Export String to XPAC polygons
XPAC is a comprehensive mine scheduling system created and distributed by Runge Mining. XPAC requires data representing the mining operation so that a scheduling study can be performed and so that a pictorial representation of the scheduling results can presented.
This function permits the conversion of strings into a format suitable for loading into XPAC so that a pictorial representation of the scheduling results is possible.
To run this function: Choose File > Export > String to XPAC polygons, or...
Volumes and quality/grade data may be prepared for importation to XPAC from the Block Model by a similar interface function in the Block Modelling module.
Define the strings to be converted
Location, ID Range and String Range
Some or all strings from a range of string files may be converted into the XPAC polygon file. Enter the Location and ID Range of the string files to be processed.
A blank string range means that all strings in the files will be processed. You may enter an explicit string range if only certain strings are required.
If an explicit string range is used, but some of the strings in that range do not exist, no error message will be displayed.
Both open and closed segments may be converted for loading into XPAC. Closed segments are typically used to represent the areas represented by various mining blocks. Open segments are typically used to represents features such as the centroids of mining blocks which can be used by XPAC for a variety of purposes.
Segments which are closed obtain the XPAC database identifiers from the specified description fields of the first point in the segment.
Segments which are open obtain the XPAC database identifiers from the nominated description fields from each point in the segment.
Define the XPAC polygon file to be created
Filename
Enter the name of the file which is to contain the polygon data in a format which is suitable for loading into the XPAC scheduling database.
Mining Block identifier description fields
The XPAC scheduling database is an hierarchical database which permits the subdividing of the mining operation into one or more levels or categories so that volumes and grades/qualities may by grouped appropriately. A typical grouping might be:
| Database Level | Database Level Identifier |
|---|---|
| 1 | Area |
| 2 | Bench |
| 3 | Section |
A unique identifier must be used to distinguish between different categories for each of the database levels. For example, appropriate values for the `Area' level might be, `north', `south', `east' and `west'.
The values for each of the identifiers which are required must exist in the Description fields of the strings which are to be converted into the XPAC polygon files. The maximum length of a database level identifier is 16 characters, values which are longer than this will be truncated.
Identify the description fields in the string files which contain the values which identify to which part of the XPAC database the polygons belong by entering values like `D1', `D2', `D3', etc.
