Sophisticated Geological Modeling

One of the unique features available only within GALENA is in the area of material profiles and slope surface definition, a feature that recently led one observer to candidly comment to us, "I can see why GALENA walks over everything else available for the mining industry." And that was after a brief 15 minute presentation!

GALENA enables you to define the soil or rock composition of a particular problem independently of the structure or excavation being considered for rapid assessment of design options.

The slope surface is entirely independent of the material profiles in terms of definition and can be moved without changing, moving or re-defining any of the material profiles that represent the material layers or geology.

What that means for you is time saved not having to re-define or change your material layers every time you want to change the slope surface, which is the way it should be - stability analysis shouldn't be an uphill battle!

We should emphasis here that it is not necessary for the user to remove or strip away any of the profiles or materials that lie above the slope surface at any time - it is handled entirely and automatically by GALENA.

To better understand this feature have a look at the following on-screen images:

This image shows the model initially with geology defined first (using profiles); material properties have been defined for each material type (color bands on each profile represent the material type associated with that profile); and labels have been added to aid identification.

Then, as shown in the image below, the slope surface is defined (based on the mine plan in this case) - expected or known water conditions are then defined along with an expected failure surface for analysis. It should be noted that the slope surface is not tied to any of the material profiles.

Once complete the model can be processed. The result is then displayed as shown in the image below.  (Trial roadway loadings were added subsequent to the first analysis.) Material profiles above the slope surface have been ignored and are not shown without intervention or any required action from the user.
