IDS GeoRadar enhances algorithms for Guardian slope monitoring software

IoT, Mining safety, Mining services, Mining software, Water management, , , , , ,

IDS GeoRadar, part of Hexagon, has announced the new SMV algorithm for Guardian, its software for slope monitoring.

Developed by IDS GeoRadar’s R&D team together with major players of the mining and monitoring industry, SMV is the result of a two-year collaboration and development, it says.

“Guardian SMV provides a revolutionary approach to radar monitoring as the first algorithm specifically designed for low vegetated assets’ management,” IDS said. “Guardian SMV processes radar data for the early detection and visualisation of very slow deformations in low vegetated environments – typical of tailing dams. The implementation of an innovative velocity estimator extends the sensitivity to impressive low-end velocity ranges, similar to satellite InSAR.”

IDS says Guardian SMV provides a unique reduced noise level with an optimal filtering of the noise caused by low vegetation and drastically reduces the decorrelation effects on radar data.

Guardian SMV performs an efficient and continuous monitoring of low vegetated environments supporting professionals in the early detection of ground instabilities, it added. This sees the solution provide “unprecedent benefits” for continuous monitoring of very slow movements, reducing the negative effects of low vegetation on radar data and providing a reliable detection of displacements in the few mm per month velocity ranges.

IDS GeoRadar widens rockfall radar support with latest RockSpot update

IDS GeoRadar, part of Hexagon, has announced a new software update for RockSpot, its innovative radar system able to locate, track and notify on rockfalls.

RockSpot’s latest software release expands the data analysis performance with new tools supporting an efficient rockfall risk zonation, TARP fine tuning and back analysis to reduce operational and geotechnical risks, according to the company. The new multiple statistical tools allow users to manipulate the events database and plot custom charts based on defined areas and items – such as event rate, duration/area extension, velocity and run out distance of rockfall – for a comprehensive back analysis, models calibration, integrity of rockfall controls and design change justification.

Rockfalls are a major safety threat in open-pit operations. The sudden onset of rockfall events makes it difficult for conventional monitoring methods to provide adequate pre-warning and a comprehensive analysis, resulting in a challenge for mine operators and planners.

RockSpot is, according to IDS, the industry’s first end-to-end solution able to trigger notifications on rockfalls in real time and to maximise rockfall hazard management, providing an explorable rockfall database for back analysis and an automatic classification of falling events.

This compact and powerful radar picks up falling rocks in near to real time and working crews receive prompt notification for action along with immediate access to all event’s details that are tracked, stored and classified in a rockfall events database.

IDS concluded: “RockSpot provides 24/7 continuous monitoring night and day to actively support in sync risk management with real-time notifications and improves risk mitigation and planning operations with multiple statistical tools to analyse the collected data for cost reductions in mitigation measures.”

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, a member of the Orica Group, has launched BlastVision®, a world-first solution that, it says, delivers actionable blast performance insights for optimal safety and productivity.

The crucial data aids in the detection of potential misfires and out-of-sequence firing and in identifying and tracking fly rock, according to the company. Intra-blast monitoring also adds valuable wall control insights, such as monitoring and mapping instantaneous blast damage to slopes and identifying movement on significant structures.

GroundProbe, a specialist in geotechnical monitoring, leveraged the partnership with Orica, a leading mining and blasting solutions provider, to gain information around current blast monitoring methods through interviews with engineers, according to GroundProbe CEO, David Noon.

“Through talking to mine site engineers responsible for blasting on the ground, we identified that many sites were still using quite simple and sometimes unsafe methods for blast analysis.

“Techniques included recording blasts with ground-based camera systems and conducting visual inspections of this footage to determine areas of concern.

“From this, the idea of using drone footage and automated algorithms to quickly identify key areas of interest was born.”

