MODERN METHODS OF GROUND-BASED INTERFEROMETRY IN MONITORING ADJACENT ROCK MASSES IN OPEN PIT MINING
This article analyzes modern monitoring methods using ground-based interferometric radars. Currently, there are only a few companies on the world market that offer interferometric scanning solutions. These are IDS (Italy), part of the Hexagon group, Groundprobe (Australia), Reutech (South Africa) and the very rare LISA (JRC-Lisalab) and GPRI (Gamma Remote Sensing). Such radars can be used in the open pit mine development of mineral resources for monitoring the safety of adjacent rock masses, dumps and dams. The article considers the general principle of interferometric radars’ operation and differences between them. It also describes different types of aerials, which are being used nowadays in ground-based interferometric scanning. The analysis results enabled to formulate the recommendations for using different type radars depending on the strategy of geotechnical monitoring.
