Optimum ramp design in open pit mines
(Elsevier, 2020)
The problem studied in this paper is that of designing the optimal open pit haulage ramp that, for a given ramp width and a maximum ramp gradient, connects two points of the mine, minimising construction and operational ...
Model for monitoring socioenvironmental conflicts in relation to the emission of particulate matter in the prehauling phase of a surface mine in Peru
(Springer Verlag, 2019-01-01)
This research will focus on proposing a model based on surveys conducted among people of the affected area. The questions were classified by indicators and variables selected to generate solutions to reduce social conflicts, ...
Monitoring of surface deformation in open pit mine using DInSAR time-series: A case study in the N5W iron mine (Carajás, Brazil) using TerraSAR-X data
(2014-01-01)
We present an investigation of surface deformation using Differential SAR Interferometry (DInSAR) time-series carried out in an active open pit iron mine, the N5W, located in the Carajás Mineral Province (Brazilian Amazon ...

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 ...
Environmental study of gold mining tailings in the Ponce Enriquez mining area (Ecuador)
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
As a result of the artisanal mining activities in Ecuador (specially in Ponce Enriquez mining area, province of Azuay), great quantities of mining wastes have been disposed, usually without adequate management standards. ...
CHSMST+: An algorithm for spatial clustering
(2017-06-07)
Spatial clustering has been widely studied due to its application in several areas. However, the algorithms of such technique still need to overcome several challenges to achieve satisfactory results on a timely basis. ...
