Intersected Points or Intervals Generation from Pierce Point Function in Micromine

The Pierce Point function in Micromine is a powerful tool used to determine where drillholes or strings intersect a wireframe or wireframe set. This function is essential for geological modeling, resource estimation, and drillhole planning, allowing users to extract key intersection data efficiently.

To run this function, go to the main Drillholes | Calculations | Piearce Points panel.

Input

Wireframe

Users can select a single wireframe or multiple wireframes using expressions, wildcards, or predefined wireframe sets. It is recommended to validate wireframes before processing to ensure accuracy.

Drillhole or String Data

• Drillholes: Select a drillhole or trench database that contains the holes used to pierce the wireframe.

• Strings: Select a file containing strings to be used for pierce point analysis.

Output

The Pierce Point function offers two output modes:

• Events: Generates an output file containing all intersection points, including wireframe type, name, dip, and dip direction.

Here is an example of the intersected points between a wireframe and drillholes with its associated labels, coordinates and depth.

• Intervals: Produces a file with FROM-TO values for each piercing, applicable when a hole or string enters and exits a closed solid.

File Output

The output file records critical intersection data such as entry and exit depths, hole ID, dip/dip direction fields and wireframe name, which can be automatically added to the drillhole database for visualization in Vizex.
