Since 1999, Knight Piésold has provided consulting services involving design of Heap Leach Pads, Tailings Storage Facilities and provision of advice on a range of S&K operational issues.
More recently, Knight Piésold has been involved with the development of conceptual closure plans and closure designs for each closure element (domain) within the S&K site. These studies have been undertaken through application of good international practice within the regulatory framework that applies in Myanmar and the management systems adopted by Myanmar Yang Tse Copper Limited (MYTCL) at the S&K mine.
Knight Piésold has reviewed site data provided by MYTCL in preparation of closure concepts for the mine site and the detailed closure design that has been undertaken for the Sabetaung open pit. The key issue to be addressed in this process is the reduction in potential for changes to parameters associated with water quality following closure.
The transition from closure concepts to closure design will be carried out by considering each specific domain and application of the conceptual objectives specified for that domain. The design is then placed into the conceptual framework to assess its conformity with the overall closure objectives. The closure designs will be progressively developed as the elements within each domain reach a point where their final design is known and conditions within the domain can be determined with sufficient accuracy to provide an acceptable level of certainty for design.
The overall closure plan will become part of the site Environmental Management System and, therefore, integrate with the other environmental management plans and the associated monitoring and reporting requirements. This will enable the potential for improved performance to be undertaken through the life of the mine and the application of research and industry development of closure to be included in plan reviews.
It is anticipated that the design of each domain will include provision for productive land use following agreement that closure objectives have been achieved.
We, at KP, look forward to our continued partnership in this closure project with MYTCL and its successful implementation.
