description In this work the environmental impact of underground mining on water resources and its conceptual implications in Colombian are studied; in particular the implications of conceptual approaches to numerical modeling of the quantification of these impacts on water resources are subject to a comprehensive review. A model protocol is proposed to simulate the impact of water extraction from tunnels and geochemical changes on subsurface and surface water. This protocol is mainly focused on conceptual hydrological set ups that include the analysis of changes in groundwater flow paths, the induced connection of hydrogeological units previously disconnected and regional groundwater drawdown. The protocol proposed represents the starting point towards the construction of a decision support system based on the adequate quantification of the impacts that would allow us to design suitable monitoring and follow-up systems as well as mitigation and remediation alternatives. The implications of different conceptual models on numerical modeling are further studied using typical assumptions on theoretical approaches widely used in the Colombia context. The latter is performed by comparing a synthetic case of fractured media to a homogeneous porous media. Results showed the relevance of using a conceptual approach that accounts for a comprehensive geometrical characterization of the fractured system in order to simulate the actual response of the aquifer. Results also show important differences between the discrete fracture and the equivalent porous media approach that may affect the appropriate design of control and mitigation measures.

En particular, se estudian las implicaciones del uso de diferentes aproximaciones conceptuales en la modelación numérica de estos impactos. Se propone un protocolo de modelación útil para la simulación del impacto de la extracción continua de agua desde los túneles y los cambios (geo)químicos inducidos en la superficie y la subsuperficie. Este protocolo está enfocado principalmente en el análisis conceptuales hidrogeológicos relacionados con cambios en las direcciones de flujo y el comportamiento regional de los niveles freáticos comúnmente forzados por las prácticas mineras. Un protocolo de este tipo representa el punto de partida para la construcción de sistemas de soporte de decisiones que nos permitan el diseño de sistemas de monitoreo y seguimiento, así como el diseño de alternativas de mitigación y remediación. Para completar el estudio de las implicaciones del uso de diferentes aproximaciones teóricas para representar conceptualmente el acuífero asociado a una explotación minera se usa un medio fracturado creado sintéticamente. Los resultados muestran la gran relevancia que tiene el uso de una aproximación conceptual que incluya una caracterización geométrica detallada de las fracturas de tal manera que el modelo sea capaz de representar la respuesta real del acuífero. Los resultados también muestran las grandes diferencias entre el uso de una aproximación de fracturas discretas y el uso de un modelo de medio poroso equivalente, lo cual puede llegar a afectar el diseño de medidas de mitigación y control.application/pdfspaUNIVERSIDAD ANTONIO NARIÑOhttps://revistas.uan.edu.co/index.php/ingeuan/article/view/355/296https://creativecommons.org/licenses/by-nc-sa/4.0http://purl.org/coar/access_right/c_abf2INGE@UAN - TENDENCIAS EN LA INGENIERÍA; Vol. 3 Núm. 6 (2013)2346-14462145-0935Aproximaciones conceptuales hidrogeológicasminería subterráneamodelos númericosefectos ambientaleshydrogeological conceptual approachesunderground miningnumerical modelingenviromental impactsImpact of the underground mining on aquifers: perspectives in the Colombian contextImpacto de la minería subterránea en acuíferos: perspectivas en el contexto colombianoinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/version/c_970fb48d4fbd8a85Pérez, Anibal J.123456789/10432oai:repositorio.uan.edu.co:123456789/104322024-10-14 03:49:59.548metadata.onlyhttps://repositorio.uan.edu.coRepositorio Institucional UANalertas.repositorio@uan.edu.co
