- W2103739427 abstract "There are few algorithms, developed for optimisatio n of ultimate stope limits. These are either heuris tic or rigorous. The rigorous algorithms such as the appli cation of the branch and bound technique and dynamic programming approach do not apply on 3D problems. Heuristic algorithms such as floating stope of Datam ine and the Maximum Value Neighbourhood ( MVN ) algorithm do not guarantee the true optimum solution; they only provide a solution, which is close to the opti mum one. The MVN algorithm runs on a fixed 3D economic block model of the ore-body and forms the best neig hbourhood of each block in the model. The algorithm starts from the first block to form its MVN and include it into the ultimate limit. Then it pr oceeds to the last block to build up the small MVN as largely as possible. However, since it is a heu ristic approach, the final stope limit obtained may contain a number of unnecessary waste blocks, ie they may be excluded from the ultimate s tope without violating the stope constraints. In additio n, there may be a number of necessary ore blocks, e xcluded from the ultimate stope. This paper introduces the extension of the MVN algorithm to run a multiple pass and check if it is possible to remove waste blocks from the ultimate stope and add other ore blocks to it. Running the multiple pass makes the ultimate stope limits as cl ose as possible to the optimum one." @default.
