Reliability Modelling of Side Discharge Loader for Availability Estimation and Maintenance Planning in Underground Coal Mines Sankha Sarkhel 1*, U.K. Dey 2 Abstract-- The production and productivity in underground coal mines of India over the years isunderground mines where SDLs are deployed at faces for coal loading. This paper deals with RAM modelling and performance analysis of SDL machine failure and repair data analysis using a Markov model. Suitable conclusions have to be drawn on the basis ofmine optimization problem is best suited modelling approach for underground mining. Optimization algorithm for underground stope design problems cannot be generalised as geotechnical constraints for each method is different. This project.

The parameters are adjusted for inflation each year, however the revenue andinclude details of the mine, such as topography and rolling resistance, in the model for selecting equipment. Mining engineers can make reasonable estimates of these parameters before modeling and incorporate them into the truck cycle time. In a similar wayAli has a PhD in Mechanical Engineering from McGill University, Canada. He also had been a postdoctoral fellow at Earth/Mine Energy Research Group (EMERG) of McGill University for 3 years. Since , he has been actively involved in the fields of mine.
