatic regions in the extensive validation program, including one of the largest open-pit mines in the world, Rio Tinto Kennecott’s Bingham Canyon copper mine in Utah, the US.

Rio Tinto Kennecott’s Senior Engineer, Geotech, Dustin Hicks, has been part of Precision Atmospherics development and testing since 2019, when first presented to Kennecott’s Bingham Canyon mine.

“GroundProbe delivered an SSR-Omni equipped with Precision Atmospherics to Bingham Canyon to demonstrate its capability in the rapidly changing atmospheric environment that our site experiences,” Hicks said.

“The Precision Atmospherics algorithm effectively managed a variety of atmospheric conditions including blast and wind induced dust plumes, rain and snow, which resulted in significantly less contaminated data.

“It reduced the noise on a scan-by-scan basis, which opens the door for tighter alarm configurations that would otherwise overburden the geotechnical team.”

In complex atmospheres, especially at large mines, atmospheric variability can hinder the ability to detect early-stage movement.

Precision Atmospherics is currently available on GroundProbe’s 2D Real Aperture Radars fleet. The combination of real aperture technologies with this algorithm allows mine sites to have better deformation detection capability in all seasons and conditions, according to the company.

GroundProbe’s Chief Executive Officer, David Noon, said Precision Atmospherics is a game changer in tracking both slow and rapid trends.

“With the smoother plots and cleaner maps that Precision Atmospherics provides, customers can focus their attention on recently started or slow-moving deformation,” he said. “This is important for gleaning the potentially significant geotechnical problems that can only be detected through long-term analysis.

“Both rapid and slow trends are shown in a single data set, and unlike other techniques, there is no post-processing required to detect slow movements.”

Alberto Cabrejo, GroundProbe’s Global Practice Lead – Geotechnical Advisory, added: “Precision Atmospherics is the most important addition to the monitoring practice using interferometric radars. It responds directly to the most important request from Geotechnical Engineers around the world: data quality.

“With this algorithm, we can finally use tight alarms appropriate for rock mass deformation rather than alarms that will not be triggered by weather changes.”

GroundProbe reflects on geohazard monitoring developments on 20th anniversary

GroundProbe says it is immensely proud to be celebrating 20 years of operation and 20 years of keeping people and communities safe.

Over the last two decades, the company has expanded from a home-grown start-up to become a global innovation powerhouse and the trusted partner of companies around the world, it said.

GroundProbe calls itself a global leader in real-time geohazard monitoring technologies that help manage risk, ensure safety and increase productivity across mining and civil projects. Evolving from a PhD project at the University of Queensland, Australia, in 1993, by 2001, GroundProbe’s founders commercialised the world’s first patented Slope Stability Radar (SSR), which is now widely used to monitor mine walls and warn before collapses occur.

GroundProbe CEO and founder, David Noon, said that the success of GroundProbe’s business and its continual year-on-year growth is built on a culture of innovation and customer intimacy that permeates through every level of the company.

“GroundProbe has now deployed more than 700 systems and support services to customers in more than 35 countries,” he said. “To get to that level, we have proudly built long-term, trusted relationships with the top 20 mining and resources companies, globally.

“Across all of those deployed radars and customers, and in our entire 20-year history, I am most proud to say that we have fulfilled our ultimate goal by making mining safer. Our technology has never failed to detect a collapse, ultimately saving numerous lives.”

Anglo American’s Head of Geotechnical – T&S Group Mining, Lesley Munsamy, recently stated that the company is honoured to have played a part in GroundProbe’s history. The miner celebrated a number of “firsts” with GroundProbe, with the capturing of the first ever slope deformation data, the detection of the first ever slope failure and the first international radar deployment at Anglo American mine sites, GroundProbe said.

“Our mutually-beneficial partnership is based on GroundProbe’s impeccable safety track record and continuous innovation of its hardware and software tools,” Munsamy said. “The precise and valuable data that GroundProbe provides our sites has had an impact on our safety and productivity by enhancing our risk-management practices.

“GroundProbe redefined the slope risk management practices across the world. The availability of reliable real-time monitoring has had a significant impact on safety, a contribution that cannot be underestimated.”
