Process Overview

Create a Datamine model from a Whittle FOUR-D results file.

The processes FDOUT and FDIN provide the interface between your application and the standalone Whittle FOUR-D program for pit optimization.

The process FDOUT takes a Datamine model and creates two ASCII output files, which can be read by FOUR-D. When FOUR-D is run an output results file is created which can be read by FDIN along with the associated parameter file. A Datamine model is created.

Your application creates external model and parameter files, and reads external result and parameter files. All optimization procedures are carried out within Whittle FOUR-D

The FOUR-D results file has a record per block with the following information:

Block coordinates - IX, IY, IZ
Total tonnes of ROCK in the block
Mining cost adjustment factor
Processing cost adjustment factor
Parcel information
Pit number.

The block model origin and cell structure is defined by the FOUR-D parameter file. The only additional field created in the output model is PIT for the Pit Number.

The process will read fixed format or comma separated results file formats.

The output model file is not written in IJK order, and must subsequently be sorted.

Output Files

Name	I/O Status	Required	Type	Description
OUT	Output	Yes	Undefined	Output model file.

Example

!FD IN &OUT(lg4model)

Enter FOUR-D parameter file name:

>SYSFILE> run1.prm

Enter FOUR-D results file name:

>SYSFILE > model2.res

>>> 6000 RECORDS PROCESSED : TIME 14:12:12 <<<

6250 blocks read and then written to model file.

>>> 6250 RECORDS IN FILE LG4MODEL <<<
