Performance evaluation of mining equipment in surface coal mine using reliability analysis

Abstract

This article deals with reliability analysis of mining equipment such as shovels and dumper in a surface coal mine at The Singareni Collieries Co. Ltd., Telangana, by using the RBD and Markov model. First, the method is to obtain the MTBF and failure rate of the individual subsystem of a shovel and each dumper using RBD. Second, the attribute of the reliability-based Markov model is dissected. The method is shown to be an effective technique to obtain the reliability of the whole system of shovel and dumper during the working period. Then, the mathematical model has written to obtain the reliability of the whole system of the shovel and the dumper is described along with its validation. The outcome shows that the reliability with a time of the entire framework is the unwavering quality incorporated of subsystems and can be treated as a factor for the optimized process of availability of the same.
