The conservation of natural resources is a fundamental issue, in addition to being, in many cases, regulated by laws and decrees. In Brazil, resolutions require a rigorous environmental impact assessment to be carried out and the EIA (Environmental Impact Study) and RIMA (Environmental Impact Report) to be generated in any projects with activities that potentially cause degradation to the environment. A widespread way of assessing environmental impacts is the interaction matrix known as the Leopold Matrix. Many scientific articles use the original or modified Leopold matrix to perform the assessment of environmental impacts, although they commonly point out disadvantages or limitations in the use of the matrix. The purpose of this article is to propose a new matrix, named "Leopold Turbinated Matrix", with the elimination of the identified disadvantages, in addition to enhancing the advantages, without visually loading the matrix, in addition to including new elements, which enhance its ability to evaluate and predict environmental impacts. For this, an in-depth study was carried out on the applications of the matrix based on national and international scientific and technological. The developed "Leopold Turbine Matrix"solve identified disadvantages or limitations, in addition to including new criteria, so that it constitutes a new powerful, efficient and comprehensive tool regarding the assessment of environmental impacts.

“…Geologicamente, o município de Pedra Lavrada integra um dos arcabouços mineralógicos mais diversificados e importantes do Brasil (Lima, 2013). Os principais problemas ambientais no Brasil, referentes à atividade mineradora, correspondem à poluição da água, ar e sonora, subsistência do terreno, incêndios causados pelo carvão, rejeitos radioativos e degradação do subsolo, ocorrente em áreas urbanas (Martim;Santos, 2013).…”

Artigo recebido em 17/08/2016 e aceito em 22/3/2017 R E S U M O Na contemporaneidade os efeitos da utilização irracional dos recursos da natureza se fazem sentir através do eminente risco de esgotamento de tais recursos, como por exemplo, a água potável, petróleo, espécies vegetais e animais. Pesquisas têm sido realizadas visando demonstrar a aplicabilidade do Sensoriamento Remoto na área geológica e ambiental auxiliado tanto na localização e determinação de depósitos minerais como também no estudo das consequências geradas a partir da exploração mineral. Deste modo o objetivo deste artigo é avaliar os impactos ambientais gerados pela atividade mineradora no município de Pedra Lavrada -PB através da utilização do Albedo da superfície, do Índice de Vegetação Ajustado ao Solo em imagens Landsat e da verificação da curva espectral indivíduos sadios e afetados por resíduos de atividade mineradora. Através dos mapas de Albedo da superfície e do Índice de Vegetação ajustado ao Solo foi observado que o entorno das Indústrias de Beneficiamento encontraram-se destacadas com valores mais elevados de albedo e mais baixos de vegetação, já ás áreas utilizadas para a extração apresentavam valores de albedo superiores a 0,301 e valores de vegetação variando entre 0 e 0,10. Também foi possível observar mudanças significativas do uso e cobertura do solo no entorno da sede municipal de Pedra Lavrada e diferenças nos valores de reflectância da curva espectral dos indivíduos afetados pelos resíduos de atividade mineradora apresentando. Palavras-chave: mineração, sensoriamento remoto, mudança de uso e cobertura do solo, espectroradiometria A B S T R A C TNowadays the effects of irrational use of the natural resources are perceived through the imminent risk of depletion of riches, such as drinking water, hydrocarbons, plant and animal species. Extensive research has been conducted to demonstrate the applicability of remote sensing in geological and environmental studies, assisting both in location and determination of mineral deposits as well as in the study of the effects and consequences generated by mineral exploration. Therefore, the main goal of this work is to evaluate the environmental impacts created by mining activities in the municipality of Pedra Lavrada -PB by using the surface albedo and the Soil Adjusted Vegetation Index on Landsat data as well as to monitoring the spectral curve of vegetation to identify the healthy and the affected individuals by mining activity waste. Through the maps of surface albedo and adjusted vegetation index for soil, the results point to an increase in the albedo nearby beneficiation Industries facilities when compared to the lowest values of vegetation, yet, the areas used for feature mineral extraction, showed albedo values exceeding 0.301 and vegetation values ranging between 0 and 0.10. It was also possible to observe significant changes in the land cover surrounding the urban areas of Pedra Lavrada, as well as differences in reflectance values of the spectral curve of vegetation affected ...
