Short Courses

Short courses ran on Sunday, November 17 at the Hyatt Regency Vancouver.

Thank you to everyone that registered for a short course. They are now SOLD OUT!

1. Static Liquefaction – Comprehensive Overview and Update on State of Practice         

Static liquefaction and strength loss of tailings dams due to undrained failure has become a topic of interest in tailings management following the Fundão and Mount Polley tailings dam failures. Static liquefaction is the sudden loss of strength when loose soil, typically granular material such as sand or silty sand, is loaded and cannot drain. Strength loss due to undrained failure is also associated with fine grained materials of low hydraulic conductivity, such as clays or plastic silts. The two phenomena are related; loading and deformation produces a tendency for the materials to contract and develop excessive pore pressure faster than drainage systems can relieve the pressure. Static liquefaction is a rare event but happens very quickly and without warning, so it is an extremely dangerous phenomenon.          

This short course will present a discussion of the fundamentals of Static Liquefaction, along with an overview of the current state of practice of field and lab testing, and analytical methods. This course should be of use to practicing professionals as well as owners and regulators. Relevant case studies of failures and successes will be presented for context and discussion. An optional laboratory tour and CPT demonstration will follow.

2. Corporate Governance of Tailings Facilities – Challenges and Case Studies of Implementation

This full-day workshop will explore a range of topics related to good corporate governance and management of tailings facilities. It will begin by providing an overview of governance practices described in guidance documents developed by the Mining Association of Canada, and discussion of key challenges in implementing the updated guidance. The workshop will then further explore implementation of good governance through case studies focusing on topics including:

  • Implementation of best available technologies and practices for tailings management
  • Integrated approaches to risk to incorporate perspectives from diverse stakeholders.

The workshop will also provide an international perspective with respect to the work of the International Council on Mining and Metals on the development of international guidelines for tailings management.

3. Tailings Dam Breach Analysis – Addressing the Challenges from Owner, Regulator, Practitioner and Researchers Perspectives

This workshop will provide an overview of the technical and non-technical challenges, as faced by practitioners, owners and regulators, associated with conducting and presenting the results of tailings dam breach analyses. Dam breach analyses and inundation studies are typically conducted to determine the dam consequence classification and for emergency response planning but there are no generally accepted best practise method(s) for tailings breach analyses and thus there is a wide variation in how they are conducted and the results communicated. Case study presentations will be used to illustrate the challenges and variability of breach analyses. Forum discussions, facilitated by industry leaders, will be held in the afternoon with the goal of defining the challenges and collaboratively developing action plans to address these challenges. The workshop is intended to develop a path forward, with input from dam owners, experts, regulators and researchers.

The methodology proposed in the draft CDA bulletin will be the foundation of the discussions and this workshop will be a follow-up to the workshop held at the CDA 2019 conference (attendance at the CDA 2019 workshop is not a pre-requisite).
