GroundProbe commits to tailings dam monitoring
GroundProbe’s new high precision, fast scanning and long range doppler radar is paving the way in emergency geohazard monitoring to help improve tailings dam safety
IMPROVING GLOBAL TAILINGS DAM monitoring practices continues to be a key pillar of GroundProbe’s vision of maximum safety for the mining industry. In more recent times especially, a large number of mine sites have begun actively adopting best-practice monitoring solutions for tailings dams as a necessity. Globally, sites are accepting of the fact that it is just as important to the overall safety of the mine that they monitor non- operational areas as well as areas of high production. GroundProbe has deployed custom monitoring solutions to tailings dams across Brazil, Peru, Canada, Mexico, Australia, and multiple African countries. Each tailings dam is unique and so is the consequence of failure should the dam collapse. In most instances, several sensors are deployed to effectively manage the potential risk posed by a
tailings dam collapse and often include both predictive and reactive technologies. If the solution incorporates multiple systems or sensors, it is integral that users have some way to bring all the data from the sensors together for analysis and identification of trends.
Reactive geohazard monitoring The RGR-Velox is a military-precision reactive monitoring
and alarming system for tailings dam breaches, large slope failures, landslides, and avalanches which can be disruptive, destructive, and at worst, fatal. It detects, tracks and alarms on moving geohazards in real-time, keeping people, assets, and communities safe by giving warning of a breach or collapse. The RGR-Velox is the latest technology to be born
from GroundProbe’s R&D and product development programmes, and the most recent innovation to be added to the company’s already extensive fleet of technologies and services. For a comprehensive approach to risk-based

monitoring and ultimate safety, the RGR-Velox can be combined with GroundProbe’s predictive monitoring technologies and support network, systems, and services. Its predictive monitoring solutions (slope stability radars and lasers) detect and warn people and communities of impending mine collapses, dam failures, rockfalls and landslides. Conversely, the RGR-Velox, a reactive monitoring solution, tracks, and alarms on already moving geohazards post-collapse, giving early warning to take action or evacuate through alarm outputs such as lights, sirens, pagers, or phones. Together, they deliver a complete, state-of- the-art monitoring strategy to better manage risk and ensure maximum safety. The RGR-Velox sweep-scans an entire area instantly, much like taking a radar photograph, to capture actionable information as it happens and provide new details of the scene every 0.25 seconds. Perhaps most impressive is the device’s ability to

differentiate and locate small moving objects with precise accuracy. Leading with the smallest minimum object size, lowest minimum detectable speed, and finest range resolution and angular precision, the RGR-Velox can detect a 0.3m x 0.3m object from 1km – moving at just 0.05m per second – and can correctly locate the object in space to a precision of 0.2° x 1.7m. Its alarming capabilities are completely
customisable, ensuring users are empowered to design alarms tailored entirely to their specific site challenges and conditions.
