This paper describes two numerical models that were performed to study the dynamic interaction between a crusher, a mechanically stabilized earth wall and a stockpile for the primary crusher at important mining project in Peru. The models were implemented in the finite element program Plaxis 2D Read more... about Interaction Between A Crusher, A MSE Wall And Stockpile At Mine In Peru

Arenal Deeps is an Au mine located near Minas de Corrales, 400km north of Montevideo, Uru- guay. The Arenal deposit is a subvertical fault zone, 6m – 30m wide, which was exploited via an open pit op- eration from 2004 until 2009 and underground since then. Underground mining is developed using Read more... about Arenal Deeps: application of numerical methods to two- and three- dimensional stability analyses of underground excavations

Cerro Vanguardia is an Au-Ag mine located in the central plains of Santa Cruz, Argentina. The deposit consists of several veins 3.5-10m wide and 19km long, related to epithermal mineralization of the Chon-Aike formation by Jurassic volcanism episodes. The exploitation is carried out by means of Read more... about Cerro Vanguardia Open Pit Mining: Database Management for Stability Analyses

The Carena project is located at Puerto Belgrano Naval Base in Bahía Blanca, Buenos Aires Province in Argentina. The project consists of the temporary watertight closure of dry dock Nº. 2 for maintenance and repair of the dock’s infrastructure. The closure was effected by means of a cellular Read more... about Mechanical characterization of a hydraulic fill sand and FEM simulation of cellular cofferdams at Carena project

Buenos Aires, Argentina, rests on a loess deposit named Pampeano Formation. Foundations of buildings, industrial facilities, major infrastructure projects, metro tunnels and a nuclear power plant lay on this deposit. Pampeano soil is also used as a construction material for sub-bases, fills and Read more... about Small-strain stiffness of the Pampeano Formation

A numerical procedure for the preliminary estimation of the earthquake-induced settlement of concrete face rockfill dams is presented. The method is based on a simple constitutive model that accounts for the key features of the behavior of coarse grained materials that affect the response of Read more... about Numerical Assessment of the Deformation of CFRD Dams During Earthquakes
