Practice First

1. How to run a Scenario

On MiningMath interface's, you will find the Marvin block model and its scenarios, you can preview the scenario and its parameters before opening it.

Choose and open scn01-BaseCase, click on the "Overview" tab to check the parameters, and then click on "Run" to run the optimization.

After that, a short report with the results will be generated, and to view it, check all the boxes that the "Load Options" window and click in "Load".

2. Results of the Optimization

By default, MiningMath generates an Excel report summarizing the main results of the optimization. It also creates outputs of mining sequence, topography, and pit surfaces in .csv format so that you can import them easily in other mining packages.

2.1. Viewer

The 3D viewer enables the view of your model from different angles. The block colors are defined accordingly with each property displayed, varying from blue to red (smallest to largest), due to destinations, periods, or any other parameter. Therefore, it's possible to filter the blocks by the period in which they were mined or processed, for instance. In addition, it also allows you to compare multiple scenarios by loading different cases and using the left bar to change from one to another.



2.2. Output Files

To open the project folder press the right button of your mouse in the scenario name and choose the "Show in the Explorer" option. The main output files of the optimization are:


  • MinedBlocks.csv: Detailed report which presents all the blocks that have been mined.

  • Scenarioname.xlsx: Short report with the main results.

  • Surface.csv files: Grid of points generated through the pit each period.

2.2.1. scn01-BaseCase.xlsx

Several charts and sheets in which you can analyze the production in each period, the stock process by periods, the average grade of processes and dump, NPV per period, the cumulative NPV (Net Present Value), etc.

2.2.2. MinedBlocks.csv

Information on the mining sequence based on each block extracted along with period mined and processed, destination, economic value, and all the information used in the optimization. This file also allows us to identify blocks that were stocked and the algorithm decision making process.

2.2.3. Surface.csv

The surface files are a point set numbered according to the mining periods and contain information about the coordinates of the surface blocks. These files can be imported into the viewer separately so that you can verify and validate your data before starting the optimization process.

Note: The surfaces are exported/imported from/at MiningMath in Coordinates.
