A new model for automated pushback selection
(Pergamon-Elsevier, 2020)
The design of pushbacks is essential to long-term open pit mine scheduling because it partitions the pit space into individual units, controlling ore and waste production. In this paper, a new model is proposed for the ...
Projections in the national mining development plan (nmdp) using @risk
(Universidad Nacional de Colombia Sede Medellín, 2014-10-24)
The mining industry in Colombia has reached an important position in the international market and the national economy, so, in order to describe the dynamics of the mining market, analyze the structure of the industry and ...
The role of gravity flow in the design and planning of large sublevel stopes
(Southern African Inst Mining Metallurgy, 2015)
Sublevel stoping (SLS) is one of the oldest and most used methods for underground mining. It relies heavily on the use of drilling and blasting techniques to remove the rock, and gravity to transport the broken rock to ...
Aggregation heuristic for the open-pit block scheduling problem
(Elsevier, 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 ...
A geochemical approach to the restoration plans for the Odiel River basin (SW Spain), a watershed deeply polluted by acid mine drainage
(Springer Verlag, 2017)
© 2016, Springer-Verlag Berlin Heidelberg. The Odiel River Basin (SW Spain) drains the central part of the Iberian Pyrite Belt (IPB), a world-class example of sulfide mining district and concomitantly of acid mine drainage ...
Quantifying Wet Muck Entry Risk for Long-term Planning in Block Caving
(Springer-Verlag Wien, 2018)
Wet muck entry is one of the major geotechnical risks associated with long-term production goals in cave mining. The objective of this research is to quantify the effect of the main risk variables related to wet muck entry ...
A New Algorithm for the Open-Pit Mine Production Scheduling Problem
(2012)
For the purpose of production scheduling, open-pit mines are discretized into three-dimensional arrays known as block
models. Production scheduling consists of deciding which blocks should be extracted, when they should ...
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 ...
Feasibility and cost minimisation for a lithium extraction problem
(Elsevier, 2020)
In this paper we address the problem of allocating extraction pumps to wells, when exploiting lithium rich brines, as part of the production of lithium salts. The problem of choosing the location of extraction wells is ...
A nondisruptive reliability approach to assess the health of microseismic sensing networks
(John Wiley and Sons Ltd, 2018)
Microseismic sensing networks are important tools for the assessment and control of geomechanical hazards in underground mining operations. In such a setting,
the maintenance of a healthy network, that is, one that ...
