Ultimate Pit Limit Optimization using Boykov-Kolmogorov Maximum Flow Algorithm

A. David Mwangi; Z. Jianhua; H. Gang; R. Muthui Kasomo; I. Mulalo Matidza

Volume 12, Issue 1 , January 2021, , Pages 1-13


  The ultimate pit limit optimization (UPLO) serves as an important step in the mine planning process. Various approaches of maximum flow algorithms such as pseudo-flow and push-relabel have been used for pit optimization, and have given good results. The Boykov-Kolmogorov (BK) maximum flow algorithm has ...  Read More

ebrahim elahi; Reza Kakaie; amir yusefi

Volume 2, Issue 2 , July 2011, , Pages 118-125


  Ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. A number of algorithms such as floating or moving cone method, floating cone method II and the corrected forms of this method, the Korobov algorithm and the corrected ...  Read More

Determination of the largest pit with the non-negative net profit in the open pit mines

J. Gholamnejad; A.R. Mojahedfar

Volume 1, Number 2 , July 2010


  The determination of the Ultimate Pit Limit (UPL) is the first step in the open pit mine planning process. In this stage that parts of the mineral deposit that are economic to mine are determined. There are several mathematical, heuristic and meta-heuristic algorithms to determine UPL. The optimization ...  Read More
