abstract = "Now spanning five simultaneous open-pit operations with
exploration carried out through open pit benching, Caraj{\'a}s
complex encompasses the world´s largest iron reserves. Open pit
mining operations in the area can lead to slope instabilities with
risks to personnel, equipment and production due to intense
excavations in rock products of low geomechanical quality,
blasting practices and heavy precipitation. Thus, an effective
prediction and management of surface deformations should be a key
concern for the mining operations. The ground displacement
monitoring techniques in Caraj{\'a}s include surface measurement
techniques at discrete points (total station/reflective prisms)
and over area using SSR (Slope Stability Radar, a ground based
radar). On the other hand, DInSAR techniques are receiving
relevance in the mining industry for reasons such a synoptic and
continuous coverage without the need for ground instrumentation
and a point-to-point good accuracy of measuring displacements
(millimeter to centimeter scale) over a dense grid. Using a stack
of 33 StripMap TerraSAR-X images acquired over Caraj{\'a}s
covering the time span from March 2012 to April 2013, a monitoring
approach is discussed based on the complementary use of
information provided by DInSAR (DInSAR Time-Series and Persistent
Scatterer Interferometry) and surface measuring techniques (total
station/prisms, ground-based radar).",
