Equipment Reliability: An Indicator For Sustainable Development In Mining

Modern mines possess a wide variety of capital intensive equipment. Equipment failures and the associated down time contribute significantly to the overall maintenance, operating and production costs of a mine. Reliability investigations are becoming a standard practice, as the equipment becomes more complicated and the effective use of resources is critical for achieving higher productivity and mine safety. In view of the recent global initiative for sustainable development in the mineral industries, reliability of capital intensive machinery should be considered as a key indicator for sustainable development and growth. This paper discusses the application of equipment reliability as a sustainability indicator and proposes a methodology for its practical use. Reliability of equipment systems is useful for product life cycle assessment, mine performance measurement and evaluation.
