Calculating True Vein Thickness

In many scenarios, vein thickness plays a critical role, especially when dealing with narrow vein environments. Understanding the thickness of veins enhances targeting precision. To achieve this, we follow a systematic approach in our Vein Modeller:

Generate Wireframes: Ensure the generation of both Footwall (FW) and Hanging wall (HW) wireframes as outputs, alongside the vein itself.

Comparing Wireframes: Utilize the 'Comparing Wireframes' under Wireframe > Calculations > Compare Wireframes. Create comparisons between FW vs. HW and HW vs. FW. This process involves establishing an attribute, the offset distance for each vertex on both sides of the vein. Essentially, this attribute represents the thickness. Make sure the “Signed distance” option in the form is not selected.

Color Coding: Color code each side of the vein (HW and FW) based on the previously recorded thickness.

Export: Wireframes: Export all three wireframes (HW, FW, and Vein) in Micromine format, ensuring both triangle and vertex attribute options are selected.

Merge Wireframes: Use the 'Merge' tool under File > Actions > Merge. Perform two merges: first, HW with Vein, and then FW with Vein. This process transfers the thickness attributes to the vein. Key fields for merging are X, Y, and Z coordinates, and the merge field is the thickness from both HW and FW, stored as an attribute on the vein.

Import Vein with Thickness Attribute: Import the vein containing the thickness attribute, making sure to include vertex attributes. Choose the Micromine format during import.

Color Coding by Thickness: Now, the wireframe can be color-coded based on the thickness attribute.

This method enhances the visualization and analysis of veins in geological modeling. It provides valuable insights into vein thickness, aiding decision-making processes in various applications.
