Edit Stope Designer project

You can use this function to change the Stope Designer settings.

Prerequisites: You are in stope design mode. That is, you have run INIT STOPE.

To run this function: Choose Design > Stope Design tools > Edit Stope Designer project, or...

In the Function Chooser, type STOPE PROJECT EDIT, and press ENTER.

Fields on the Start Stope Designer project form, Project definition tab

Field	Description
Project name	The name of the stope design project file. This is an .sdproj file. It stores the parameters of the stope design project, which you can set by running INIT STOPE or STOPE PROJECT EDIT. Project name is also the name of the .swa file that is created when you save the stope design project. Tip: If you have run STOPE PROJECT EDIT and you change the Project name, you will create a new .sdproj file.
Planes group	The planes group that contains the planes you will use for stope design.
Created design object
Extrude using	start and end planes: When the design stope is created, the stope extends to the edges of the corridors of the Start plane and the End plane that you selected. planes containing digitised polygons: When the design stope is created, the stope extends to the edges of the corridors of the planes on which you digitised polygons.
Start plane	The first plane on which to digitise a polygon - that is, the plane you will use when starting to create the stope.
End plane	The plane at the other end of the stope. This field is available only if you selected start and end planes.
Object ID	The object number of the design object - that is the solid that you will create when you run STOPE OBJECT CREATE.
Name	The file name of the design object.
Colour	The colour of the design object.
Working layer	The name of the layer to hold the polygons you create. To create a new layer, type a new name.
Ore body orientation for polygonal evaluation	The projection direction of the polygon is perpendicular to the plane unless a Dip and Dip direction is set
Dip	A positive Dip makes the projection slope upwards from a position perpendicular to the plane. A negative Dip makes the projection slope downwards.
Dip direction	The number of decimal degrees of rotation of the slope, in a clockwise direction, where 0 is orthogonal to the defined plane.
Report Settings
Report filename	The name of the stope design report, which is created at the same time as the design object.
Format	The file format of the report.

On the Block Model tab you can specify a block model that provides input to stope design so that you can see details such as grade and contained metal of each part of the stope you are creating.

Fields on the Start Stope Designer project form, Block Model tab

Field	Description
Evaluate using block model	Allows you to use the attributes in an open block model to provide grade and density for the stope slicing report.
Block model	The block model you want to use to provide data for the stope.
Specific gravity by	attribute. The density value is taken from the attribute defined in the Attribute field. value. A constant value for the density is taken from the Value field.
Attribute	The attribute, in the block model, that stores density.
Replace negatives with	Any negative value in the density attribute in the block model, is replaced by the Replace negatives with value. For example, if you have some air blocks, in the model, that currently have a negative density, you might use a Replace negatives with value of 0.
Value	The density of the blocks in the block model. You use either Value or Attribute. You cannot use both fields.
Use partial percentages	Selected: Stope design uses sub-blocking to include data from blocks that are partially within the object you are working with, but whose centroids are outside the object. Cleared: Stope design includes data from blocks only if the block centroids are contained within the object you are working with.
Precision	The number of times each block is split into 8 subblocks. Precision level 1 means that Surpac splits each block into 8 when sub-blocking. Precision level 2 means that each of the first 8 subblocks is split into 8 more subblocks, giving 64 subblocks. The sub-blocks that are within the stope provide their data to the stope design report.
Ore/rock type attribute for classification	This optional field allows you to specify an attribute that indicates whether a block is ore or waste. The stope design report then shows how much ore, and how much waste, is in each stope. The attribute must have a type of character, integer, or be a calculated attribute that evaluates to a character or integer.
Attributes	The attribute that stores the resource grade. You can add additional rows for each additional resource of interest.
Contained metal factor	A number that is multiplied by the grade when the stope design report is produced. Usually Contained metal factor is 1. Contained metal factor is useful if you need to convert grade from one unit of measurement to another, for example from ounces per tonne to grams per tonne.
Metal units	The unit of measurement that you would like to appear in the stope design report in the column that shows the weight of resource in each stope.
Replace negatives with	Any negative value in the resource grade is replaced with the Replace negatives with value. This is useful when a negative grade in the block model has been used to mark a block as waste. In that situation you could use a Replace negatives with value of 0.

Output

The .sdproj file that contains the Stope Designer settings is saved with the new settings that you defined in the Start Stope Designer project form.
