Técnicas utilizadas na recuperação ambiental de áreas degradadas pela mineração de calcário no município de Caçapava do Sul-RS

Abstract

The limestone mining activity is essential for the social and economic development, but this activity changes significantly the environment, causing various types of degradations through the impacts on the exploration of ore. With this, are designed the plan for the Areas Recovery Plans Degraded (PRADs) to help identify and characterize the area of the enterprise, also identifying the main impacts and the measures and techniques that should be applied to reduce them. The region of Caçapava do Sul- RS It has wide availability of limestone allowing the exploration to various mining companies. The exploration of this resource requires the occupation and use of land for the stablishment of mining activities that they are potentially degrading. This study will aim to survey the recovery techniques applied limestone mining areas on the region of Caçapava do Sul- RS. For the select of information will be made visits to main companies in the mining industry on mine areas, analysis of PRADs and interviews with technical managers of companies. With this study is expected to make a diagnosis, identifying the main degraded areas recovery techniques applied in the region of Caçapava do Sul- RS. For data collection had doing field research in four mining companies, Where interviews were conducted with responsable technical. It was request the PRAD's to analyze and take pictures. In this research were verified, that the main recovery techniques applied on Caçapava do Sul have the purpose to minimize the visual impact an avoid work accidents, planting native species around the mining rolls is one of these goal. The topographical reconditioning improve the degraded scenery and avoid slips of materials. Although the peculiarities of the emprises, don't have any meaning distinction of the recovery techniques applied in this area, they used techniques of low cost and operational.
