A new hybrid heuristic algorithm for the Precedence Constrained Production Scheduling Problem: A mining application
(Elsevier, 2020)
In this work we address the Precedence Constrained Production Scheduling Problem (PCPSP), the problem of scheduling tasks in such a way that total profit is maximized, while satisfying conditions such as precedence constraints ...

Potential local and regional impacts of particulate matter emitted from one of the world's largest open-pit coal mines
(Springer, 2018)
This study was designed to evaluate the atmospheric total suspended particle (TSP) and particulate matter (PM10) concentrations and temporal variability in one of the world's largest open-pit coal mines (El Cerrejon) located ...
Evaluating crusher system location in an open pit mine using Markov chains
(Taylor and Francis, 2017)
A methodology is presented for deciding the location of a third ore crusher to be installed at Chile’s Chuquicamata copper mine. The proposed approach determines which location alternative exhibits the minimum capital and ...
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 ...
Optimized pre-splitting model in controlled blasting to improve the speed of the slopes in the open pit mine in Perú
(International Institute of Informatics and Systemics, IIIS, 2019-01-01)
Presplitting is a controlled-blasting technique with applications in open-pit mines. The main purpose of this technique is to prevent and control overbreaks caused by excessive vibrations due to blasting. This technique ...
A framework for adaptive open-pit mining planning under geological uncertainty
Mine planning optimization aims at maximizing the profit obtained from extracting valuable ore. Beyond its theoretical complexity—the open-pit mining problem with capacity constraints reduces to a knapsack problem with ...

Mapping surface deformation in open pit iron mines of Carajas Province (Amazon Region) using an integrated SAR analysis
(Elsevier B.V., 2015-07-02)
The Carajas mineral province encompasses the world's largest iron reserves with excavation carried out through open pit benching. Mining operations in the area have significant areas of rock mass movements and surface ...
