Introducción Los botaderos de roca estéril y desmonte son estructuras enormes. El minado de carbón con voladura de montañas en British Columbia está creando las más grandes estructuras hechas por el hombre sobre la faz de la tierra. Estos inmensos botaderos miden hasta 400 metros de alto, contienen más de mil millones de metros cúbicos de material y, por lo general, forman pilas de desmonte en medio del valle o drenajes de roca. La inestabilidad de las estructuras ha generado gran preocupación entre los operadores de las minas y los entes reguladores del gobierno debido al riesgo contra la seguridad del personal, equipo e infraestructura, así como su impacto ambiental. A mediados de 1990, los representantes de la industria, Canada Centre for Minerals and Energy Technology - CANMET (Centro Canadiense de Tecnología para Energía y Minerales), el Ministerio del Medio Ambiente y el Ministerio de Energía, Minas y Recursos Petroleros conformaron un Comité de Investigación de Botaderos para promover el trabajo de investigación y garantizar el entendimiento común de estos botaderos. El curso "Diseño y Operación de Grandes Botaderos" se basa en tres documentos que se generan a partir de una serie de estudios dirigidos a mejorar el entendimiento del comportamiento y desarrollar una base de datos consistente para botaderos ... Manual de Investigación y Diseño (1991), Manual de Operaciones y Monitoreo (1991) y Revisión y Evaluación de Fallas (1992). Los consultores geotécnicos y los representantes de la industria más prominentes contribuyeron con su experiencia para llevar a cabo estos estudios. Los estudios están siendo ampliamente distribuidos por el Ministerio de Energía, Minas y Recursos Petroleros con la esperanza de que sea útil en todo lo relacionado a botaderos mineros para que sean estables, seguros y económicamente factibles. Un completo curso y referencia técnica para operadores de mina y consultores en las áreas de investigación, planeación, diseño, operación y monitoreo de botaderos de mina. Incluye la revisión y análisis de los tipos de fallas de mina. Authors Tim Eaton MSc P.Eng (Editor) Scott Broughton (Co-Autor) Klohn Crippen Berger (Co-Autor) Piteau Associates Engineering Ltd.

La mayoría de las minas produce relaves, el producto final que resulta de la extracción del cuerpo mineralizado, el procesamiento del mineral y la recuperación de minerales y metales valiosos. Los relaves son el producto de desecho que se genera a partir de la extracción, la trituración, la molienda y el tratamiento químico del mineral. Este curso se centra en los relaves como parte del proceso de minería, tipos y características de los relaves, tipos tranques de relaves y sus componentes, diseño de tranques de relaves, desempeño, construcción, operación y cierre, todo esto ilustrado con historias de casos. Este curso está dirigido a cualquier persona involucrada en los distintos aspectos de los relaves mencionados anteriormente; se incluyen ingenieros, ambientalistas, geólogos, operadores y reguladores.

Mining involves the design, construction, operation, and closure of many geotechnical structures, including: access roads, structural building pads and foundations, ponds, tailings facilities, heap leach pads, and waste rock dumps. Geosynthetics are polymeric materials used extensively in mine geotechnical structures to enhance the performance of such structures. Geosynthetics are used in conjunction with soils and rocks to increase the overall strength of these materials, to control seepage from mine wastes and through soils and rocks, and to separate soils of different gradation and hence to limit piping and potential failure of soil structures. This course introduces you to the types of geosynthetics used in mine structures, to the ways in which geosynthetics may be used to build safe mine structures, and to the many details that will make it possible for you to use geosynthetics at your mine to reduce costs and protect the environment. This course describes many case histories of the successful use of geosynthetics in mining, thereby introducing concepts, ideas, details, and practical applications that you may copy or adapt to the specifics of your mine's needs and facilities.

This introductory course is intended for anybody involved in mining who has to manage, review, pay for, design, construct, operate, or close a geotechnical structure at a mine. Included in the mining-related geotechnical structures you will study in this course are the obvious: tailings impoundments, waste rock dumps, and heap leach pads. Once you have finished this course you will know enough to deal with anything on the mine that is made of soil, rock, and those modern materials called geosynthetics. This course is not intended to make you into a geotechnical engineering specialist. It will introduce you to and provide you with plenty of practical information and knowledge about those aspects of geotechnical engineering that occur at every mine. This includes geotechnical characterization of a site, soil characterization and properties, the design of geotechnical structures, and the construction, operation, and closure of mining facilities made or consisting of soil, rock, and geosynthetics. The following primary aspects of geotechnical engineering are covered for each of the major geowaste structures at a mine: Site Exploration Soil Characterization Soil Performance Design and Construction Operation of Mine Geowaste Facilities Closure of Mine Geowaste Facilities Summary of Geotechnical Factors The course includes numerous case studies from the author's extensive experience.

In this course, we focus on groundwater theory and practice applicable to mines and the specifics of open pits, shafts, underground mine workings, heap leach pads, waste rock dumps, and tailings impoundments. We discuss, for each of these facilities, the principles of groundwater and facility design & operation that apply and must be implemented to control and protect groundwater and surface water. This course is one of a series of related courses, some of which are still in development, including Groundwater in Mining Surface Water Management at Mines Mine Water Balance Analysis Authors Jack Caldwell   Duration 14 Hours Access 90 Days Category Geotechnics Level Specialize Version Date January 22, 2016   ​Need to train a team?

The scale and nature of mining projects may result in impacts to the receiving environment, including groundwater resources. These impacts need to be quantified before undertaking the project and throughout the mining lifecycle to ensure regulatory compliance, project sustainability, and environmental protection. Common groundwater impacts associated with mining projects may include: aquifer drawdown and/or reduction in groundwater flow due to pumping from groundwater production wells and/or dewatering of open pit/underground workings; loss of groundwater discharge to surface water such as springs, lakes or streams (of particular significance during winter baseflow conditions) due to aquifer drawdown/dewatering related to mining activities; seepage and associated contaminant transport from mine waste units such as waste rock piles, heap leach piles, tailings storage facilities, backfilled and/or flooded pits/underground workings; and off-site migration of contaminant plumes in groundwater aquifers (originating from mine waste units) and potential discharge of contaminants into the receiving surface water (springs, lakes or streams). The use of numerical groundwater models enables decision makers to study and evaluate potential impacts of large and complex mining projects. Sophisticated models and modelling platforms are, however, no guarantee of good modelling practice. The complexities of groundwater models used for impact assessment may even lead to misuse and/or misinterpretation. This course on groundwater modelling describes the broader concepts of groundwater modelling related to impact assessment for mining projects. Yet, these guidelines reflect generally accepted best practices in groundwater modelling and as such should be applicable to a wide range of groundwater modelling applications. This groundwater modeling course is based on the British Columbia Groundwater Modelling Guidelines which were commissioned by the British Columbia Ministry of Environment (BC MoE). This course has been modified and condensed to suit the format and (international) audience of an Edumine course.
