abstract = "Surface deformation and slope stability are important issues in
mining, for legal obligations, security, production planning, etc.
A recent survey of the main active mines in the country point out
a great number of open pit mines. Currently monitoring
deformations of this type of enterprise has been carried out by
classical surveying methods and geotechnical monitoring, which
provide highly accurate information, but have disadvantages
regarding the restricted area coverage, high cost of
instrumentation and operation, etc. In this sense, the increasing
use of orbitals SAR sensors (Synthetic Aperture Radar) provided a
big boost in the detection and monitoring of surface deformation
using the technique of advanced differential SAR interferometry
(A-DInSAR ). This technique is based on phase information of
specific targets present in radar images, called persistent
scatterers (PS - Persistent scatterers), obtained during the time
series of systematic SAR imaging surveys in a given period of time
(at least 15 scenes). The phase variation of these point targets
is related to the shifts in line of sight (LOS) direction during
the period of acquisitions, which may be of millimeter order. This
technique was applied to the monitoring of surface deformation of
the iron mines N4E, N4W, N5E, N5N and N5W located in Caraj{\'a}s
(Par{\'a}), and from the results obtained, a new application
research using more advanced techniques A-DinSAR will be held in
two iron ore mines in the Quadril{\'a}tero Ferr{\'{\i}}fero
region(Serra Curral / Serra da Moeda, MG). In this new research,
two orbital radars will be used (TerraSAR-X and COSMO-SkyMed) in
ascending and descending orbits, respectively, in order to obtain
information deformations in the line of satellite sight, as well
as in vertical and horizontal components of the surface
deformations, by untested approach in the country yet. The
A-DInSAR techniques to be used in this project will be the
SqueeSAR, from TRE company (Italy), the pioneer in this area of
knowledge, the IPTA (Interferometric Point Target Analysis) using
the Gamma software and SBAS (Small Baseline Subset) using the
software SARscape. The traditional DInSAR technique (differential
Interferometry SAR) will also be explored to complement the
extraction of information with orbital SAR data.",
