The SECTION module of the AMINE mine design software is a useful tool that allows the user to define and cut sections through 3D objects throughout the mine at any location, orientation and at any inclined angle. The program also provides a complete set of tools to modify and manipulate the sections after they are cut. The Section module plays an important role in the mine engineering environment and is designed to smoothly interact with other modules of AMINE such as the Drawings Manager and IBLAST. Typically, the Manager is used to quickly assemble 3D information of the mine such as 3D drifts of several mine levels, Geology information such as ore meshes, stope meshes or Laser Cavity surveys of adjacent mined out stopes, constitute the basic ingredients to be used by the powerful Section tools. Once the 3D information is assembled, the section Define tool is used to set the name, orientation, number of sections, the distance between them and the inclination angle. After the sections have been cut, they are ready for the IBLAST tools to be applied for production drilling and blasting design.

Defining Sections

The Section module of AMINE offers seven ways of defining a section based on their looking direction:


  • Looking North, South, East or West
  • Section by Elevation
  • Section by clicking on any 2 points in the plan view to determine a plane of cut with the possibility of typing a dump angle or by picking on 3 points in the drawing to determine the complete plane for cutting (Pt-Azm).

After selecting the type of section to be cut, the user can also specify the following:


  • The number of sections to be cut
  • The prefix name of the sections
  • The distance between each section
  • The dump angle of the sections
  • The default thickness of the sections
  • Show intersecting DDH

Examples of Sections

Here's an example of a section defined and cut using the Point-Azimuth method by picking on two points in the plan view to determine the cutting plane. On the plan view, the 3D information of 2 mine levels are assembled along with the laser cavity survey (in blue) of a mined out stope.

When defining a section by choosing the Point-Azimuth method and picking on two points in the plan view, the Section module draws a temporary yellow line to mark the plane. In addition, a yellow look arrow is also drawn to indicate the looking direction of the section. This feature allows the user to readily see if the section has correctly been defined with the desired orientation, looking direction and dump angle.

On the right you can see the result after the section has been defined and cut. All the 3D objects in AutoCAD such as meshes and solids are cut and joined together as continuous polylines. Moreover, all the lines created by the Section Cutting tool respect the original 3D objects colors.

The user can now manipulate this section. Operations that can be done to the section include flipping the view direction, increase or decrease the section thickness, navigate through each section in the drawing, editing the sections name and deleting the sections.
