EMBREA-MUD

Although the failure of a tailings dam can have disastrous consequences, up to this date it had not been possible to accurately simulate them. EMBREA-MUD is a model developed by HR Wallingford with the aim of filling the gap that arose during the development of DAMSAT when the team was analysing the potential impacts associated to the failure of tailings dams.

The model is a two component breach modelling tool that simultaneously takes into account outflows of both water and mud (i.e. tailings). The model can also represent erosion of dam material by both water and tailings, erosion of tailings by water as well as the dynamic forces between water and tailings layer.

Dr. Mohamed Hassan of HR Wallingford presented a paper about EMBREA-MUD in INCOLD 2021. The paper aims to describe the details of the EMBREA-MUD model and its application to a number of test cases including the well-known case of Mount Polley.

Latest publications

We are pleased to announce that our most recent article: “A Two-Fluid Simulation of Tailings Dam Breaching” has been published in the Water Mining and the Environment Journal. This work presents the development and application of a dam breach model, EMBREA-MUD, which is able to simulate the failure of tailings dams and the behavior of liquefied fluids. It is worth mentioning that this one of models used in DAMSAT to estimate the potential risks and consequences associated to the failure of the tailings dams.

Also, last month a group of HR Wallingford published an article in the Special Edition of Tailings Dams of the Water Mining and the Environment Journal called: “DAMSAT: an eye in the sky for monitoring tailings dams“. This publication explains how the methods developed in DAMSAT can help government authorities, owners and mine operators to reduce the risks and increase the sustainability of the mining industry.

Furthermore, a group of HR Wallingford in collaboration with the University of Oxford wrote an article titled: “The potential to reduce the risks posed by tailings dams using satellite-based information“, published in the International Journal of Disaster Risk Reduction in August 2019.

This paper describes how an EO-based service allows the cost effective monitoring of tailings dams, and also helps to forecast any potentially risk associated to these structures several weeks in advance. The article also examines, how these systems could help low income countries to adequately monitor mining operations, whilst allowing timely preventative interventions to be made where the probability of failure is found to be high.

Consulta pública de la Norma Global de Relaves

Global Tailings Review es un proyecto liderado por el Consejo Internacional de Minería y Metales (ICMM), en asociación con el Programa Ambiental de las Naciones Unidas (UPEP) y Principles for Responsible Investment (PRI).

El proyecto está trabajando en una Norma Internacional buscando establecer un estándar internacional que mejore la seguridad y el manejo de los depósitos de relaves. El borrador de la Normativa puede ser descargado en español en nuestra página de Recursos.

Global Tailings Review ha lanzado una consulta pública abierta a profesionales, instituciones públicas, comunidades locales e inversionistas para obtener comentarios y sugerencias acerca de esta Norma. A través de este proceso de consulta pública, el proyecto aspira producir un documento robusto y creíble, que logre ser ampliamente implementado por la industria minera en la mayor brevedad posible.

Para participar en la consulta, visite https://globaltailingsreview.org/consultation/es-consulta y complete el cuestionario que puede encontrar en español. La consulta se encuentra disponible en varios idiomas y estará abierta al público hasta el 31 de diciembre de 2019. El documento final será publicado a principios del 2020.

Global Tailings Standard public consultation

The Global Tailings Review is a project led by the International Council on Mining and Metals (ICMM), partnered with the United Nations Environment Programme (UNEP) and the Principles for Responsible Investment (PRI). The Global Tailings Review aims to stablish an international standard that improves the safe and secure management of mine tailings facilities.

The Standard compels stakeholders to implement best practices in the planning, design, construction, operation, maintenance, monitoring, and closure of tailings facilities. The Global Tailings Review has considered the technical aspects of tailings storage facilities, and has recently launched a public consultation to enrich the draft.

The consultation aims to collect feedback from professionals, public authorities, local communities and investors. By reaching out to many experts and communities as possible, the Review intends to produce a robust and credible standard that will be taken up by the industry as broadly and quickly as possible.

The standard draft is available in our Resources page. To participate in the consultation, visit www.globaltailingsreview.org and complete the questionnaire. The consultations is available in many languages and it will be open until the 31 December 2019. The final standard will be published early in 2020.

This is an important step towards preventing catastrophic failures of tailings dam and improving the life of vulnerable communities. Once tailings facilities moved from concept to reality, they become a hazard that must be managed accordingly. The Global Tailings Review calls for innovation within the industry and the application of new technologies to minimise the risk of failure of tailings storage facilities.
