Optimal Selection of Selective Mining Unit (SMU) Size Abstract

The conventional definition of the selective mining unit (SMU) isthesmallestvolumeof material on which ore waste classification is determined [1]. The reality is more complex. It is impractical and impossible to freely select an SMU of ore in the midst of waste just as it is impossible to freely reject an SMU of waste in the midst of ore.
