Reliability analysis as a tool for surface mining equipment evaluation and selection

摘要

Current trends of increased size, complexity, and automation of surface mining equipment necessitate more comprehensive and objective techniques for equipment comparison and selection. The field of reliability analysis provides tools to generate quantitative bases for maintenance and reliability aspects of such comparisons. Results from statistical analyses of failure and repair time data are used to per-form the comparison. A case study is presented which analyzes five machines of two different technologies and three different designs.
