abstract = "The Caraj{\'a}s mineral province encompasses the world's largest
iron reserves with excavation carried out through open pit
benching. Mining operations in the area have significant areas of
rock mass movements and surface displacements that potentially
lead to slope instabilities with risks to personnel, equipment and
production. Instabilities can be expected due to deep excavations
in rock masses of low geomechanical quality, blasting practices
and heavy precipitation. In this paper, ground instabilities are
monitored through an integrated SAR analysis based on a data-stack
of 33 TerraSAR-X images. This approach was designed to monitor
distinct displacement regimes, ranging from small to high
deformation rates, and to map surface changes, based on variations
of radar reflectivity. Results were compared with field
information (total station/prisms, ground based radar, geological
and geomechanical maps), and the approach showed to be effective
for monitoring ground deformation in the region. Due to its
capabilities (synoptic view, high accuracy, dense grid sampling),
the complementary use of space-based SAR with field monitoring
systems proved to be strategic for operational mining planning and
risk assessment in this challenging environment.",
