Interferometric Mine Slope and Landslide Radar Solution
The use of slope monitoring radar is now the standard practice for the active monitoring of slope in open pit mines and for safety critical landslide monitoring with the aim of providing alerts in the event of progressive movements which could potentially lead to slope failure and assessing worker safety. With the safety of workers at risk and equipment threatened, safely long-term monitoring slopes around-the-clock is a necessity. With early detection, accidents can be prevented. With long-term analysis, mine and civil engineering design can be optimized.
The IBIS radar is capable of collecting quantitative information on slope behaviour from either a spatial or a temporal point of view. It provides reliable early-detection alerts on impending failures in near real time, as well as, accurate geo-referenced outputs over long periods of time allowing users to integrate radar data into geotechnical analysis of slope failure mechanisms.
The unique IBIS-FM radar system accurately monitors multiple scales of displacements in real time, from early detection of slow movements to fast accelerations associated with slope collapse. The great operative range, up to 4500 m, allows to safely deploying the system in comfortably accessible areas, without exposing people and equipment to hazardous zones. Thanks to the most advanced automatic algorithms in the market, IBIS-FM delivers reliable and accurate data in all weather conditions. Monitoring experts can respond to slope hazards faster ensuring the safety of operators and the public. With this detailed information, appropriate action can be taken early enough and minimise the effects caused by possible slope failures and landslides.
IBIS-FM offers monitoring specialists:
- Continuously measurement of wall/slope movements with sub-millimetre accuracy from distances of up to 4 km,
- Reliable early alerts for progressive wall/slope movements to help avoid potential slope failure;
- Mapping the long term evolution of slow moving slopes.
- Adaptable and durable IBIS-FM delivers monitoring data even in the most extreme mining conditions
The IBIS –FM is a valid support for the advanced geotechnical modelling required for the assessment of slope stability with the following cutting-edge features:
- Highest spatial resolution: 0.5 m x 4.4 m resolution cell @1 km, resulting in the detection of smaller failure areas.
- Longest operating range: From 10 m and up to 4500 m.
- Extremely broad coverage: Can cover an area of approximately 5 km2 @ 2 km.
- Short acquisition time: Only a few minutes for a full resolution scan at long range (2 minutes @2 km).
- Long term monitoring: Either through permanent installations away from blasting restricted areas or by precise repositioning of the system.
- Completely automated operation: using solar panels and batteries, with diesel generator as back-up.
- High in-service availability: limited moving parts and low maintenance help keep down-time to a minimum.
- Fully remote operation: via wireless radio link.
- State-of-the-art atmospheric correction: the first and most advanced automatic algorythms in the market to provide always reliable results.
- Fully tested in harsh mining environments.
- Real-time results: designed for minimal data bandwidth consumption and fast processing engine for real-time data availability
Powerful and user-friendly, the IBIS Guardian software manages slope stability risks in both geo-hazard assessment and open pit mining operations. IBIS Guardian enables fast interpretation and therefore fast reaction time to vital real-time information delivered by the IBIS-FM radar system.
Reliable data with flexible alerts in real-time
Highly accurate displacement data is provided to monitoring specialists in real-time using the most advanced Automatic Atmospheric Correction algorithm.
IBIS Guardian offers alert messaging options and comprehensive geotechnical analysis tools. Monitoring specialists are immediately alerted in the event of slope displacement by means of various instant messaging options such as email, SMS or pop-up alerts.
Advanced data integration for even clearer understanding of slope stability
Automatically import different total station and GNSS datasets, for example from Leica GeoMoS©, to enable even clearer understanding of slope stability. Monitoring experts can com-pare prism and GNSS displacement trends, by mean of time series or Stereonet charts, with IBIS radar data to understand movement behavior that much faster.
Full Pit Monitoring 360 & True Vector
IBIS Guardian offers Full Pit Monitoring (FPM) capabilities, stitching together data sets from multiple IBIS radar systems onto a single radar map. The True Vector technology automatically resolve the spatial direction of displacement for hundreds of thousands of overlapping radar pixels monitored simoultaneously by two or more radars.
