reliability analysis of a mine production system

Reliability analysis of a mine production system-a case ...

Jan 28, 1993 Abstract: At the LKAB Kiruna Iron Ore Mine in Sweden, reliability and maintainability analysis techniques have been gradually accepted as standard tools for planning and operation of automatic and complex mining systems since the mid-1980s. The reliability analysis and modeling of the production system at the Kiruna mine are discussed. Since a large number of random variables
