Underground

Use the Design | Underground tab to specify the stope designs to be used for regions within the optimisation region and the mining costs that apply.

Use Regions Defined By

Min/Max coordinates

Select to delineate regions for which different stope design parameters apply by ranges of coordinate values.

Wireframes of type

Select to delineate regions for which different stope design parameters apply by wireframes of a specified type.

Underground Mining Costs

Ore

Specify the cost per mass or volume incurred when mining a block as ore. This is the cost of blasting, mining and haulage of ore.

Expressions can be used to vary the cost by the depth of mining and/or the distance of the block from the plant.

Ore units

Select the units to which the Ore Mining Cost is referenced.

Diluted and recovered

Select this to specify that the mining cost for ore applies to the ore mass (or volume) after mining dilution and recovery has been included, and not to the in-situ ore mass (or volume).

Waste

Specify the cost per unit mass or volume incurred when mining a block as waste. This is the cost of waste blasting, mining and haulage. This cost is applied to the recovered material. (Dilution is not applied to waste.)

Expressions can be used to vary the cost by the depth of mining and/or the distance of the block from the waste dump.

Stope Design Regions

Specify the following settings for each region within the block model for which a different stope design is required:

Min East

(Min/Max coordinates only.) Specify the easting coordinate for the lower extremity of the region.

Min North

(Min/Max coordinates only.) Specify the northing coordinate for the lower extremity of the region.

Min Z

(Min/Max coordinates only.) Specify the elevation (Z) coordinate for the lower extremity of the region.

Max East

(Min/Max coordinates only.) Specify the easting coordinate for the upper extremity of the region.

Max North

(Min/Max coordinates only.) Specify the northing coordinate for the upper extremity of the region.

Max Z

(Min/Max coordinates only.) Specify the elevation (Z) coordinate for the upper extremity of the region.

Wireframe Name

(Wireframes of type only.) Select the wireframe of the specified type that defines the region.

Stope Design

Select the form set that specifies the requirements for the stope design applicable to the region.

Click left on the icon to select an existing form set.

Click right on the icon and select New to create a new form set. When prompted, enter the name to be assigned to the new form set and press OK.

Click right on the icon and select Edit, or press F4, to edit the specified form set.

The Stope Design and Generation form will be displayed.
