                         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).",
