WST Course Series: Multidimensional Numerical Analysis of Densification in Tailings Deposition in Mining Structures

The mining activities for the exploration of the ore generate large volumes of tailings materials, thus requiring an adequate management that assesses the safety, capacity and time taken to deposit the tailings. Understanding the mechanical behavior of this material when deposited in mining structures is a topic that is widely studied nowadays and a challenge for geotechnical engineers. The importance of taking into account the variation of the void index, pore pressures, surface deformation are relevant results when performing this type of analysis. PLAXIS LE is capable of evaluating multidimensional scenarios for a densification analysis considering small and large deformations to simulate tailings deposition.

This online course will cover scenarios that show the capability of Bentley’s geotechnical solutions using PLAXIS LE software, presenting the procedure for analyzing and modeling densification applied to the mining industry. During the training, participants will have a review of consolidation theory, demonstrate the workflow for creating from simple models to three-dimensional models, and will learn how to analyze consolidation problems in mining structures, such as tailings dam or pit filling .

Density theory for small and large deformations
Description of laboratory and compaction tests
