Conceptual study of open pit transition depth determination through comparative analysis of open pit and underground mine production scheduling at Kibali gold mine in DRC, Africa
In recent years, a certain number of open pit mines have transitioned to underground. The open pit to underground transition problem is one of the hot topics in the mining industry that has not been mathematically solved yet. Currently there is no mathematical algorithm that can successfully optimize the transition depth by considering the life of the mine schedule of both open pit and underground all together. Due to the complexity of the problem and its size, often the transition depth is defined by considering the open pit and the underground separately. Usually the transition depth is defined ...
