Resumo: | The mineral sector have great importance in the Brazilian economy, however it can be seen as a villain in the environmental area, mainly due to the negative impacts caused by the disposal of tailings from mineral activities. In order to assist in the planning of risk management actions, this study tested a simplified model adapted to generate hypothetical leakage scenarios from an alumina tailings deposit, located in the city of Barcarena-PA. The simulations were carried out based on the LNEC method with adaptations for analyzing the tailings deposit. For this, tests were carried out to define the discharge intervals capable of generating spots with different degrees of risk to flooding (high, medium and low) throughout the Murucupi River. The results indicated the risk of flooding in Vila dos Cabanos, Itupanema and Laranjal. It is concluded that the LNEC method with adjustments can be used in the generation of the flooding spot of tailings deposits to identify risk areas and indicate priority areas for public sector actions, being, therefore, an important risk management tool. |

Con el fin de ayudar en la planificación de las acciones de gestión de riesgos, este estudio probó un modelo simplificado adaptado para generar escenarios hipotéticos de fuga de un depósito de relaves de alúmina, situado en la ciudad de Barcarena-PA. Las simulaciones se realizaron con base en el método LNEC con adaptaciones para el análisis del depósito de relaves, para eso se realizaron pruebas para definir los intervalos de descarga capaces de generar puntos con diferentes grados de riesgo de inundación (alto, medio y bajo) a lo largo del Río Murucupi. Los resultados indicaron el riesgo de inundaciones en Vila dos Cabanos, Itupanema y Laranjal. Se concluye que el método LNEC con ajustes puede ser utilizado en la generación del mapa de inundación de depósitos de relaves para identificar zonas de riesgo e indicar áreas prioritarias para acciones del sector público, siendo, por tanto, una importante herramienta de gestión de riesgos.O setor mineral apresenta grande importância na economia brasileira, entretanto pode ser visto como um vilão na área ambiental, sobretudo devido aos impactos negativos ocasionados pela disposição dos rejeitos oriundos das atividades minerais. Com o intuito de auxiliar no planejamento de ações de gestão riscos, este estudo testou um modelo simplificado adaptado para geração de cenários de vazamento hipotético de um depósito de rejeitos de alumina, localizado no município de Barcarena-PA. As simulações foram realizadas com base no método LNEC com adaptações para análise do depósito de rejeitos, para isso foram feitos testes para definir os intervalos de descargas capazes de gerar manchas com diferentes graus de risco à inundação (alto, médio e baixo) ao longo do Igarapé Murucupi. Os resultados indicaram o risco à inundação das localidades de Vila dos Cabanos, Itupanema e Laranjal. Conclui-se que o método LNEC com ajustes pode ser utilizado na geração da mancha de inundação de depósitos de rejeito para identificação de zonas de risco e indicação de áreas prioritárias para ações do poder público, sendo, portanto, um importante instrumento de gestão de risco.Research, Society and Development2021-07-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1760610.33448/rsd-v10i9.17606Research, Society and Development; Vol. 10 No. 9; e11210917606Research, Society and Development; Vol. 10 Núm. 9; e11210917606Research, Society and Development; v. 10 n. 9; e112109176062525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/17606/15954Copyright (c) 2021 Lariana Têka Barra de Medeiros; Aline Maria Meiguins de Limahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMedeiros, Lariana Têka Barra deLima, Aline Maria Meiguins de2021-09-12T14:28:06Zoai:ojs.pkp.sfu.ca:article/17606Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:54.951754Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
