– Sunday 11 June (Full day)
Risk Assessment is a well-documented process that has been used for several decades in many industries including water supply, irrigation and hydropower dams. Although risk assessments for tailings dams are mandatory in many jurisdictions and the Global Industry Standard on Tailings Management (GISTM) requires risks to be reduced to as low as reasonably practicable (ALARP), there is currently no specific guideline available for risk assessment of tailings dams.
The new ICOLD Bulletin 194 partly addresses the issue by providing an overview of the typical risk assessment process. However, for further details the reader is referred to applicable ICOLD and national guidelines, which were primarily developed for water storage dams.
The members of the ICOLD Committee L – Tailings Dams and Waste Lagoons – are currently considering whether and in what form ICOLD can assist tailings practitioners in developing risk assessments of tailings dams.
The course objective is to present the current state of practice of Risk Assessment for tailings dams, building upon the principles outlined in Bulletin 194, with the view to improve the safety of tailings operations across the world. Group activities will provide an opportunity for the attendees to engage in the key risk assessment activities including hazard and failure mode identification, risk analysis, evaluation of the risk magnitude and consideration of reasonably practicable measures to address risks.
The intended audience of this course includes dam owners, regulators, authorities, designers and consultants, contractors and NGOs.
Content / Program (full day)
The course will cover aspects such as;
• Importance of understanding risk assessment objectives
• Key steps in the risk assessment process
• Clarification of risk tolerability concepts
• Identification of risk control measures and their verification
• Evaluation of what is reasonably practicable
• Integration of risk assessment into tailings management systems
The short course is arranged by SwedCOLD and ICOLD Committee L – Tailings Dams and Waste Lagoons and the presenters will include the members of Committee L as well as industry experts in risk assessment.
The short course convenors are Andy Small, Klohn Crippen Berger (KCB), Canada and Jiri Herza, Czech Technical University, Czech Republic.
