abstract = "Differential synthetic aperture radar interferometry (DInSAR) is a
space-geodetic technique which allows minute surface displacements
over vast areas to be detected with centimetric accuracy. Because
of these unique characteristics, the DInSAR approach has great
advantages over classical geodetic monitoring systems that allow
the anticipation of high-risk situations. In the past few decades,
it has been successfully applied in many areas of the earth and
environmental sciences. However, there have been very few
applications of this approach to active open pit mines in tropical
environments. In this work, the DInSAR technique was applied to
detect and monitor unknown surface displacements that may be
occurring in the N4W iron mine, northern Brazil. X-band data
acquired from March 2012 to April 2013 during the TerraSAR-X
satellite mission were utilized for this purpose. The results were
checked in the field and compared to optical leveling data. Due to
the consistent deformation pattern observed over a mine waste
pile, Pile W, we also performed numerical modeling in order to
carry out a preliminary assessment of its theoretical deformation
behavior. The results show that most of the study area can be
considered to be stable. The numerical modeling indicated that
horizontal displacements may be occurring, and that the DInSAR
technique can be used to provide an initial rapid assessment of a
large-scale deformation field, which could prove to be very
useful, particularly in large active mining areas.",
