The management of groundwater on mine sites has become of greater importance in recent years. Proper management is particularly important from the aspect of environmental concerns as well as its impact on slope stability and dewatering of open pits. Extending the life of existing mines is causing the need for open pits to be deeper and tailings storage facilities to be larger. This short course covers the aspects of groundwater modeling as related to problems encountered typically at mine sites.
Significant advances have been made in the application of numerical models to practical problems in geotechnical engineering. The mining area is a particular area in which numerical modeling can be challenging. Complex 3D geometries are often associated with the numerical modeling of tailings ponds, earth dams and other earth structures.
The first day of the course will start with a basic overview / refresher of groundwater seepage flow theory. The fundamentals of setting up a seepage model as well as the common issues related to 2D / 3D seepage modeling will be covered. Model setup related to typical scenarios encountered at a mine site will be covered as both 2D and 3D numerical models. Methods of representing 3D geometry for 3D modeling will be covered.
The second day will focus on unsaturated groundwater seepage, coupled climatic analysis, and large-strain consolidation analysis. The basics of performing an unsaturated analysis as well as methods for determining unsaturated soil properties will be covered. A particular focus will be the 1-D analysis of earth cover designs for the remediation of waste rock and mine tailings structures. New methodologies for analyzing large-strain consolidation of mine tailings in 1D/2D/3D will also be covered.
The applications of automatic mesh refinement techniques to practical problems in order to improve convergence and improve the accuracy of calculations will be discussed.
This course intends to provide the user with an overview of the practical applications of probabilistic principles in groundwater modeling of complex earth structures. Attendees will be provided with complimentary trial versions of the SVOffice – SVFlux groundwater software such that they can follow along during software demonstrations.
The course will be of benefit and interest to geologists; groundwater modelers; geochemists; civil or geotechnical engineers; hydraulic specialists; and mining professional, engineering, or technical specialists.
