On this page you will find programs that I have written that can be used in mining applications, including:
Open pit optimisation using WhittleTM software is standard for almost all mine planning engineers.
Maxpit is a program I wrote many years ago that does the same job.
It solves the maximum closure problem using the max-flow algorithm.
The current program is incomplete:
But I will update this version with the final version soon.
All you need to do is create a CSV file of your regularised model.
Here are the first 10 lines of the demo file (REGM.CSV):
XC , YC , ZC , REVENUE, COST , DOMAIN, SHELL 60.0, 46.0, 26.0 , , , 3500.0, 3245.0, 350.0 , , , 5.0, 10.0, 5.0 , , , 3502.5, 3250.0, 352.5, 0.0, 2700.0, 0.0, 0.0 3502.5, 3250.0, 357.5, 0.0, 2700.0, 0.0, 0.0 3502.5, 3250.0, 362.5, 0.0, 2700.0, 0.0, 0.0 3502.5, 3250.0, 367.5, 0.0, 2700.0, 0.0, 0.0 3502.5, 3250.0, 372.5, 0.0, 2700.0, 0.0, 0.0 3502.5, 3250.0, 377.5, 0.0, 2700.0, 0.0, 0.0
The following lines contain the data for each block in the model.
I am thinking about a Widows 64 bit version that has no limits (contact me if you are interested).
If you want multiple pit shells, then re-run Maxpit with the previous output as an input using a different shell number.
Edit the PitViewer batch file to recognise the other pit shells.
If you use CAE’s Studio 2 or Studio 3 then I have a macro for converting a Datamine block model into the CSV format.
Email me on firstname.lastname@example.org if you would like a copy.
If you have downloaded the files and ran the batch file then you will have a number of pit shells you may what to view.
You can use the PitViewer batch file to examine the results. The batch file calls another program I wrote call PitViewer.
Here is a zip file with demo data.
