WEB LICENSE IMPROVEMENT
Web licenses now permit up to two instances of the software to cycle or modify models, per seat, on a single computer. Web licenses are available for 3DECFLAC3D, and PFC 7, plus FLAC 8.1 and Griddle 2. You will need to update the latest version of the software to take advantage of this. Web licenses are ideal for organizations with many users at different locations or those interested in running the software in the cloud.

FEATURED PROJECT
MODELING BLAST-INDUCED VIBRATIONS TO LIMIT DAMAGE TO UNDERGROUND STOPES
Itasca's work for the Rampura Agucha Mine (India) gained insights into how open pit blasts should be designed to better protect underground excavations. Itasca developed a numerical modeling methodology that overcame limitations (point mass, straight wave path, and homogeneous rock) and complimented the scaled distance approach. Two FLAC3D models were used to link the small-scale detonation and crushing behavior to the mine-scale stress wave propagation behavior. The modeling showed the importance of changing the blast design as the distance between the explosive and the stope decreases. LEARN MORE
 
SOFTWARE TIP
 
LIST INFORMATION
The command MODEL LIST INFORMATION shows general information about the current model state. This includes things like total cycles; gravitational constant; number of gridpoints, zones, blocks, structural elements, contacts, or balls; large strain mode; model tolerances, and more — quickly summarizing fundamental model parameters, which can be helpful when troubleshooting. PROGRAM LIST INFORMATION also provides useful information about FISH variables, memory, working directory, available modules, and more.
 
FEATURED IEP PARTICIPANT
Through the Itasca Education Partnership (IEP) - Research Program, Itasca is committed to furthering the education and research of engineering and science students. We would like to share some of their amazing work here. Itasca provides both software and mentorships for selected doctoral students.
EXPERIMENTAL AND NUMERICAL MODELLING RESEARCH INTO COAL MINE GAS OUTBURSTS AND ROCK BURSTS

Harshit Agrawal, Imperial College London (United Kingdom)

The objective of this research is to understand the mechanism of rock burst and gas outburst occurrences in deep underground coal mines. Analytical equations were developed to estimate the elastic strain energy accumulated at the active face of a retaining longwall mining panel. Mine-scale FLAC3D models were used to validate the analytical equations, optimize the mining layout (considering stress-controlled and gas-pressure-controlled mining methods), and understand the influence of lithological heterogeneity.
It was concluded that both mining methods are effective in reducing the liability of rock burst and gas outburst occurrences. The lithological heterogeneity present in the coal seam strongly affects the vertical stress, pore pressure, and gas emission rates, increasing the risk of rock bursts and gas outbursts while mining through the heterogeneous zone. The probabilistic risk assessment framework provides the probability of such occurrences at each excavation step, making it easier for mine management to forecast high-risk situations and adopt suitable control measures. LEARN MORE
