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 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 ...
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 ...
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 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 ...
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 ...
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 ...
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 ...
Using CALPUFF to determine the environmental impact of a coal mine open pit
