R E S U M O<\/strong><\/p>\n\n\n\nO desmatamento \u00e9 causado por diversos fatores antr\u00f3picos, entre eles agropecu\u00e1ria, extrativismo vegetal e mineral, considerados como um dos mais impactantes, pois, se tratando da explora\u00e7\u00e3o mineral, esta atividade consiste na retirada do material geol\u00f3gico que al\u00e9m de causar desmatamento em grande escala, gera tamb\u00e9m, impacto em sua biodiversidade e no aspecto social local. Usando t\u00e9cnicas de geoprocessamento foi realizado um estudo comparativo da rela\u00e7\u00e3o existente entre a minera\u00e7\u00e3o e o desmatamento no Munic\u00edpio de Oriximin\u00e1. A metodologia foi composta em duas etapas, aquisi\u00e7\u00e3o dos dados pelo Projeto de Monitoramento do Desmatamento na Amaz\u00f4nia Legal por Sat\u00e9lite (PRODES)\/Instituto Nacional de Pesquisas Espaciais (INPE), Instituto Brasileiro de Geografia e Estat\u00edstica (IBGE), Departamento Nacional de Produ\u00e7\u00e3o Mineral\/Ag\u00eancia Nacional de Minera\u00e7\u00e3o (DNPM\/ANM). Na segunda etapa foram utilizadas t\u00e9cnicas de geoprocessamento e posteriormente, com dados obtidos do PRODES e do anu\u00e1rio da ANM foi poss\u00edvel gerar gr\u00e1ficos da taxa de desmatamento e minera\u00e7\u00e3o. Os resultados das an\u00e1lises espaciais evidenciaram entre os anos de 2008 a 2017 a predomin\u00e2ncia de \u00e1rea desmatada ocorrendo dentro do pol\u00edgono de extra\u00e7\u00e3o do min\u00e9rio, indicando uma poss\u00edvel e significativa parcela de contribui\u00e7\u00e3o no desmatamento, na qual, denota-se no gr\u00e1fico da taxa de desmatamento no munic\u00edpio. Al\u00e9m disso, atrav\u00e9s da sobreposi\u00e7\u00e3o das geocamadas do desmatamento com os pol\u00edgonos de recursos minerais existentes, que o munic\u00edpio apresenta empreendimentos do setor mineral com destaque para a extra\u00e7\u00e3o de bauxita, cobre, ouro e sais de pot\u00e1ssio, onde, apresentam maior dimens\u00e3o da atividade mineral. Logo, \u00e9 poss\u00edvel perceber que a produ\u00e7\u00e3o mineral est\u00e1 intimamente ligada com o desmatamento, uma vez que, quando realizada de maneira n\u00e3o sustent\u00e1vel, essa atividade ocasiona poss\u00edvel degrada\u00e7\u00e3o do meio ambiente.<\/p>\n\n\n\n

A B S T R A C T<\/strong><\/p>\n\n\n\nDeforestation is caused by several anthropic factors, including agriculture, plant and mineral extractivism, considered as one of the most impacting, because, when it comes to mineral exploitation, this activity consists in the removal of geological material that, in addition to causing large-scale deforestation, also generates an impact on its biodiversity and on the local social aspect. A comparative study of the relationship between mining and deforestation in the municipality of Oriximin\u00e1 was conducted using geoprocessing techniques. The methodology was composed of two stages, data collection by the Deforestation Monitoring Project in the Amazon by Satellite (PRODES)\/Instituto Nacional de Pesquisas Espaciais (INPE), Instituto Brasileiro de Geografia e Estat\u00edstica (IBGE), National Department of Mineral Production\/National Mining Agency (DNPM\/ANM). In the second stage, geoprocessing techniques were used and later, with data obtained from PRODES and the ANM yearbook, it was possible to generate deforestation and mining rate graphs. The results of the spatial analyses showed between the years 2008 to 2017 the predominance of deforested area occurring within the mining polygon, indicating a possible and significant share of contribution in deforestation, in which it is denoted in the graph of the deforestation rate in the municipality. In addition, by overlapping the deforestation geolayers with the existing mineral resource polygons, the municipality presents mineral sector ventures with emphasis on the extraction of bauxite, copper, gold and potassium salts, Where, they present bigger dimension of the mineral activity. Therefore, it is possible to notice that mineral production is closely linked to deforestation, since, when performed in a non-sustainable way, this activity causes possible degradation of the environment.<\/p>\n\n\n\n
