Planning Properties
To access this dialog:
-
Properties for your project can be defined using the Project Settings panel. Select Edit Properties in the Interrogation Rules section.
-
When defining Derived Activities, click Edit Properties.
A property is another piece of information that can be placed onto activities.
The main difference between an attribute and a property is the “scope” of the data and how it is applied to the design. A property can be extracted from the block model and then placed onto the design, or calculated, as is the case with derived activities. It can also be edited directly or be imported from another source such as an Excel spreadsheet or database.
The Properties dialog allows different activities to have different properties applied to them and even allows different values to be applied to the same properties within the same property definition. This can be used for say, applying different factors to activities associated with different areas of the mine.
The property definitions utilize filters to apply the formulae defined in the Formula column. The formula must be of a valid format. When entering the Formula, you can select both variables and functions to include in the formula, and check the current formula for syntax validity.
There are a series of default base properties which cannot be deleted or modified, but can be used as weighting values for other properties. Evaluated properties will always be weighted against Mined_Mass.
About Evaluated Properties
User properties can be optionally evaluated, and if evaluated, the property can be weighted on any field that isn't already weighted.
The Evaluation Method column determines how properties are treated:
-
Weighted: select this method, then use the Weighted On dropdown menu to pick a property in the project that isn't already weighted, or select the [Mined_Mass] or [Mined_Volume] options (the latter two will always be available).
-
Dominant: define a block model property as dominant. For example, there may be a spatial domain in the block model (STOPZONE) and you wish to report this property when evaluating stopes, in terms of the majority of the stope without weighting the property. Say, a specific stope accomodates 40% of STOPZONE = 1, 35% of STOPZONE=2 and 25% of STOPZONE=3, the stope will be reported as STOPZONE=1 after evaluation.
-
Additive: define a block model property as additive.
-
Not Evaluated: the property is not evaluated.
Property Types
There are, essentially, three different types of production field (excluding formula-based field definitions); normal, weighted and cost. For example, grade information is treated slightly differently to other properties in that this data is often weighted on other fields in the database (e.g. TONNES). This dialog allows you to define, for all non-system properties, if a property is to be weighted on another field.
Using the Edit Properties screen
Use the + or X buttons to add or remove a property from the list. You cannot create a system property, so Is System will remain disabled for the new entry.
If adding a new property, you must assign both Name and Units to it.
Note: This screen includes table grids that support multiple row selection.
