Increasing the value and feasibility of open pit plans by integrating the mining system into the planning process
(The Southern African Institute of Mining and Metallurgy, 2016)
We present a model that allows us to consider mine production scheduling coupled with the mining system at different levels of detail: from the standard origin-destination approach to a network considering different ...
Optimum ramp design in open pit mines
(Elsevier, 2020)
The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational ...
Application of optimized models through direct block scheduling in traditional mine planning
(Southern African INST. Mining Metallurgy, 2018-04)
Many papers have been published by the scientific community on the development of techniques that use direct block scheduling (DBS) to solve open pit production scheduling problems, and have compared the results obtained ...
Open pit mine planning considering geomechanical fundamentals
(Taylor & Francis LTD, 2018)
The objective of this study is to integrate the admissible factor of safety (FoS) into the mine planning. The analysis showed, as expected, that a lower net present value (NPV) is obtained with the increase in the admissible ...
A heuristic approach for scheduling activities with ‘OR’- precedence constraints at an underground mine
(Taylor & Francis, 2020)
Medium-term development planning of underground mines requires scheduling multiple activities to comply with long-term milestones, and to obtain a time span as short as possible. However, the planning must also respect the ...
The arsenic fault-pathfinder: A complementary tool to improve structural models in mining
(MDPI AG, 2018)
In a mining operation, the structural model is considered as a first-order data required for
planning. During the start-up and in-depth expansion of an operation, whether the case is open-pit
or underground, the structural ...
A continuous framework for open pit mine planning
(Springer-Verlag, 2011)
This paper proposes a new mathematical framework for the open pit mine
planning problem, based on continuous functional analysis. The main challenge for
engineers is to determine a sequence of nested profiles maximizing ...
Assessing the impact of geologic contact dilution in ore/waste classification in the gol-gohar iron ore mine, southeastern Iran
(MDPI, 2020)
Since the Gol-Gohar iron ore mine (GGIOM), which is located in southeastern Iran, is currently one of the biggest iron mines in this region, increasing the accuracy of its mineral resources model has become a challenge for ...
Stochastic open-pit mine production scheduling: A case study of an iron deposit
(MDPI, 2020)
Production planning decisions in the mining industry are affected by geological, geometallurgical, economic and operational information. However, the traditional approach to address this problem often relies on simplified ...
Antithetic random fields applied to mine planning under uncertainty
(Elsevier Ltd, 2018)
Traditional practice in mine planning often relies on estimation techniques that fail to account for the intrinsicuncertainty of geology and grades, which may have significant consequences in the mine operation. Dealing ...
