Estimation of reliability-based maintenance time intervals of Load-Haul-Dumper in an underground coal mine
Reliability estimation plays a significant role in the performance assessment of mining equipment, and aids in designing efficient and effective preventive maintenance strategies. Continuous and random/irregular occurrence of failures in a system could be the main cause for performance drop of machinery. The accomplishment of a projected level of production is possible only by an efficient oper...
متن کاملAnalysis of reliability and maintainability for multiple repairable units (Case study: Sungun copper mine)
The appropriate operating of mining machines is affected by both the executive and environmental factors. Considering the effects and the related risks lead to a better understanding of the failures of such machines. This leads to a proper prediction of the reliability parameters of such machines. In this research work, the reliability and maintainability analysis of the loading and haulage mac...
متن کاملImprovement of System Availability Using Reliability and Maintainability Analysis
Reliability is an important consideration in the planning, design and operation of engineeringsystems. As the size and complexity of mining equipment continue to increase, the implica-tions of equipment failure become ever more critical. One method to mitigate the impact offailures is to improve the reliability of the equipment. One of the purposes of system reliabil-ity analysi...
متن کاملReliability and Risk Assessment of Electric Cable Shovel at Chadormalu Iron Ore Mine in Iran
Nowadays, shovels play an important role in production of open pit mines and their failures result in significant production loss and considerable increase in maintenance costs. Therefore, reliability and risk analysis can help to improve production, productivity and reduce production costs. In this study, reliability of electric cable shovel of Chadormalu iron ore mine in Iran was investigated...
متن کاملReliability-based maintenance scheduling of powered supports in Tabas mechanized coal mine
Utilizing the gathered failure data and failure interval data from Tabas coal mine in two years, this paper discusses the reliability of powered supports. The data sets were investigated using statistical procedures and in two levels: the existence of trend and serial correlation. The results show that the powered supports follow the Gamma reliability function. The reliability of the machine de...
