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 ...
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 ...
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
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 ...
MULTIVARIATE RESOURCE MODELLING FOR ASSESSING UNCERTAINTY IN MINE DESIGN AND MINE PLANNING
(SOUTH AFRICAN INSTITUTE OF MINING AND METALLURGY, 2012)
Beyond the mining pit: the academic role in social deliberation for participatory environmental planning
Although mining activities are required to supply human needs, the academic participation on the allocation and planning of mining activities is reduced. We presented our experience in the participatory review of Rio Claro's ...
Target Data Projection in Multivariate Visualization – An Application to Mine Planning
(Springer Berlin / Heidelberg, 2008)
Incorporation of geometallurgical attributes and geological uncertainty into long-term open-pit mine planning
(MDPI AG, 2019)
© 2019 by the authors. Licensee MDPI, Basel, Switzerland.Long-term open-pit mine planning is a critical stage of a mining project that seeks to establish the best strategy for extracting mineral resources, based on the ...
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 ...
