Equipment Selection for Surface Mining: A Review

The type of loader selected for use in a surface mine depends on the type of mineral to be extracted and speci cations of the environment, such as the bench height. We must also consider other factors in the equipment selection process, particularly, the compatibility of the loaders with selected truck eets.
