Validating the Model

There are a number of ways to validate the model after it has been built:

Plotting in Section View Publisher

In this section we will use Section View Publisher to create a plot of the laminar model.There is a template file supplied with the laminar model demo data that you can use if you wish. Refer to the Section View Publisher Helpfor more information on creating section templates.

Single Section

To create across section plot of the model showing the modelled seams:

Select theNewicon from theToolbarto start with a blank section.

Double click theLocationbranch in the Property Tree to display theLocation property page of the Properties property sheet.

Press the<Properties>button to display the properties box (Figure 1).

Figure 1: Specifying location parameters.

Enter the parameters as shown in Figure 1.

Select the<OK> to return to theProperties property sheet.

Select theScale property page.

Enter the parameters as shown in Figure 2 and press the <OK> button to return to the main window.

Figure 2:Specifying scale parameters.

Select the<InsertModel Profile>icon from the Toolbar.

Choose the model named COAL.MOD fromthe available model files when prompted (make sure you are in the coal demo directory). Youwill then be presented with the COAL.MOD Propertiesproperty sheet (Figure 3).

Figure 3: Selecting model and display parameters.

Enter the parameters as shown in Figure 3.

Select the Colourproperty page and enter the parameters as shown inFigure 4. For this example we are only interested in the model structure.

Figure 4: Disabling colour parameters.

Select the Stratigraphy property page and enter the parameters as shown inFigure 5.

Figure 5: Selecting stratigraphies to display.

Ignore the Stripping Ratio property page tab for this example.

Click the <OK>button to return to the main windowwhich will display a plot similar to the one shown in Figure 7.

Figure 6: A single section of the model profile.

Stacked Sections

To create stacked sections:

Double-click the Locationbranch in the Property Tree to display the Propertiesproperty sheet (Figure 8).

Figure 7: Adding a new section.

Select the only location in the list and press theNew…button to copy the location.

Double-click the new copy to display the location dialog box (Figure 9).

Figure 8: Specifying new section location parameters.

Change the label name to XS1408700 to reflect the new section to plot.

Change the northing to 1408700.

Press the OKbutton to return to the Properties property sheet.

Press theOKto return to the main window which will display the two plots as shown in Figure 10.

Figure 9: Displaying multiple sections of the model profile.

PlottingDrillholes

To check that the model was constructed correctly we will plot the drillhole file used toconstruct the model. To plot the drillholes:

Select the<Insert Drillholes icon from the Toolbar.

Select the file namedREAL2.DHL to display the REAL2.DHL Properties property sheet (Figure 11).

Enter the parameters as shown in Figure 11.

Figure 10: Specifying drillhole display parameters.

Select the Stratigraphyproperty pageand enter the parameters as shown inFigure 12.

Figure 11: Selecting stratigraphies to display.

Select the Labelsproperty page and enter the parameters as shown inFigure 13.

Figure 12: Selecting thelabel to display.

Select the Planproperty pageand enter the parameters as shown inFigure 14.

Figure 13: Specifying drillholesplan parameters.

Press the <OK> button to return to the main window.

Save the fileby pressing the<Save> icon in theToolbar.

To create other sections to evaluate otherareas of the model simply use the current file andchange the locations as described above.

Plotting in PlanView Publisher

In this section we will use Plan View Publisher to create a plot of the laminar model. There is a template file supplied with the laminar model demo data that you can use if you wish. Refer to the Plan View Publisher Tutorialfor more information on creating plan view templates.

To create a plan plot of the model showing the modelled seams:

Select the<Open> iconfrom the Toolbar and choose TEMPLATE.GPL from the coal demo datadirectory. TEMPLATE.GPL is an empty plan file with pre-defined colour keys, etc.

Select theSaveicon from the Toolbarand enter a new file name. Make sure the file name is different so that you donot overwrite the template. In this tutorial we will name the GPL file UF_SEAM_CONTOURS.GPLto denote the seam being plottedand that it displays model data. You may use your own file naming criteria if desired.

Select the<InsertModel Contours>icon from the Toolbar.

Select COAL.MODfrom the available model files (make sure you are in the coal demo directory) to display the Model Contours Propertiesproperty sheet (Figure 15):

Figure 14: Selecting the model to display.

Enter the parameters as shown in Figure 15.

Select the Value property pageand enter the parameters as shown in Figure 16.

Figure 15: Specifying contour parameters.

Select the Colourproperty page and enter the parameters as shown in Figure 17. You can check the criteria and colour ranges of the key by clicking the <Properties… button.

Figure 16: Selecting the colour key.

Select the Label property page and enter the parameters as shown in Figure 18.

Figure 17: Specifying label separation.

Select the Stratigraphy property page andchoose the stratigraphy unit as shown in Figure 19.

Figure 18: Selecting a stratigraphy to contour.

Select theSaving property page and enter the parameters as shown in Figure 20. This example specifies the IMS CAD file named CONT_UF.CAD in the default IMS directory.

Figure 19: Saving contours to a CAD file.

Select the OKbutton to return to the main window which will display a plot similar toFigure 20.

Checking the Model in the Grade Tonnage Reporter

Another good check of the laminar model is to calculate the volume of the model. This is easily achieved by generating a simple volume report in the Grade Tonnage Reporting module.The module produces a report file withvolumes reported by seam. This is a quick way to check if any seams have not beenmodelled since they will appear in the volume report with zero volumes.
