Software Tutorials
FLAC3D 7.0 Geometry Painting Tutorial
This tutorial will show how to paint zone data onto an imported geometric surface in FLAC3D.
MINEDW Tutorial (Part 4: Meshing)
In this tutorial we will go over meshing, from the creation of a 2D mesh and how to import it to MINEDW, to the inclusion of topography, layers, and pinch-outs to different areas of interest in the model.
Tutorial: Simple Slope Stability
Using UDEC 6 and the shear-reduction method to calculate the factor-of-safety, this tutorial will show you how to analyze the stability of a simple slope containing: (1) no discrete jointing (continuum), (2) fully-continuous jointing (discrete blocks), and (3) noncontinuous, en echelon jointing.

Caving in the Fabian Orebody —from Mining Stope to Cave Crater in Malmberget
The Fabian orebody is a non-daylighting iron orebody in the LKAB Malmberget Mine in northern Sweden. During 2010, a prognosis of the cave development in the Fabian area was developed, based on compilation and analysis of all available material. In March 2012, a new cave crater formed on the ground surface above the Fabian orebody, similar to what was predicted. The prognosis is compared with observations of the caving and the differences and implications quantified. A program for continued monitoring of mining-induced deformation in Malmberget is also described and a criterion for allowable mining-induced surface deformations is proposed.
Packer Testing Program Design and Management
Hydraulic testing using wireline deployed water-inflated packers is becoming a common practice for groundwater characterization at mining sites.
Use of a Finite Element Code to Model Complex Mine Water Problems
Numerical models are now used routinely to predict ground-water inflows to both surface and underground mines and to help design dewatering systems.
