Case Study Webinar FEM Analysis for Underground Mine Stability June 28, 2022 (Tuesday)
- Time 1: GMT 6am / SGT 2pm / AEST 4pm / NZST 6pm
- Time 2: GMT 11am / BST 12pm / CEST 1pm / CAT 1pm / GST 3pm / IST 4:30pm | Duration : 60 min

Underground mining at great depths is associated with the presence of high stresses in the surrounding workings in many. With the progress of mining and ever greater deposit depths, significant changes in stress and strain conditions have been observed. Such phenomena may lead to the occurrence of seismic events, rock bursts and roof falls. Therefore proper evaluation of working stability is one of the best ways to mitigate these risks.


This presentation illustrates the possibilities of reliable evaluation of underground workings stability with the use of the 3D Finite Element Method in GTS NX software.


The presented case study illustrates the condition observed in one of KGHM deep underground copper mines in which a room-and-pillar mining system is utilized.

Results in form of Safety Factor allow for the assessment of which parts of mining excavation are prone to instability occurrence, and where additional preventive actions should be undertaken.

Krzysztof Fuławka


PhD Krzysztof Fuławka is Researcher in Rock Engineering Department of KGHM Cuprum Ltd Research and Development Centre. He received his doctoral degree in Mining Engineering at Wroclaw University of Science and Technology, Poland. He also obtained a postgraduate diploma in Applied Geophysics at AGH University of Science and Technology, Cracow, Poland. In last few years, Krzysztof has participated in numerous international research and scientific projects financed by Interreg BSR, Polish National Centre for Research and Development, Horizon 2020 and EIT Raw Materials. He is an author and co-author of numerous research reports, scientific papers and pre-feasibility studies. His background is rock mechanics and numerical modelling as well as risk assessment and blasting technology. Krzysztof Fuławka is also a vice-chair of European Underground Laboratories Association (EUL).






KGHM CUPRUM supports a copper giant in the implementation of the strategy, development of a resource base, diversification of the activity and creative development, and innovative technological solutions. The activity of our Company is not limited only to the cooperation with the entities from the capital group of KGHM Polska Miedź S.A. and the copper mining region on the Fore-Sudetic Monocline. Our specialists work for bituminous coal mines in the Upper Silesia and for the Salt Mine in Wieliczka, they also take part in exploration works outside the territory of Poland. Our clients include non-mining enterprises and foreign partners with which we implement projects financed by the European Union.
