In this thesis, we study the openpit design problem, the openpit mining scheduling problem, and the openpit design problem with geological and price uncertainty. These problems give rise to (mixed) discrete optimization models that in reallife settings are large scale and computationally challenging.

I recently requested an upgrade to the Open Pit > Open Cut Design > Pit Topography tool. Basically, what the tool does is an automated boolean of two triangulated surfaces: a pit design and an existing topography. The result can give one or all of three things: a new surface topography, a mined solid or an intersection of the two surfaces.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process.

Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks are found near the surface.
