ABSTRACT
A major problem encountered in mineral haulage from mechanised surface mines has been the production capacity loss due to the inadequate equipment operational reliability and availability. The paper introduces the application of quantitative reliability techniques and its extension to the prediction of system risk; and illustrates the comparison of performance of dragline equipment system with that of shovel-dumper combination. The methodology is simple and supported by case study analyses of Kusunda and Jayant projects of India.
