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.

This study presents the effect of excavator model, loading operation location, shift availability and truckshovel combination on loading cycle time and productivity of an openpit mine. The loading cycle time was used to assess the material loading system performance which is one of the key components of the total cycle time for material transportation in an openpit mine.

and waste materials. Furthermore, the geometrical characteristics, used to design and optimise the pit, are highly relevant to the project's economics and safety, as they are associated with acceptable design criteria, which determine the stability of the open pit's walls. Among these characteristics are bench

imported into Whittle for the open pit optimisation, based on geotechnical and economic parameters derived from calculations or assembled from mines operating in Ghana. The optimal pit is then imported back to Surpac for detailed pit design incorporating a ramp and berms.

A quarry is a place where rocks, sand, or minerals are extracted from the surface of the Earth. A quarry is a type of mine called an openpit mine, because it is open to the Earth's type of mine, a subsurface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building materials.

I doubt it will be as automated as a software made specifically for pit design, but you can certainly get the job done with Civil 3D. Create a feature line at the bottom of the pit and use stepped offset to build the benches. Make a surface from those feature lines. Create a .
