Determining an optimum long term production schedule is an important part of the planning process of any open pit mine; however the associated optimization problem is demanding and hard to deal with as it involves large datasets and multiple hard and soft constraints which makes it a large combinatorial optimization problem.Methodology for a Dump Design Optimization in Large-ScaleMethodology for a Dump Design Optimization in Large-Scale Open Pit Mines Jorge Puell Ortiz Department of Mining and Geological Engineering University of Arizona Tucson AZ 85721 USA;Applications of simulation and optimization techniques inAPPLICATIONS OF SIMULATION AND OPTIMIZATION TECHNIQUES IN OPTIMIZING ROOM AND PILLAR MINING SYSTEMS by ANGELINA KONADU ANANI A DISSERTATION Presented to

Open-pit mining is an operation in which blocks from the ground are dug to extract the ore contained in them and in this process a deeper and deeper pit is formed until the min-ing operation ends(PDF) Optimum design of open pit minesOptimum design of open pit mines Article (PDF Available) in Bulletin of the Australian Mathematical Society 43(02):349 - 350 · April 1991 with 4938 Reads How we measure 'reads'Optimising Open Pit to Underground Cut-over: PartA common approach to determining open pit to underground cut-overis to focus on the economic size of the open pit. Consideration of underground mining is secondary and is based on the remaining resource outside this pit. This is the simplest approach. It can be determined using any one of a number of commercially available pit optimization
A common casualty of modern open-pit mine optimization is the assurance that the resulting design is actually achievable. Optimized mine plans that consider value and a bare minimum of precedence constraints do not in general translate into practical operational mineOptimized design of drilling and blasting operationsDrilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive system.[PDF] A continuous model for open pit mineThis paper proposes a new mathematical model for the open pit mine planning problem based on continuous functional analysis. The traditional models for this problem have been constructed by using discrete 0-1 decision variables giving rise to large-scale combinatorial and Mixed Integer Programming (MIP) problems. Instead we use a continuous approach which allows for a refined imposition of

Open-pit mines that manufacture building materials and dimension stone are usually referred to as quarries. People in few of the English-speaking countries are not likely to make a difference among an open-pit mine and other kinds of open-cast mines like quarries borrows placers and strip mines.ECONOMIC ASSESSMENT AND MINE PRODUCTION OPTIMIZATIONresource. Both are linked to the optimization of profits which in mineral operations is done by optimizing the ore cutoff grade considering the block model geometry.
