| description | In this paper a new non-linear heuristic approach has been developed to model the variable slope angles in the open pit optimization
algorithms that is based on a simple inverse distance formulation. In the primary approaches, a fixed value of slope angle is considered and
it is usually based on special block configurations such as 1:5, 1:9 and 1:5:9 patterns that suffer from creating the higher or lower angles
than desired. The cone template based methods that were employed later, considered the variable slope angles and improved the solution
quality a little but also suffer from modeling just in non-cardinal directions. Implementation of the proposed approach on a hypothetical
block model showed its capability in generating accurate and smooth pit shapes using any number of regions with different mechanical
behaviors. |
