While CSV or text files are commonly used to feed input into TCL macros in Surpac, they often come with limitations—such as loss of formulas and formatting when exporting from Excel. To overcome this, a more efficient approach is to use TWAPI to interface directly with Excel from within Surpac macros. This post introduces how to implement that method.
One of the most powerful features in Surpac is its support for scripting and task automation using TCL. By utilizing the macro recording function, users can easily loop and repeat tasks—unlocking new levels of efficiency and creativity. This post explores the next step for advanced users: creating graphical data such as points, lines, and triangles directly in the workspace using TCL and SCL.
This article discusses advanced concepts in creating TCL scripts for GEOVIA Surpac, specifically how to handle an unknown number of user inputs through a dynamic form. The topic is intended for Surpac users who already have a basic understanding of TCL and SCL/GUIDO, and are interested in learning how to create an interactive table for selecting block model attributes.
The attached data package was developed to assist new users in the their understanding of TCL and SCL. The scripts complement the Surpac help descriptions, with SCL and TCL examples existing in a TCL format that can be easily executed within the Surpac GUI.
The modelling of structural geology is often an over-looked, misunderstood and under-utilized facet of the mining process, where deeper knowledge of structural trends can provide vital insights into design considerations, safety, ore genesis and structural controls on mineralization.
With the release of the GEOVIA Surpac 6.9 Structural Suite, geologists now have the capability to visualise, interpret and plot these trends. The key benefits and use cases of this toolset are outlined in the GEOVIA post, entitled ‘Extending Geology Modeling for Structural Geologists with the Surpac Structural Suite’.
For roles such as an Underground Geologist, Underground Planning Engineer or an Underground Surveyor, it is necessary to be able to view planned underground workings with existing drill holes and to view planned drill holes with existing workings.
This capability helps ensure the safety of both underground miners and workers on the surface who are operating within the area of influence from the dangers associated around drillholes in the areas of influence.
To view workings subject to exiting and planned drillholes:
Many users of GEOVIA Surpac struggle with how to effectively select specific drillholes when completing database tasks such as display, compositing or data extraction. To view or process a select number of holes requires some setup in the collar table and knowledge of Surpac’s Drillhole Constraint functionality. This is often an overlooked and forgotten area of the Surpac toolset, but yet can provide value by streamlining workflows. This GEOVIA blog post will now discuss the setup and methodology to utilise this capability.
Grade estimation for undulating or folded deposits can often be challenging. A variety of solutions can be used to reduce the bias in the search parameters during block model estimation, one of which is dynamic anisotropy interpolation.
Dynamic anisotropy interpolation is an estimation method which takes into consideration the local variation of the domain orientation into the block estimation.
Why use dynamic anisotropy?
As an underground geologist, one of the weekly jobs maybe to map the structures and lithological contacts in the development drives. This information can then be used to update grade control and resource models, geotechnical models, and help with future mine planning.
In this post we will discuss how we can bring the sketched wall mapping into Surpac.
