Abstract: Concepts of compatibilization between mining industry and environment are presented to contribute for the establishment of a theoretical and applied framework for conservation and preservation practices in areas with environmental restrictions. Due to the social and environmental pressures that are increasingly affecting most mining projects, those procedures, which now may be considered as special,

Non-destructive tests are among the main tools for quality control and material inspection and are widely applied in sectors such as the nuclear, petroleum / petrochemical, aerospace, steel, naval, electromechanical and paper and cellulose industries. These contribute to the quality of goods and services, cost reduction, accident prevention, environmental preservation,

The piezoelectric effect was discovered by Pierre1 and Jacques2 Curie in 1880. The two researchers carried out an experiment that consisted of cutting a crystalline sheet of quartz and then applying mechanical loads to the two opposite faces of that blade, over and over again. After the application of the forces, the appearance of electrical charges was observed; a positive face
