Operational mining unit size (or sizes, if variable) will yield tonnes, grades, and metal of ore at given cutoffs (ore and waste) considering operating selectivity. Different orebody domains, mining configurations, and production rates affecting the OMU are also described.

We address: (a) geological elements that influence the level of selectivity during mining, and technologies that deal with waste rejection; (b) eco-friendly techniques, such as tunnel-boring ...

This research will deal with creation of methodology that will aid in selection of Selective Mining Unit through firstly creation of the model of the orebody of interest and subsequent optimization of the Selective Mining Unit size to improve recovery and eliminate dilution.

The conventional definition of the selective mining unit (SMU) is the smallest volume of material on which ore/waste classification is determined. The SMU (selective mining...

The concept of a Selective Mining Unit (SMU) is necessary to report resources from the high-resolution simulated geostatistical realizations. When simulation is performed, the traditional approach is to average the grades at high resolution to the chosen SMU scale.

A selective mining unit (SMU) may be considered the smallest volume that a mining operation can select between ore and waste (Parker, 1980). Often, the SMU size is increased to account for imperfect information at the time of mining and other considerations.

The SMU or selective mining unit refers to the minimum support upon which decisions (in particular ore/waste allocation decisions in open pit situations) can be made.

Mining selectivity is understood as the process of separating ore from waste. This concept is strongly related to four effects that imply a degradation of the operational results. These are: Support effect—the design and planning of the operation is developed on the basis of …

The calculation of mineral resources and ore reserves from a block model requires the choice of a block of selective mining unit (SMU) size. Each block is assigned a grade or a distribution of grades. The resources/reserves are calculated from these block values.

Our unconventional definition of the selective mining unit (SMU) is the block model size that would correctly predict the tonnes of ore, tonnes of waste, and diluted head grade that the mill will receive with anticipated grade control practice.
