Reliability and Maintainability Analysis of LHD Loader at Saoner Mines, Nagpur, India

In this era of intense economic competition as well as harsh and complicated environmental conditions, it is of utmost importance to achieve the high productivity and production of the mining equipment. This paper strives to analyze reliability and maintainability of Load, haul and dump (LHD) machine and to compute inherent availability of LHD machine in Saoner Mine Nagpur India. In this paper, renewal process is used for the modelling of the mechanical failures of the LHD. The validation of data whether it is independent and identically distributed (IID) is done by assessing the presence of trend and serial correlation with the help of graphical method. The parameters of various distributions were found by using Math Wave Easy Fit 5.6 professional software. Chi-square test has been applied for selecting the best fit distribution model. Further the study of the two parameter log normal distribution theory and its parameters is presented using log normal probability theory. The study reflects that analysis of reliability is a powerful tool for determining the intervals of maintenance.
