Project Description When starting a new mine, whether it's a open pit or an underground mine, the designer faces many challenges! One of these is the understanding of rock mass conditions and how this affects the choice of mining methods and the mine design at an early stage.

Project Description The Kevitsa open pit mine has been in operation since 2012 and was acquired by Boliden in 2016. A new strategic plan is currently being developed to investigate an increase in production. In conjunction with this, the geotechnical slope design parameters for the final pit depth, including a possibly deeper pit, need to be analyzed. OFFICE Chile Itasca Chile SpA Sweden ...
Project Description This project involved simulating the proposed open pits and underground mining of the Aurora Mine in Guyana, predicting potential inflow rates into the pits and underground workings, and providing pore‐pressure distributions to the geomechanical model. OFFICE U.S. Denver Itasca Denver, Inc. INDUSTRIES CLIENT NAME Guyana Goldfields LOCATION Guyana ...
Project Description Boliden is investigating the Laver low-grade copper deposit for potential future mining. The old Laver deposit was discovered in the 1930s, and was operated between 1938 and 1946. Mining was primarily conducted as small-scale underground mining, but a small open pit was also in operation at that time. The currently investigated deposit is of larger scale and with lower ...
Project Description The Ernest Henry Mine is a large open pit copper mine with deeper mineralization that was targeted for underground mining. A Feasibility Study (FS) was conducted to evaluate the potential for mining of the underground component by sublevel‐caving methods. The FS required the consideration of groundwater, including an evaluation of the expected inflows to the access ...
It has become common practice to create a three-dimensional (3-D) geomechanical model for the analysis of rock stability. One of the key inputs for a geomechanical model is the 3-D pore-pressure distribution. ...
Results of the numerical experiment show that the hybrid ANN-GA model based on the displacement back analysis can effectively recognise the horizontal in-situ stresses and natural fracture properties from wellbore deformation during drilling.Keywords: petroleum geomechanics, in-situ stress, natural fracture properties, wellbore displacements, back analysis, artificial neural ...
Challenge: The low lying area, primarily consisting of sandy/silty ground, provided a geomechanical challenge in addition to the numerous footings/piers that were required to support the structure and eliminate settling. ...
