Aggregation heuristic for the open-pit block scheduling problem
(2016)
In order to establish a production plan, an open-pit mine is partitioned into a three-dimensional array of blocks. The order in which blocks are extracted and processed has a dramatic impact on the economic value of the ...
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 ...
A continuous framework for open pit mine planning
(SPRINGER HEIDELBERG, 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 ...
Operational Reliability of an Open Pit Mine – Case study in Chuquicamata Mine, Codelco Norte-Chile
(Universidad de ChileCyberDocs, 2010)
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 ...
Detection of open-pit mining zones by implementing spectral indices and image fusion techniques
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2017-04-01)
This article aims to present the results of the application of different proposed spectral indices and image fusion techniques for the detection of open-pit mining zones, located to the north-east of Antioquia, Colombia; ...
Development of a predictive model of fragmentation using drilling and blasting data in open pit mining.
This article presents predictive statistical models for fragmentation in open pit mines using drill-and-blast data. The main contribution of this work is the proposing of statistical models to determine the correlations ...
Photorealistic simulated modelling from fractals applied to mined-out pit restoration
(Universidad Nacional de Colombia Sede Medellín, 2014-08-25)
3D modelling has been used to simulate the restoration of mining environments, mainly due to ease of use. However, this technique poorly models natural structures, such as leaves, coastlines, mountain systems, etc. Recent ...
Beyond the mining pit: the academic role in social deliberation for participatory environmental planning
(2017-07-01)
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 ...
