IBIS-FM
Benefits

  • 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-FM is supplied along with the Guardian software suite which is specifically designed for critical and background monitoring. Guardian provides automatic real-time processing of radar data, visualization of displacement maps with multiple analysis options (extraction of time series for displacements, velocity, inverse of velocity) and the possibility to create multiple hazard-maps with user-defined alarm criteria for active monitoring.

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.
