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 ...
Optimizing long-term production plans in underground and open-pit copper mines
(INFORMS, 2012)
We present a methodology for long-term mine planning based on a general capacitated multicommodity network flow formulation. It considers underground and open-pit ore deposits sharing multiple downstream processing plants ...
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 ...
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 ...
The 2020 Hpakant Jade Mine Disaster, Myanmar: A multi-sensor investigation for slope failure
(2021-07-01)
A quarry failure along the slopes of the Wai Khar open-pit jade mine in Hpakant, Myanmar has led to the deaths of at least 172 jade miners on 2 July 2020. This paper conducts a systematic investigation of the incident by ...
Block size selection and its impact on open-pit design and mine planning
(SOUTH AFRICAN INST MINING METALLURGY, 2006-03)
This work evaluates and characterizes the impact of the support size and mining dilution of a block model in the operation and selection of equipment at an open pit mine. An exploratory analysis and geostatistical modelling ...
Sustainability assessment of alluvial and open pit mining systems in Colombia: life cycle assessment, exergy Analysis, and emergy accounting
(2018-08-24)
In this doctoral thesis the sustainability of two mining systems in Colombia is evaluated; open-pit and alluvial mining from cradle to gate, through the implementation of environmental, social and / or economic indicators ...
Optimizing Long-Term Production Plans in Underground and Open-Pit Copper Mines
(2012-02)
We present a methodology for long-term mine planning based on a general capacitated multicommodity network flow
formulation. It considers underground and open-pit ore deposits sharing multiple downstream processing plants ...
Using CALPUFF to determine the environmental impact of a coal mine open pit
(WIT PressProcesos Fisicoquímicos Aplicados (PFA)Reino Unido, 2020)
Modification of Lotic Environments for Open Pit Coal Extraction: Effects on Biota and Recommendations
(Univ Nac Colombia, Fac Ciencias, Dept Biol, 2018-01-01)
Open coal mining will cause a series of modifications to different lotic environments in Colombia. In this paper we analyzed the case of an open pit coal mine located in the Department of La Guajira, Colombia, focusing on ...
