SLOPE STABILITY MONITORING
The Maccaferri Steelgrid ® HR System combines a patented high strength steel wire mesh geocomposite which is used in conjunction with anchor plates
developed to work also in remote areas , where
cell coverage is not available . Unlike traditional systems , HELLOMAC signals events on every single portion of the barrier , allowing the detecting system to be restored in a simpler and more economical way .
IDS GeoRadar ’ s RockSpot
With a 30 years hands-on experience , IDS GeoRadar , part of Hexagon , provides geotechnical professionals and major mining companies with a comprehensive portfolio of mine monitoring solutions : from highperformance radar systems , to powerful software applications , from customised support packages to professional Monitoring Services .
While IBIS-ArcSAR is one of the world ' s most established and trusted slope monitoring radars , IDS GeoRadar says its RockSpot has consolidated its position as the most advanced rockfall tracking radar able to detect and track localised events and not just to address large-scale failures .
RockSpot is an innovative radar system able to locate , track and notify on rockfalls and mudflows in real time , solving long-time issues in open-pit mines by providing the right technology for an overall improved quality performance in risk mitigation and a reduction in risk management & planning costs .
Designed to withstand all weather conditions , providing night and day continuous monitoring , this radar is able to pick up rock falling events and notify users of rockfalls for their action . RockSpot also consents the creation of a database with all the recordings of falling events and statistics occurred , allowing a better planning of risk mitigation measures .
As a leading provider of intelligent monitoring solutions , IDS GeoRadar also recently pioneered the introduction of Artificial Intelligence across the monitoring radar applications with Ai . DA , an AI based software tool supporting radar data interpretation .
Developed by industry geotechnical experts in over three years of training on true monitoring data sets , Ai . DA provides an intelligent processing of radar data for human review , serving as a monitoring supporting tool for the early identification of localised and fast slope instabilities .
Ai . DA is a tool fully integrated with Guardian , IDS GeoRadar ' s powerful and user-friendly software to manage slope stability risks in both open pit mining operations and natural geohazards . Guardian ' s processed radar data is automatically pushed to Ai . DA that offers an additional smart processing layer highlighting quick moving areas with a clear and detailed view on a 3D map and an intuitive user interface . Ai . DA can provide simultaneous data processing of radar data originating from one to six different radars and highlights timely localized and quick moving areas , which are often difficult to manage , for an improved confidence in decisionmaking .
With the shortage of geotechnical engineers on the current market , interpreting all the data coming in is now a key challenge for companies and having an external backup for this activity has a role to play . IDS GeoRadar provides Assisted Monitoring services with 24 / 7 remote data monitoring through a growing worldwide network of highly qualified staff , dedicated to supporting in real-time its mining customers . The 24 / 7 control room staff notify the customer on significant changes in deformation trends and triggered alarms , such as equipment stops , based on a Standard Operating Procedure defined together with the Customer and provide prompt communication for the activation of shared response protocols to threats .

Maptek – from highwall survey to mine design conformance
Maptek laser-based monitoring solutions allow operations to safely survey pit highwalls and dam walls remotely standoff . Stability analysis can be conducted on high resolution Maptek laser scans and accompanying digital imagery . Laser scanning and modelling tools provide a safe and reliable solution for mapping tailings dams to manage risk . Repeated mapping allows close management of the integrity of tailings dams and shows regulatory bodies that safety issues are being considered .
The Sentry laser-based wall monitoring system allows operations to track surface movements and analyse deformation trends . Maptek laser scan data is combined with sophisticated Sentry software to track and analyse movement over time . Wall monitoring data enables operations to gain a better understanding of how materials behave during mining and sites can apply Maptek laser scanners to all survey , monitoring
