This command creates a Mining Model file (.mmd) by modeling
drillholes or processing a Geologic Model. The Mining Model adjusts
the strata elevations for recovery, minimum key thickness to mine,
minimum depth to mine, minimum separatable parting thickness and
non-key thickness to add to the key.
The input of the strata grids and the adjustments to create the
Mining Model are a similar process to the Surface Mine Reserves
command. See the Surface Mine Reserves section of the manual for a
description of the input strata grids and the adjustments.
There are a couple key advantages of applying the strata
elevation adjustments and saving them to the Mining Model. One
purpose is to save time when processing the model in Surface Mine
Reserves because the program does not need to take time to apply
the adjustments each time the model is run. Another advantage is
the mining model can be inspected with various grid tools such as
Grid Inspector to verify that the adjustments are applied
correctly.
