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... https://www.rxkaitori.com/product-category/plc-led-replacements/
