Abstract:
The Telfer gold-copper mine is located in the East Pilbara region of Western Australia and is owned by Newcrest Mining Ltd. Newcrest has invested considerable time, cost and effort into mine closure planning throughout the life-of-mine. A major program of closure works is currently being undertaken at Telfer including waste rock landform reshaping, drainage management and revegetation works. Robust closure designs and documentation have been developed to support effective closure works at Telfer; a key component of this documentation is the specification of construction standards. A quality management program has been developed and implemented to verify that closure works have been completed in accordance with the specified construction standards or to identify where remedial works are required. An important characteristic of the quality management program is that it can be employed without undue impact upon critical path for the closure works. This paper explores the quality management controls that have been implemented at Telfer and their efficacy in achieving a high standard for closure works.
