Example: Define Multiple Material Classes in Gridded Seams

In the following example, the gridded seam model from the coal_minex demonstration data set is used.

1. Open a blank MineSched scenario.
2. In the Define Geology > Models tab, in the Models pane, click Add .

The Choose a data source... form appears.

3. Select the UNSW.B35 file, and click Open.



4. In the Material classes data grid, click the Extract from model icon .

The WEAT, WAST, and COAL material classes in the model are added to the Material classes data grid.



5. Click the Name call for the COAL material class and rename it to COAL_LG.
6. Click Insert twice to add two new rows to the data grid.
7. In one row, click the Name call and rename the material class to COAL_MG.
8. In the other row, click the Name cell and rename the material class to COAL_HG.
9. Select Calculate qualities for the COAL_LG, COAL_MG, and COAL_HG material classes.



10. Choose Spreadsheets > Enable Spreadsheet Views.
11. Choose Spreadsheets > Material Class Cutoffs, which enables the Material Class Cutoffs spreadsheet.



12. In the Setup Schedule > Locations tab, click the Cutoffs tab.

Tip: The Cutoffs tab is located in the lower left of the Locations canvas.



13. Enter the information as follows in the spreadsheet.

These three rows define that the low grade material has a yield of less than 70, the medium grade has a yield from 70 through 80, and the high grade material has a yield above 80.



14. Click Scenario > Save.
