Practice First

1. How to run a Scenario

Reach out to our knowledge base home page if you wish for a quick introduction to MiningMath and DBS technology prior to the hands-on approach.

On MiningMath's interface, you will find the Marvin block model and its scenarios (Figure 1). It is possible to preview the scenario and its parameters before opening it (Figure 2).

Choose and open Base Case, click the "Overview" tab (Figure 3) to check the parameters, and then click on "Run" to run the optimization (Figure 4).

After that, a short report with the results will be generated. To view it, check all the boxes on the "Load Options" window and click on "Load" (Figure 5).

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 into 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

After optimizing your block model and running your scenario(s), MiningMath generates standard output files with detailed reports. The main files have a universal format (.csv), which allows you to easily import them onto other mining packages to start your mine design and further steps of your projects.

To open the project folder, click on the scenario's name with the right button of your mouse and choose "Show in the Explorer". The optimization's main output files are:

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

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

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

2.2.1. Scenarioname.xlsx

Provides you with a short report with the main results of the optimization: several charts and sheets in which you can analyze the production on each period, the stockpiles by periods, the average grade of processes and dump, NPV per period, the cumulative NPV (Net Present Value), etc.

2.2.2. MinedBlocks.csv

This file offers a detailed report of all the mined blocks and their specificities: information on the mining sequence based on each block extracted, along with mined and processed periods, destinations, economic value, and all information used for the optimization. This file also allows you to identify blocks that were stocked and the algorithm decision-making process.

2.2.3. Surface.csv

The surface scenario brings a grid of points generated through the pit of each period: each surface is named according to its mining periods and contains information about the topographic coordinates at that time. 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.
