Define Mining Model

This command creates a Mining Model file (.mmd) which stores a sequence of strata elevation grids along with strata attribute grids and a ground surface grid. The Define Mining Model works the same as the Define Geologic Model. See the Define Geologic Model section of the manual for a description of the functions.

The difference with the Mining Model is that the strata elevation grids are already for any adjustments including recovery, minimum key thickness to mine, minimum depth to mine, minimum separatable parting thickness and non-key thickness to add to the key. The Mining Model can be used in commands like Surface Mine Reserves and the program can directly process the strata elevation grids without having to apply those adjustments as it needs to for a Geologic Model.
