Introduction
|
This is a Superprocess and running it may have an effect on other Datamine files in the project. More... |
This process allows the modeling and evaluation of cut and fill volumes, based on original and updated wireframe surfaces (DTMs).
How to use
Both cut and fill volumes will be separately evaluated, and both will be described in an output block model, whose block sizes are controlled by an input block model prototype. This input prototype can also define a rotated model structure, which will be honored as supplied.
A supplied cut attribute field is used for the assignment of the cut and fill volumes. The user therefore supplies the name of this new (numeric) field, and what values will be assigned within 'cut' blocks and 'filled' blocks. This enables clear identification of cut and fill volumes, for both evaluation and plotting/display purposes.
An optional perimeter file may also be supplied, to split the cut and fill volumes into separate regions for evaluation purposes. This allows the cuts to be evaluated in separate mining strips or partitions. These perimeters are treated as boundaries as viewed in an XY plan i.e. the elevations of the perimeters are ignored. If such perimeters are supplied, an optional attribute field can also be defined, to further divide the evaluation data as required.
The degree of accuracy is controlled by the supplied cell splitting parameter. This parameter is utilized in exactly the same manner as the SPLITS parameter in the TRIFIL process.
Density values must be supplied for the cut and fill material, for use in the subsequent tonnage calculation. These values will also be placed into the density field (whose name is user-defined) of the output cut/fill block model.
The output results file contains all the evaluated tonnages and volumes, split by cut, fill and perimeter attribute. This results file is automatically also written out as a .csv file, for easy import into spreadsheet programs.
