XPAC Export
Export EFH Values to XPAC
The XPAC Export option to compute EFH values for increments, and export them to a file suitable for import into XPAC. This option actually generates two files: <proj><name>.xpac and <proj><name>.per. They both contain the same type of information but in a different format. Examples are provided under Appendix A.
Note: This option works for increments only. Reserves must have been calculated, and faces generated and advance faces set for all blocks in the increment layer. Haulroads to exit point in the pit must also exist, that is, the Reserves, Generate Faces, Advance Faces and Haulroad options must have been carried out in the current session before using this option. A shortest path file must also exist (see Network Design ), as well as a contour triangulation of the pit. The contour triangulation is intersected with each of the mining blocks to determine the contour length of the block, and where the contour intersects with the block. This is used to determine the fill tonnage.
Instructions
On the Open Pit menu, point to Increment Design, and then click XPAC Export option
The following panel displays.
Xpac Export Option panel
Report file name
Enter the name of report. The maximum size of the file name is 20 alphanumeric characters. The full name is <proj><filename>.xpc. A file with the same name, but with the extension Per is also generated.
Shortest path file
Enter, or select from the drop-down list, the name of the file that contains the shortest path calculations. The full name is <proj><name>.spf.
Select OK.
The Multiple Selection box is then displayed. This to select haulroads by category. Cancel when finished selecting haulroads. The Exit Point Destination panel is then displayed.
For each exit point on the selected haulroads (routes) you will need to select the final destination for each material type found in the mine blocks. The final destination can be manually entered, or selected from the drop-down list.
Select OK. If there is more than one triangulation loaded, then you will be prompted to select the required topography triangulation. The report displays in the Report Window of Vulcan. The report shown is the .xpc file. Also generated but not displayed is the .per file.
