Short courses will run on Sunday, November 17 at the Hyatt Regency Vancouver and will be collaborative across the industry (e.g., include participation from owners, designers, academics, regulators, etc.) and include case histories.

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
Due to several recent tailings dam failures public scrutiny around tailings dam safety is growing which has led several jurisdictions and many mining companies to re-evaluate the state of practice in dam breach analyses and inundation studies. 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. The variations of the results of such studies has implications for downstream communities and the environment.
The CDA Mining Dam Committee has taken several initiatives in the area of tailings dam safety management including preparation of a technical bulletin on tailings dam breach analyses. The objective of this workshop is to discuss the current practice of dam breach analyses from a holistic point of view utilizing the framework proposed in the CDA technical bulletin with a goal to develop practical solutions for the mining industry. The workshop will look at the technical, regulatory and operational challenges of breach analyses and will comprise several well documented recent case studies and useful “if/else” analyses with the application of advanced technologies. The workshop is intended to develop a path forward, with input from dam owners, experts, regulators and researchers.
The workshop will be organized as a collaborative effort between dam owners, regulators, expert professionals and academia. A detailed outline of the workshop with the list of presenters will be provided soon.