BlastVision takes custom high-speed drone footage of a blast as it happens, using world-first advanced proprietary algorithms and modern AI frameworks to convert the footage into analytics data, according to GroundProbe. Data is then remotely analysed in its custom software platform, with insights swiftly reported back to the site. From these insights, mine site personnel can optimise blasting and monitor the impacts of blasting, improving both safety and productivity, the company said.

The solution has been tested, trialled or demonstrated across over 60 mine sites around the globe, positively impacting hundreds of drill and blast team members across these mine sites, according to GroundProbe.

GroundProbe’s VP – Technology, Fernanda Carrea, said that no other solution provides the range of insights from the whole blast area that BlastVision provides, from start to finish.

“BlastVision provides an increased level of safety, efficiency, accuracy and productivity through our software algorithm automatically identifying key areas and issues,” Carrea said.

“Data is also able to be captured before, during and after a blast, and covers the blast area in its entirety.

“We can proudly say that this patent-pending technology is a world first.”

IDS GeoRadar, part of Hexagon, has announced a new solution for geotechnical professionals that, it says, pioneers the introduction of artificial intelligence in slope stability monitoring – Ai.DA, the AI-based software monitoring tool for Guardian.

Ai.DA is an artificial intelligence-based software tool providing an additional smart processing layer to radar data. Ai.DA, through the use of algorithms, simplifies the identification of movements from possible residual noise by evaluating the consistency of the detected movement trend with typical slope instabilities behaviours and models, helping professionals to optimise processes and take better decisions, IDS says.

Ai.DA is an intelligent support to radar data interpretation and is fully integrated with Guardian, IDS GeoRadar’s software to manage slope stability risks in both open-pit mining operations and natural geo-hazards. Guardian’s processed radar data is automatically pushed to Ai.DA providing an additional smart processing layer that highlights quick moving areas through an intuitive interface with a clear and detailed view on a 3D map.

Ai.DA can provide simultaneous data processing of radar data originating from one to six different radars and
highlights timely localised and quick moving areas, which are often difficult to manage, for improved decision making, the company says.

“With Ai.DA, we are pioneering the use of artificial intelligence in slope stability monitoring, and we commit to providing customers with state-of-the-art technology solutions to support radar data interpretation,” Angela Patera, Guardian Product Owner at IDS GeoRadar, said. “Interpreting the big amount of available data is the new challenge for geotechnical engineers and Ai.DA represents a valuable support to this demanding task.”

Geoscience software company Seequent has announced the release of GeoStudio Core, a new, completely reformulated SIGMA/W product.

These upgrades allow geotechnical engineers to understand and tackle major engineering challenges for infrastructure and mining projects – from dams and levees to tunnelling and the stability of cuts in underground and open-pit mines, the company says.

Paul Grunau, President of Seequent’s GEOSLOPE, says GeoStudio Core 2021 is the most significant GeoStudio release in the past five years.

“SIGMA/W has been completely redeveloped from the ground up, delivering new levels of confidence and capability for geotechnical engineers needing to assess ground deformations and stability,” Grunau said. “The new strength reduction stability analysis in SIGMA/W complements the industry-trusted solutions in SLOPE/W to provide a rigorous understanding of slope failure mechanisms, allowing the engineer to design effective stabilisation measures. These products integrate with SEEP/W to include the impact of changing groundwater conditions, providing a comprehensive solution for stability problems.

“The combined GeoStudio Core solution runs in a single integrated environment, speeding up the project workflow and easily scaling with the user’s needs. All project data and analyses can be combined into a single project file, enabling smooth data exchange and simpler data management.”

GeoStudio Core, with SIGMA/W’s expanded material model library and new analysis types, allows for comprehensive modelling of a wider range of soil and rock behaviour, according to Seequent. For example, simulating the strain-softening behaviour of brittle clays enables stability control of a tailings dam or roadway cut.

The new GeoStudio multi-physics solver enables SIGMA/W to offer improved solver performance and enhanced modelling of rapid reservoir drawdown, open-pit mine dewatering effects on highwall stability, and solute transport from tailings ponds.
