Introduction
Processes TDOUT and TDIN provide the interface between your application and the standalone Whittle THREE-D program for pit Optimization.
How to use
Process TDOUT takes a Datamine model and creates two ascii output files, which can be read by THREE-D. When THREE-D is run an output results file is created. Process TDIN reads this results file, and the associated parameter file, and creates a Datamine model. This is illustrated in Figure 1.
Figure 1 THREE-D Interface - your application creates external economic and parameter files, and reads external result and parameter files.
The THREE-D economic file has a record per block with the following information:
-
Block index
-
Block value
-
Ore-body identification
The block dimensions are defined by the Datamine model cell structure. If the model has subcells the economic value for the block is found by accumulating all the subcell values. Where the accumulated subcell volume is less than the cell volume, the remainder will be estimated with the default parameter VDEFAULT.
The ore-body identification is defined by a numeric field. If a subcell model is supplied, the dominant field value is output. The information is used when printing plans and sections of results files, or to display the position of the orebody for checking purposes. Ore-body identification numbers can be in the range 0-61 to be printed with values 0-9,A-Z,a-z.
If a subcell model is supplied, it must be in sorted (IJK) order.
