Monitoring of non-linear ground movement in an open pit iron mine based on an integration of advanced DInSAR techniques using TerraSAR-X data
(2016-01-01)
This work presents an investigation to determine ground deformation based on an integration of DInSAR Time-Series (DTS) and Persistent Scatterer Interferometry (PSI) techniques aiming at detecting high rates of linear and ...
Optimizing open-pit block scheduling with exposed ore reserve
(2016)
A crucial problem in the open pit mining industry is to determine the optimal block scheduling, defining how the orebody will be sequenced for exploitation. An orebody is often comprised of several thousand or million ...
OpenFOAM applied to the CFD simulation of turbulent buoyant atmospheric flows and pollutant dispersion inside large open pit mines under intense insolation
(Elsevier, 2014)
The particular conditions of air circulation inside large open pit mines under intense insolation, dominated
by mechanical and buoyant effects, are crucial when studying the dispersion of pollutants inside
and outside ...
Development of a predictive model of fragmentation using drilling and blasting data in open pit mining
(2017)
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 ...
A framework for adaptive open-pit mining planning under geological uncertainty
(Springer, 2020)
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 ...
Radionuclides (222Rn, 226Ra, 234U, and 238U) Release in Natural Waters Affected by Coal Mining Activities in Southern Brazil
(2017-01-01)
Water quality was evaluated in a coal mining area in the city of Figueira, Paraná State, Brazil, where uranium was associated with the coal deposit. Upstream the mine, groundwaters were more acid and some elements and ...
