Block model files

Block models are a required item for a site to be valid.

Importing block models

1. Check that the site status is set to Ready and click the Edit Site Block Model Files icon.
   
   The Block Model Files screen displays.

2. Click Add a new Block Model File , and select a file. The supported formats for block model file import are: 

   • CSV Block Model File (*.csv)

   • Datamine Block Model File (*.dm)

   • RPMGlobal Block Model File (*.bmdb)

   • Surpac Block Model File (*.mdl)

   • Vulcan Block Model File (*.bmf)

   • Whittle Res File (*.res)

   The RPMGlobal block model file format (bmdb) is supported from version 2.1 of RPMGlobal RESERVER. For the block model to be imported it must have been validated within RESERVER. Check your version of RESERVER to ensure the validation step has been run.

   You can import more than one file. To remove a file, select the file and click the Delete icon.

3. Select the Spatial Domain that the block model will be loaded into (if configured). The Default Domainis selected by default.

4. Principal Field Mappings, panel on right hand side of screen
   Map the Principal Fields (Code column) to the Block Model Field (column) by clicking the fxcell. All principal fields are listed; any unmapped fields will use the default value for the principal field.

   Expressions may be used to create calculated block model fields, and these fields can reference other block model fields.

   To assist with mapping click the Prefill mappings button in the upper left of the panel.

   Copy and paste Principal Field mappings - Block model mapping configuration can be copied and pasted to and from Excel. If the site is active, the mapping configuration can only be copied. To paste values from Excel, you must first stop the site.

5. The Originand Rotationsections have controls for setting the rotation angle and origin, applicable to CSV formatted block models only. Other block model formats read the settings from the block model file and hence these options will be disabled.

   The rotation angle setting instructs XECUTE to treat the data as rotated (clockwise degrees from north around the Z axis).

   Set the coordinate system of the block model centroids to either World or Local.

   World Coordinates - origin setting is disabled, rotation angle is optional.

   Local Coordinates - origin is required, rotation angle is optional.

6. Spatial Filtering [Optional], is used to filter the block model data stored in XECUTE

   

   • Click the Define Regions button (1) , then in the popup click to add a new region.

   • Give the region a name (2) and either enter the coordinates of the region bounds or click Generate from Pit Limits(3) to set the region extents.

   • If you click Generate from Pit Limits, in the dialog that opens, select the Pit Limits to include in the region (4).

   • Optionally restrict the dimensions to limit to and set buffers to apply to the extents.

   • Click the Create button (5) to close the dialog.

   • Save changes in the Define Regions popup. The applied filter regions are listed on the Block Models screen.

7. The Block Model Import Profile data maps the block definition fields to the block model field names.

   The profile can be saved for later use by entering a name in 'Save this profile as' and clicking the Add button. To update the selected import profile click the Update button.

   Enter the fields in the Block Model Import Profile. Ensure these XYZ centroid and size fields are set correctly, otherwise XECUTE will not function properly.

   

   Field	Description
   X,Y,Z Field Name	The centroid of the block.
   X,Y,Z Size Field Name	The size of the block X,Y,Z dimensions.
   Filter Field Name	The field used to filter out unwanted portions of the block model.
   Filter Values	If the value of the Filter Field equals this value ignore these blocks.
   Display Blocks Field Name	The field used in the block model visualisation Legend.

8. Click the Save icon at the top of screen to save configuration and import the block model data.

   

9. Check the Status column in the Block Model File(s) panel for the Completed status to show that the data was imported successfully.

   The Block Model Error Summary table displays any errors with the current configuration.

Online block model updates

The block models for an active site may be updated with minimal disruption for users. The updated model will use the existing import. When the block model is finished processing, the new data is pushed to any open XECUTE clients. XECUTE users are then prompted to refresh their site.

For the online Update icon to be available the original block model must exist in Model Repository. If you restored a site from a backup without the Other Sources option, the feature is disabled. To enable the feature after a restore, first add a new model using the original block model data file, reapply mappings and save. After Status is Completed and the site is in Active mode the Update icon is enabled. To remove model with disabled update icon stop the site, select the block model row, click the red - then click Save.

Update a block model by doing the following:

1. Click the checkered icon to the right of the Status column and green tick.

2. Navigate to the replacement block model. After you select the new block model the Status will show as Changed.

3. Click Save to begin the update process.

Removing block models

1. Stop the site (Ready Status).

2. Select the block model in the Block Model Files grid.

3. Click the Red - icon above the grid.

4. Click the save icon.
