Workshop on Tailings Dam Breach
The Canada Peru Chamber of Commerce and Anddes, jointly organized the Workshop on Tailings Dam Breach Analyses, which was held on January, 29-30, 2024. The main theme of the workshop was the use and application of the technical bulletin elaborated by the Canadian Dam Association (CDA), considering the specifc conditions of each dam, in order to classify them and plan for emergencies.
The CDA specialists in charge of the workshop, Mamum Al-Mamum, Director and Principal Consultant - Dam, and Violeta Martin, hydro-technical engineer, were part of the team that prepared the TDBA technical bulletin.
The workshop was focused on the problems and specific challenges of tailings dams, with the objectives of promoting the scientific aspects of breach analyses, raising awareness of the risk of failure, and advocating for the use of the technical bulletin. Additionally, it aimed to provide training for TDBA dam safety professionals to conduct such studies on their projects, share experiences, and gather feedback from participants to advance the current state of TDBA practice.
The main themes that were developed:
-
A brief description of the Bulletin and the TDBA process.
-
Terminologies
-
Tailings dam failure scenarios and failure modes / breach mechanisms.
-
Geotechnical aspects of tailings relevant to TDBA.
-
Tailings rheological behaviour.
-
Challenges for breach modelling and hydrograph/outflow volume estimation.
-
Selection of TDBA modelling cases.
-
Modelling of the breakout process (hydraulic modelling).
-
Geomechanical models and their limitations.
-
Scope and requirements of sensitivity analysis.
-
Flood mapping and reporting.
-
Common errors and pitfalls.
-
Case studies based on recent failures.
