                         minera{\c{c}}{\~a}o do Brasil. A Vale S.A. tem o direito de 
                         operar na {\'a}rea da mina N5E, onde existem produtos de 
                         altera{\c{c}}{\~a}o de rochas de baixa qualidade 
                         geomec{\^a}nica relacionados a arenitos, siltitos e cobertura 
                         later{\'{\i}}tica. Para monitorar a deforma{\c{c}}{\~a}o de 
                         superf{\'{\i}}cie, foram utilizadas 33 imagens TerraSAR-X 
                         cobrindo o per{\'{\i}}odo de mar{\c{c}}o de 2012 a abril de 
                         2013. Foram aplicadas duas abordagens de radar de abertura 
                         sint{\'e}tica interferom{\'e}trica (InSAR) avan{\c{c}}adas: 
                         DInSAR baseadas em s{\'e}rie temporal e PSI baseada em 
                         interferometria por espalhadores persistentes. Os resultados 
                         mostraram que a maior parte da mina pode ser considerada 
                         est{\'a}vel no per{\'{\i}}odo de cobertura de 
                         aquisi{\c{c}}{\~a}o das imagens SAR. No entanto, as maiores 
                         taxas de deforma{\c{c}}{\~o}es foram detectadas em locais 
                         mapeados como aterro, a norte da cava da mina, provavelmente 
                         relacionadas a mecanismos de recalque. Em outros setores onde 
                         houve subsid{\^e}ncia em baixa escala, foram mapeadas estruturas 
                         geol{\'o}gicas, indicando que as deforma{\c{c}}{\~o}es 
                         est{\~a}o concentradas ao longo de um corredor de 
                         deforma{\c{c}}{\~a}o composto por falhas, fraturas e dobras, 
                         relacionado ao Sistema de Falhas Caraj{\'a}s. Para validar os 
                         dados PSI, foram gerados gr{\'a}ficos com dados de deslocamento 
                         da medida topogr{\'a}fica de campo. Os gr{\'a}ficos mostraram 
                         que as deforma{\c{c}}{\~o}es superficiais durante a cobertura 
                         das imagens TSX-1 est{\~a}o dentro do limiar de seguran{\c{c}}a 
                         da mineradora e n{\~a}o apresentam risco de colapso. Al{\'e}m 
                         disso, a estrat{\'e}gia de medi{\c{c}}{\~a}o baseada em ambos 
                         os processamentos interferom{\'e}tricos pode ser presumida como 
                         sendo representativa do deslocamento de superf{\'{\i}}cie 
                         expresso por valores de prisma, com base na valida{\c{c}}{\~a}o 
                         estat{\'{\i}}stica. Os dados interferom{\'e}tricos forneceram 
                         uma vis{\~a}o sin{\'o}ptica e detalhada do processo de 
                         deforma{\c{c}}{\~a}o que afeta o complexo de 
                         minera{\c{c}}{\~a}o, sem a necessidade de campanha de campo ou 
                         instrumenta{\c{c}}{\~a}o. Assim, a investiga{\c{c}}{\~a}o 
                         enfatizou a import{\^a}ncia que a tecnologia InSAR tem no 
                         monitoramento. ABSTRACT: The Mineral Province of Caraj{\'a}s, 
                         Amazon region, the most important mining activity of Brazil is 
                         developed. Vale S.A. has the right to operate in the area of the 
                         N5E mine, where there are products of alteration of rocks of low 
                         geomechanical quality related to sandstones, siltstones and a 
                         lateritic cover. In order to monitor surface deformation, were 
                         used 33 TerraSAR-X images covering the period from March 2012 to 
                         April 2013. Two interferometric synthetic aperture radar 
                         approaches (InSAR) were applied: DInSAR based on time series and 
                         PSI based on Interferometry by persistent scatterers. The results 
                         showed that most of the mine can be considered stable during the 
                         coverage period of acquisition of SAR images. However, the highest 
                         deformation rates were detected in a geological unit mapped as a 
                         landfill, north of the mine pit, probably related to accommodation 
                         mechanisms. In other sectors where there was low-scale subsidence, 
                         geological structures were mapped, indicating that the 
                         deformations is concentrated along the deformation corridor 
                         composed of faults, fractures and folds, related to the 
                         Caraj{\'a}s Fault System. To validate the PSI data, graphs were 
                         generated with displacement data of the field topographic 
                         measurement. The graphs showed that the surface deformations 
                         during the coverage period of acquisition of SAR images are within 
                         the miner's safety threshold and do not present a risk of 
                         collapse. Furthermore, the measurement strategy based on both 
                         interferometric processing may be presumed to be representative of 
                         the surface displacement expressed by prism values, based on 
                         statistical validation. The interferometric data provided a 
                         synoptic and detailed view of the deformation process that affects 
                         the mining complex, without the need for field campaigning or 
                         instrumentation. Thus, the research emphasized the importance of 
                         InSAR technology in monitoring.",
