Block Results

• Selected: Block results are created when you click the Create button.
• Cleared: Block results are not created when you click the Create button.

The prefix for the name of the polygon and solid files that are created.

This prefix is added to before the locations name, separated by an underscore, to create the complete file name.

The type of files created. Options are:

• Solids: Each block mined or filled is output as an object in a solids file.
• Strings: Each block mined or filled is output as a closed polygon in a string file.

Note: This option is not available if the scenario includes only underground mining locations and the mining method for all underground locations is Whole. If the scenario includes only underground mining locations and the mining method for all locations is Whole, solids are always created.

Blocks are draped vertically onto the upper and lower surfaces that are specified for each location.

When your mining method is Polygons or Whole and the top and bottom of your locations are irregular surfaces, draping blocks allows you to represent the correct volume of material mined graphically. Draping blocks on the surfaces can be useful for seam mining, where benches follow geological contacts, for example, in coal and mineral sands.

Note: This option is available when the mining method for one or more locations is Polygons or Whole.

Opens the Edit Location Geometry form.

You use this form to specify the upper and lower DTM for each location.

If you select Drape blocks on DTMs, you must specify the upper and lower DTMs for each location.

Fields on the Edit Location Geometry Form

The mining and fill locations for which you want to create graphical results files.

Tip: You can use wildcards to specify more than one location. To specify the locations using the Wildcard Expression Builder, click the Ellipsis button.

The qualities, numeric user parameters, and user calculations which you would like output to the attribute fields of the polygon files.

Notes:

• By default, the qualities, user parameters, and user calculations for material classes for which Calculate Qualities is selected are not output to the attribute fields. Qualities, numeric user parameters, and user calculations are output to the polygon files only when they are specified in the Qualities field.
• Surpac string files have a 512 character limit for the sum of all attribute field data.

Tip: You can use wildcards to specify multiple qualities. To specify the qualities using the Wildcard Expression Builder, click the Ellipsis button.

For file formats that support attribute ordering, the information found in the attribute fields is as follows:

• The first seven attributes contain general schedule information:
  • Period Number
  • Period Start Date
  • Mining Direction
  • Bench Height
  • Location Name
  • Polygon Number
  • Fraction Mined
• The eighth and subsequent attributes contain information for each material class for which you selected the Calculate qualities check box. For each material class in turn the attributes contain:
  • Material class values: the material class name, volume, and mass.
  • Quality values: the values for the qualities specified. The number of description fields used is the same as the number of qualities selected.
  • User Parameter values: the values for the user parameters specified. The number of attributes used is the same as the number of user parameters selected.
  • User calculation values: the values for the user calculations specified. The number of attributes used is the same as the number of user calculations selected.

Example

In a scenario where:

• Calculate Qualities is selected for two material classes
• one aggregate and two average qualities are defined
• one numeric user parameter is selected
• one aggregate user calculation is selected

For output to Surpac, the attributes are output to the description fields of the string file as follows:

D1 Period Number
D2 Period Start Date
D3 Mining Direction
D4 Bench Height
D5 Location Name
D6 Polygon Number
D7 Fraction Mined
D8 Material Class (1)
D9 Volume for Material Class (1)
D10 Mass for Material Class (1)
D11 Quality (1) for Material Class (1)
D12 Quality (2) for Material Class (1)
D13 Quality (3) for Material Class (1)
D14 User Parameter (1) for Material Class (1)
D15 User Calculation (1) for Material Class (1)
D16 Material Class (2)
D17 Volume for Material Class (2)
D18 Mass for Material Class (2)
D19 Quality (1) for Material Class (2)
D20 Quality (2) for Material Class (2)
D21 Quality (3) for Material Class (2)
D22 User Parameter (1) for Material Class (2)
D22 User Calculation (1) for Material Class (2)

Note: This option is not available if the scenario includes only underground locations and the mining method for all underground locations is Whole.

The number of decimal places output for the numeric values in the description fields.

Note: This option is not available if the scenario includes only underground locations and the mining method for all underground locations is Whole.

The percentage by which the block coordinate values are reduced.

The Shrinkage value does not affect the quantity or quality data written to the blocks; it controls only the size of the blocks for graphical display and plotting.

Caution: The values written to the blocks for attributes such as tonnage and volume are not affected by the shrinkage factor. However, the dimensions of the blocks are changed. If you use the block results to calculate volumetrics in a GMP, the values will be affected by the shrinkage factor.

Note: This option is not available if the scenario includes only underground locations and the mining method for all underground locations is Whole.

• Selected: Block results are created when you click the Create button.
• Cleared: Block results are not created when you click the Create button.

The workspace in the GEMS project to which you want to export the block 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.

The percentage by which the block coordinate values are reduced.

The Shrinkage value does not affect the quantity or quality data written to the blocks; it controls only the size of the blocks for graphical display and plotting.

Caution: The values written to the blocks for attributes such as tonnage and volume are not affected by the shrinkage factor. However, the dimensions of the blocks are changed. If you use the block graphical results to calculate volumetrics in a GMP, the values will be affected by the shrinkage factor.

Note: This option is not available if the scenario includes only underground locations and the mining method for all underground locations is Whole.

The fields of the GEMS workspace to which you want to output the attributes of the block results. To map the attributes to the fields, click the Ellipsis button. The Field Mappings form appears, in which you can select the fields of the GEMS workspace.

Tip: If you do not want to export one or more of the attributes, leave the Field cell empty.
