1. Introduction to SGeMS

Last updated in October 22, 2019

MiningMath has been a plugin and embedded on SGeMS, allowing to visualize a model, validate it using statistics, visualize the results produced by MiningMath, among others.

2. Common Questions

2.1 How to filter results by periods?

This section shows how to filter MiningMath outputs on SGeMS to visually analyze geometric parameters, the evolution of the results across the life of mine, among others.

2.2 How to import surfaces?

The following video summarizes how you can import surfaces back to SGeMS once you close everything and without saving your project. This procedure is also applicable to importing input surfaces used as surface constraints to compare with your results.

2.3 Importing Results

This section shows how to visualize MiningMath outputs once you close everything without saving your project.

Loading a block model

To load the block model, users have two options.

Option 1

    • On SGeMS upper menu, click on Objects.

    • Then on Load Objects.

    • Find your scenario folder.

    • Select the MinedBlocks file (the same works for the AllBlocks).

    • Click Open.

Option 2

    • On the Explorer, find your scenario folder.

    • Select the MinedBlocks file (the same works for the AllBlocks) and drag it into SGeMS 3D view screen.

Visualization Setup

Regardless of the loading path taken in the previous step, it is required to set up how the data loaded will be set up.

    • Define the object type as a masked grid.

    • Define a grid name (e.g. MinedBlocks Scenario 001)

    • For X coordinate change it from IX to X.

    • For Y coordinate change it from IY to Y.

    • For Z coordinate change it from IZ to Z.

    • As a cell size, use the block size along each direction.

    • Select Use-No-Data-Value and define it as -99.

2.4 How to use Sections

The following video illustrates how you can view your project by sections.

3. Overcoming Issues

3.1 View Model Crash

This is a crash that happens on SGeMS when users click the View Model button during the importation. The following video shows a palliative solution which consists in a full scenario setup, saving, then getting back to View Model.

3.2 Unable to see results

Visualizing scheduling results on SGeMS

Sometimes, the user might face a situation where:

  • The input model or the optimization outputs are not shown properly.

  • The user is likely to see an empty black screen or a grey box (Figure 1).

Figure 1: Scheduling visualization on SGeMS shows a grey box.

Solution to view your model

The solution for such cases is quite simple:

  • For each parental box checked, check the box named Region TOPO.

  • Note: click the Earth button to refresh the visualization.

Figure 2: The solution is to ensure "Region TOPO" is checked whenever its parent box is also checked.
