Openpit mining is a surface mining operation whereby ore, or waste, is excavated from the surface of the land. In the process of digging the surface of the land, a deeper and deeper pit is formed until the mining operation ends. It is usually suitable to determine the final shape of the pit before the mining operation starts.
