Processos de desativação de empreendimentos mineiros

Abstract

Due to the necessary intervention and modification of environmental characteristics of the region for mineral extraction to take effect, the mining venture, involves the appearance of degraded areas by the end of the operation, considering that the ore extracted does not return to their place of origin. Therefore the deactivation phase of a mine, must be well planned and managed, with the aim of minimizing environmental impacts that can reach in a direct way the population surrounding the mining enterprise. Among the actions that show possible mitigating environmental impacts brought on by mining activities, the mine closure plan aims to guarantee the return of the area, once the operation of the enterprise, to a condition acceptable to regulators and users post-mining, which allows one to deploy future use. The process of deactivating a mining enterprise must consider in addition to chemical stability, biological and physical sites affected the stability of socio-economic status of the population directly and indirectly related. Stressing that the plan should be developed since the beginning of the mineral project, allowing, among other things, adequate provision of resources and establishment of financial guarantees for this milestone. This study aims to reflect on the real importance of a Mine Closure Plan and observe as it happens, in the environmental legislation.
