Resumo: | The beneficiation methods used by Brazilian mining companies make the country have a significant number of dams. In this context, this work aimed to characterize these structures according to height, volume, risk category and environmental damage. For this study, we used a quantitative approach and document analysis, which consisted of examining the dam inventory for the year 2019, provided by the National Mining Agency. The results obtained indicate that in Brazil there are 769 registered dams, most of which are in the states of Minas Gerais (45.6%) and Pará (13.5%). It was noted about volume and height that small dams are the majority, corresponding, respectively, to 74.2% and 64.5% of the registered structures. In addition, it was observed that most of the tailings deposited in the dams come from clay and / or sand mining. It was noted that 53.4% of the dams were built in a single stage, however, it is noteworthy that 81 dams have no indication of the construction method employed. Regarding the risk category and associated potential damage, 217 dams are included in class “B” and 44.7% do not have this information. Miners are often required to monitor these structures along with technical inspections to reduce the risk of rupture and increase dam safety. |

En este contexto, este trabajo tuvo como objetivo caracterizar estas estructuras de acuerdo con la altura, el volumen, la categoría de riesgo y el daño ambiental. Para este estudio, utilizamos un enfoque cuantitativo y un análisis de documentos, que consistió en examinar el inventario de presas para el año 2019, proporcionado por la Agencia Nacional de Minería. Los resultados indican que en Brasil hay 769 presas registradas, la mayoría de las cuales se encuentran en los estados de Minas Gerais (45,6%) y Pará (13,5%). Se observó con respecto al volumen y la altura que las presas pequeñas son la mayoría, que corresponden, respectivamente, al 74,2% y al 64,5% de las estructuras registradas. Además, se observó que la mayoría de los relaves depositados en las presas provienen de la extracción de arcilla y / o arena. Se observó que el 53.4% de las represas se construyeron en una sola etapa, sin embargo, es de destacar que 81 represas no tienen indicación del método de construcción empleado. Con respecto a la categoría de riesgo y el daño potencial asociado, se incluyen 217 represas en la clase "B" y el 44.7% no tiene esta información. Los mineros a menudo deben monitorear estas estructuras junto con inspecciones técnicas para reducir el riesgo de ruptura y aumentar la seguridad de la presa.Os métodos de beneficiamento utilizados pelas mineradoras brasileiras fazem com que o país tenha uma quantidade significativa de barragens. Neste contexto, este trabalho objetivou caracterizar essas estruturas de acordo com a altura, o volume, a categoria de risco e os danos ambientais. Para a realização deste estudo, utilizou-se uma abordagem quantitativa e análise documental, que consistiu no exame do inventário de barragens referente ao ano de 2019, disponibilizado pela Agência Nacional de Mineração. Os resultados obtidos indicam que no Brasil existem 769 barragens cadastradas, sendo que a maioria destas estão localizadas nos estados de Minas Gerais (45,6%) e no Pará (13,5%). Notou-se com relação ao volume e altura que as barragens de pequeno porte são a maioria, correspondendo, respectivamente, a 74,2% e 64,5% das estruturas cadastradas. Além disso, observou-se que a maior parte dos rejeitos depositados nas barragens são provenientes da mineração de argila e ou/areia. Notou-se que 53,4% das barragens foram construídas em etapa única, entretanto, ressalta-se que 81 barragens não possuem indicação do método construtivo empregado. Em relação à categoria de risco e dano potencial associado, 217 barragens estão inseridas na classe “B” e 44,7% não possuem essa informação. É necessário que as mineradoras realizem com frequência o monitoramento dessas estruturas, juntamente com inspeções técnicas a fim de diminuir o risco de ruptura e aumentar a segurança das barragens.Research, Society and Development2020-02-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/247810.33448/rsd-v9i3.2478Research, Society and Development; Vol. 9 No. 3; e135932478Research, Society and Development; Vol. 9 Núm. 3; e135932478Research, Society and Development; v. 9 n. 3; e1359324782525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/2478/2008Barcelos, Gabriel Jhonatas NatalinoLage, José Rafael DuarteCordeiro, Juni Silveirainfo:eu-repo/semantics/openAccess2020-08-20T18:07:57Zoai:ojs.pkp.sfu.ca:article/2478Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:04.743186Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
