PUBLICATION
"Mine simulation breakthrough could open floodgates"
David Beck and his team at Beck Arndt Engineering will continue to work on better integrating their new hydromechanical (HM) simulation capability with available mine planning tools in a bid to get the new advanced mine slope stability and water pressure modelling product as widely deployed as possible.

NEW AND UPDATED WEBSITE SECTIONS

PHOTOGRAMMETRY AND DENSE DATA CALIBRATION FOR OPEN PITS AND UNDERGROUND EXCAVATION
The problem for a very high resolution calibration of pit walls is that the relevant measurements for calibration are pit scale right down to less than bench scale. Prisms at >50m spacings are useful for inter-ramp scale or larger length scale calibration (calibration needs to sample length scales smaller than the scale of interest), but it can be hard to differentiate properties for smaller scale structure. A classic problem is the stability of pit walls around portals or other critical infrastructure – movements on all scales of structure are critical. [more]
Homogenisation and Discrete Fracture Networks
BAE has conducted extensive research in the area of rock property estimation, rock strength scaling and homogenisation. One technique applied for these tasks is numerical homogenisation. This involves constructing a model of the rock mass using a Discrete Fracture Network. [more]
New papers available in the "Downloads"-section

Multi-scale, non-linear analysis
Advances in computational efficiency and capacity mean that significant improvements in modelling practice for mines are possible. Perhaps the most significant improvement will come from a move towards calibrated, multi-scale non-linear modelling. [more]
Groud Support
Ground support, typically consisting of steel bars, cables, concrete and steel mesh, is used to support the tunnels in an underground mine. Deformation induced by mining after installation of the support and to a lesser extent, rock mass creep, cause additional loads to develop. [more]

Large Open Pit Modelling
There is a trend for open pits to be mined to greater depths than ever before. The greater depths are leading to higher underlying strains in the slope and failures arising from rock mass instability have become more prominent. These failures include instabilities resulting from the combined effects of induced slope damage and structure, as well as structurally controlled failures that pure kinematic analysis does not predict. [more]
The Application of probabilistic methods in FE analysis
The ability to quantify the uncertainty simulation results of complex large scale mining simulations is becoming increasingly important. The inherent randomness in material properties and geological parameters plays a cruital role for the interpretation of the obtained simulation results. [more]

BAE at STRATEGIC VS TACTICAL APPROACHES IN MINING 2008

Beck Arndt Engineering is pleased to confirm that we will sponsor the conference, ‘Strategic vs Tactical Approaches in Mining’ in Quebec City, Canada from September 28th to October 1st 2008.

Please visit the conference website for more information.

BAE at MassMin 2008

Beck Arndt Engineering is proud to sponsor MassMin 2008 (www.massmin2008.com).

BAE has worked with some of the worlds largest and most valuable mass mining operations, and at the BAE stand we will be showcasing our latest advances in simulation aided mining engineering. There will be examples from deep block caving to massive open stoping and technology briefs on the latest research in constitutive models, seismic forecasting and multi-scale simulation. MassMin is an opportunity to view the latest developments in engineering for mass mining techniques. We look forward to sharing experiences with you in Lulea, 2008.
