- Improved safety for both personnel and equipment;
- Reduced production delays due to increased knowledge of the rock mass strength and early warning of slope instability;
- Fast alarm response and low false alarm rate due to high spatial resolution and fast scan time;
- Reduced service disruptions due to a highly robust construction and a limited number of moving parts;
As open-pit mines get deeper, massive slope failure can occur with little or no warning. In view of this situation, IDS has developed a unique radar system – IBIS-FM – capable of:
Continuously measuring mine wall/slope movements with sub-millimetre accuracy from distances up to 4 Km;
Providing reliable early warning alerts for progressive wall/slope movements than can potentially lead to failure;
Mapping the long term evolution of slow moving slopes.
IDS has furnished IBIS-FM with a suite of advanced technologies which overcome the deficiencies of the previous generation of slope radar systems. IBIS-FM now offers the following leading edge features:
- Highest spatial resolution: 0.5m x 4.4m resolution cell @1 km, resulting in the detection of smaller failure areas.
- Longest operating range: From 10 m up to 4000 m.
- Extremely broad coverage of pit walls: Can cover an area of around 5 km2 @ 2 km.
- Low acquisition time: Just a few minutes for a full resolution scan at long range (2.5 minutes @2 km).
- Long term monitoring: Through either permanent installations away from blasting restricted areas or by precise re-positioning of the system.
- Fully self-powered operation: Using a combination of solar panels and batteries, only switching to a diesel generator as a back-up.
- High in-service availability: A limited number of moving parts and low maintenance requirements help to keep down-time to a minimum.
- Fully remote operation: Provided by a wire-less radio link.
- Advanced atmospheric estimation.;
- Fully tested in harsh mining environments.
IBIS Guardian makes use of state-of the art automatic atmospheric correction algorithms to provide accurate and reliable displacement maps which are fully geo-referenced on a digital terrain model.
The capability to handle long-term projects with large datasets makes Guardian also suitable for the long-term tracking of movements which is potentially useful for regulators, the back analysis of slope failure and more comprehensive geotechnical/geological analysis.
