Description:
CDA’s Tailings Dam Breach Analysis Workshop is based on the Technical Bulletin: Tailings Dam Breach Analysis. The
workshop has the following objectives:
Promote the science of tailings dam breach analyses (TDBA) and build awareness on the risk of tailings dam
failures
Present and promote the use of Technical Bulletin: Tailings Dam Breach Analysis
Provide training to dam safety professionals who undertake such studies for their sites and projects
Share experiences and collect comments from participants to advance the current state of practice for TDBA
The workshop focuses on the issues and challenges that are specific to tailings dams and must be captured in such
studies. The importance of these issues has become more apparent from recent catastrophic tailings dam failures.
The main topics to be covered in the workshop are:
A brief overview of the Bulletin and TDBA process
Terminology
Failure scenarios and modes/mechanisms of tailings dam breach
Geotechnical issues of tailings relevant to TDBA
Rheological behavior of tailings
Challenges to breach modelling and outflow hydrograph/volume estimation
Selection of TDBA modelling cases
Modelling of breach runout processes (hydraulic modeling)
Geo-mechanical models and their limitations
Scope and requirements of sensitivity analysis
Inundation mapping and reporting
Common mistakes and pitfalls
Case studies based on recent failures.
Who should attend?
This workshop will be of particular interest to dam owners and operators of mining facilities, regulators, non-governmental organizations, emergency planners, risk assessors and the consultants who provide services to the owners. It is helpful if the participants already have some familiarity with tailings dam operation or management. The workshop is intended to meet requirements for continuing professional development.
