Base Properties

The values contained in the Properties panel table fields vary depending upon if a geological evaluation has been performed.

The definition of the values are:

Field	Fixed Cross Sectionals	Outlines	Complex Solids
Mined_Mass	Insitu Tonnes	Insitu Tonnes	Insitu Tonnes
Length	Distance along defining centreline	Distance along defining centreline (only if Segment distance set >0)	Always set to 0
Area	Cross Sectional Area of defining shape. Set to 0 for Shanty backs.	The 3D area of the perimeter.	Always set to 0
Insitu_Volume	Metres * Density For Shantybacks this will be recalculated at the end of the FXS wireframing to reflect the true 3D Volume of the solid created.	Area * Height If Advanced Outlines are selected, after the Outline wireframing is complete, the true 3D Volume of the solids created is calculated.	After Walls and Points creation = 1000 After CXS Wireframing the true 3D Tonnage of the solids created is calculated.
Insitu_Mass	Insitu Volume * Density	Insitu Volume * Density	Insitu Volume * Density
Density	Default density from Design Definitions	Default density from Design Definitions	Default density from Design Definitions
Mined_Volume	Insitu Volume	Insitu Volume	Insitu Volume
Void_Volume	0	0	0
Depleted Volume (Only included if selected)	0	0	0

Once the geological interrogation has been performed, the evalg table is created. This contains the results of the Geological Evaluation. The evald table is untouched and still retains the original values before the geological evaluation.

The fields in the evalg table take on a slightly different value. If no geological interrogation is performed, the evalg table will be identical to the evald table. The following diagram illustrates the most complicated Geological Interrogation scenario:

Assume that there is Depletion being performed. The Depleted Segment has been Interrogated and then depleted in previous loops of the geological interrogation. We shall now consider the Interrogation of the solid represented by the red outline. The above terms are defined as follows:

Model Volume:- Volume of geological block model contained within the Solid.
Depleted Volume:- Volume of previously depleted solids.
Void Volume:- Entire volume of solid being evaluated less the model volume and depleted volume - ie that volume that has no Block Model cells within it.

The definition of the values in the evalg table after the geological evaluation are therefore as follows:

Field	All Design Types
Metres	As in evald
Area	As in evald
Insitu Tonnes	(Model Volume * Model Density) + ((Depleted Volume + Void Volume) * Default Density)
Insitu Volume	Model Volume + Depleted Volume + Void Volume
Density	Mined Tonnage / Mined Volume
Tonnage Factor	1
Grade Factor	1
Mined Tonnes	(Model Volume * Model Density) + (Void Volume * Default Density)
Mined Volume	Model Volume + Void Volume
Void Volume	Void Volume
Depleted Volume (Only included if selected by the user)	Depleted Volume

The Default Density in the above table refers to the Density as applied in the Design Definitions to the different design types. The Model Density (as defined in the Edit Block Models screen) is always used in preference to the Default Density should it exist in the model.

Should Formulae be applied to any of these fields, the values will not be as above, they will instead take the value from the formula. This will only occur in the scheduler - thus the project database will always contain the above results.
