End of Period Surface Results
End-of-period surface results create string and solid files which represent the pit floor at the end of each period. If you are scheduling with fill locations, the dump surface at the end of each period is also created. One string and one solid are created for each period. Creating Surpac format end of period surfaces is useful if you want to create contour maps of the bench faces, which you can do in Surpac using the end of period surface results files.
Note: You can create end of period surfaces results only if the scenario has Surface or Surface and Underground configuration.
The fields in the End of period surface section are the same for all output formats except GEMS. The first table describes the fields in the section for all files except GEMS. The second table describes the fields in the section for GEMS.
Fields on the End of Period Surfaces Section of the Graphical Results Tab
| Field |
Description |
| Active |
- Selected: End of period surfaces are created when you click the Create button.
- Cleared: End of period surfaces are not created when you click the Create button.
Note: Creating end of period surfaces can require significant processing and memory resources, especially if the Grid spacing you specify is small. It is recommended that end of period surfaces are created only once, using the final schedule.
|
| File prefix |
The prefix for the name of each surface and solid file created for each scheduling period.
This prefix is added to the period number to create the complete file name.
|
| File type |
The file format to which you want to save the end of period surfaces results. |
| Grid spacing |
The grid spacing in the X and Y directions.
The grid spacing affects the level of detail of the end of period surfaces. The larger the grid spacing, the smaller the processing and memory requirements to create the end of period surfaces.
Tip: It is recommended that you first create the end of period surfaces with a grid spacing four to five times the mining block size, to check the location geometry is correct. You can then produce the end of period surfaces with a grid spacing that is closer to the mining block size.
|
| Location geometry |
Opens the Edit Location Geometry form.
You use this form to specify the upper and lower surfaces for each location. The end of period surfaces are created from the upper and lower surfaces.
Fields on the Edit Location Geometry Form
| Field |
Description |
| Name
|
The location name. |
| Upper DTM
|
The surface that is the upper limit of the location.
You can type the file path and name of the surface or click the Ellipsis button to use the Choose a Geometry form to select the surface.
|
| Lower DTM
|
The surface that is the lower limit of the location.
You can type the file path and name of the surface or click the Ellipsis button to use the Choose a Geometry form to select the surface.

Fields on the End of Period Surfaces Section of the Graphical Results Tab for GEMS
| Field |
Description |
| Active |
- Selected: End of period surface results are created when you click the Create button.
- Cleared: End of period surface results are not created when you click the Create button.
|
| Target workspace |
The workspace in the GEMS project to which you want to export the end of period surfaces results.
To select the workspace, click the Ellipsis button. The Select a GEMS target project form appears in which you select the GEMS project, and then the Workspace Browser form appears, in which you select the workspace.
|
| Period name field |
The GEMS triangulation name to which the period number is saved. |
| Grid spacing |
The grid spacing in the X and Y directions.
The grid spacing affects the level of detail of the end of period surfaces. The larger the grid spacing, the smaller the processing and memory requirements to create the end of period surfaces.
Tip: It is recommended that you first create the end of period surfaces with a grid spacing four to five times the mining block size, to check the location geometry is correct. You can then produce the end of period surfaces with a grid spacing that is closer to the mining block size.
