Merging Seams In Laminar Models
INTRODUCTION
IMS generates a laminar model for the currently loaded model definition by merging a set of surface
files. Each named seam in the model definition has an associated surface file that is specified in the
model definition (Figure 1).
Figure 1: Surface names in the model definition
Surface files contain information about the structure of a seam and the assays/qualities in that seam.
IMS supports the following operations:
1. View the surface files in the 3D View Pane.
2. Edit the structure and assays/qualities.
3. Regenerate surface files with new input data.
4. Trim (via a region plan file) and merge surface files to create the laminar model.

BUILDING SEAMS
Procedure
1. Load a model file and a drillhole file by dragging them from the File Explorer Pane to either
the 3D View Pane or the Loaded File Pane (Figure 2). It is assumed that an adequate
number of runs have been performed to interpolate seams in the drillhole file.
Figure 2: Loaded model & drillhole file
2. Select the <Model><Laminar Model Operations><Build Surface Files> menu item. This
will display the first page of the surface files wizard (Figure 3).

3. Select the stratigraphic units you want to model by selecting the required check boxes or by
pressing the <Select Ore> button. Use the <Select All>, <Select None> and <Reverse>
buttons to make quick modifications to the check boxes.
On the initial model build, all ore stratigraphic units defined for the model must be modelled.
If you subsequently change the parameters for one or a few of the stratigraphic units, you can
nominate those units to be rebuilt here. The nominated units will be regenerated and then
recombined with existing, unaltered surface files at the end of the model build.
4. Press the <Next> button to display the Region page (Figure 4).

5.
Specify the area of the model to be built by specifying the required rows and columns.
Column 1, row 1 is the bottom, right hand corner of the model and is the base point. Columns
are numbered right to left.
You must build the total area if you are building the surface files for the first time.

Press the <Next> button to display the Mapping page (Figure 5).

7.
Drag the drillhole assays and drop them on the corresponding model assays. This allows you
to selectively modify the structure and assay/quality parameters within existing surface files.
If you have not built the model before (the surface files do not exist) then you must select all
the qualities and tick the Update structure (roof and floor) check box.

Press the <Next> button to display the Report page (Figure 6).

9.
Specify a name for the report file and press the <Finish> button.
Output
IMS will create the required surface files and display the report file (Figure 7).

NOTE: Percentages below 100 may indicate that further work is required to define that
particular parameter in the model data. If the model area has been defined as greater than that
for which data is available then the percentage of model area built will always be less than
100% unless the 'extrapolation' option is specified (see the Model Definition manual).

MERGING SEAMS
This option should only be used when no further alterations to the surface files are necessary and you
wish to create a new model from the surface files. This situation can arise when:
1. You have altered surface files using <View/Edit Triangle files...>.
2. You have added or deleted some stratigraphic units from the model (via the model
definition).
3. New subcrop, barren area or region plans are to be applied (see the Model
Definition manual).
4. You are working with multi-stratigraphic unit models (in certain circumstances).
5. You are making a revision which you wish to check before incorporation.
IMPORTANT
Be careful not to combine surface files created from different model definitions. This can occur if the
same file names are specified in more than one model definition.
Procedure
To only merge surface files without building any of the stratigraphic grids:
1. Load a model file by dragging it from the File Explorer Pane to either the 3D View Pane or
the Loaded File Pane.
2. Select the <Model><Laminar model operations><Merge surface files...> menu item.
Output
IMS will now merge the surface files applying the region, barren area and subcrop plan files as
appropriate.
The original surface files remain on the disk for subsequent modification and re-merging into revised
models. Retain these files until you are certain that you do not want to make any further modifications
to the model.
NOTE: Check the final model to ensure that the stratigraphic units and qualities/assays have been
modelled correctly.
