Geospatial Insight launches service to monitor tailing dam ground movements

Global Mining Review,

Geospatial Insight has announced the launch of the new MotionMonitor-TFS service, in collaboration with Terra Motion Limited and the University of Nottingham. The service has been specifically designed to monitor ground movements in and around mine tailing dams and provide early warning of potential structural failure.

Combining the unique APSIS© algorithm, developed by Terra Motion Limited with risk modelling methodologies devised by the University of Nottingham, MotionMonitor-TFS will provide tailing storage facility (TSF) managers and environmental, social and governance (ESG) compliance officers with a comprehensive and reliable solution to monitor multiple tailing dams in one platform, offering timely identification of developing risk factors in and around the tailing dam structure without the need for ground sensor or infrastructure installation and providing an early warning of potential dam collapse.

Identifying potential failure, at an early stage, will enable companies to implement damage limitation strategies and, where appropriate, action to prevent failure can be launched minimising the financial and environmental fallout.

A recent study conducted by the University of Nottingham and Durham University revealed that the 2019 Brumadinho dam collapse in Brazil could have been foreseen using the APSIS algorithm. Lead author of the study, Dr Stephen Grebby, concluded that using this technique “the failure date could have been predicted to within a week of it happening. Crucially, this prediction would have been possible around 40 days prior to the collapse, allowing time for a warning to be raised that the dam was becoming unstable.”

The collaboration between these organisations combines pioneering innovative tech with data analytics and visual intelligence to deliver an early warning service which has the potential to revolutionise the mining industry.

“Terra Motion are proud to be working with Geospatial Insight to bring this product to market. We see it as a perfect match between the unique capabilities of our APSIS processing techniques and their ability to develop it into a commercial actionable risk warning service,” said Andy Sowter, CTO of Terra Motion.

“MotionMonitor-TSF is a ground-breaking approach to monitoring and highlighting ground surface movement around and within mine tailings facilities, helping to identify potential catastrophes before they happen and thereby preserving life, livelihoods, reputation and property,” added Dave Fox, CEO of Geospatial Insight.
