On the 23rd of February, the DMC team visited the KGHM Polkowice-Sieroszowice mine and had the opportunity to discuss the issues related to the Lekatech Electric Hammer (LEH) assembly in the operational conditions of an underground mine.
We are extremely proud of our friends from Fondazione Bruno Kessler for deveolping such an amazing technology of handheld SLAM (simultaneous localization and mapping) device based on stereo vision. Look at these examplary results.
Are you interested in portable and lightweight 3D mapping technologies? Check out the results achieved by the 3DOM unit of FBK Trento our partner and coordinator of the AMICOS project, with their hand-held stereo-based V-SLAM (simultaneous localization and mapping) solution.
23-25 June 2021, the Conference of PhD Students and Young Scientists was held. The conference enables young scientists from all over the world to exchange scientific and technical experiences and ideas in four thematic panels – Mining, Earth and Space Sciences, Geoengineering, and Geoinformation. The research results of DMC members have been published as part of the IOP Conference Series: Earth and Environmental Science in 11 articles.

On 18 November 2021, an interdisciplinary scientific conference entitled: “Innovation in the copper industry” was held, organized by Jan Wyżykowski University and Centrum Badań Jakości sp. z. o.o. The theme of the conference concerned the presentation of research and project work related to the development of the copper industry. During the event, Professor Radosław Zimroz in his presentation “Interdisciplinary research and technology development at the GGG PWR Department for sustainable use of raw materials on the example of KGHM Polska Miedź S.A.”, presented innovative solutions from the project: OPMO, AMICOS, and SafeMe4Mine.
You can now enjoy a new short movie summarising the recent effects of our work on developing prototypes of mobile inspection robots in the scope of the AMICOS project, and trying them out in various scenarios. The potential of implementing mobile robotics in the assessment of technical conditions of underground mines’ infrastructure is difficult to overestimate, but a lot of work must be still done to utilise the possibilities, which the newest technological advancements give us. In the AMICOS project, we create a fertile ground for the introduction of autonomous UAVs and UGVs in the raw materials sector to be used in smart mapping and inspection missions in the underground environment. The use-cases presented in the movie, are:
The 30th edition of the School of Underground Exploitation (Szkoła Eksploatacji Podziemnej) conference took place in Krakow from 27 to 29 September. DMC team joined other scientists, policy-makers, representatives of mining companies, and technology providers from Poland and abroad to present the effects of the most recent work performed in the scope of EIT Raw Materials projects. The main theme of the event was “Transformation of hard coal mining”, and the catchword “Mining will always be … but differently” could be repeatedly heard during the individual session panels, nonetheless the multitude of sessions’ topics ranged from the education of future raw materials industry workforce to IT solutions enhancing production processes in mining.
As a new week began we had a guest from the ESKA Radio and a Lower-Silesian newspaper – Gazeta Piastowska, who came to ask some questions about the OPMO project. Our leader – Professor Radosław Zimroz explained how mathematicians and mining engineers work together to develop solutions making ore processing more and more efficient.
Dr. Pavlo Krot and Dr. Jacek Wodecki presented their research achievements at the MOSCOSSE’2021 workshop organized by The Laboratory of Mechanics, Modelling and Production (LA2MP) from the University of Sfax, Tunisia, and the Department of Mechanical and Aeronautical Engineering, Centre of Asset Integrity Management (C-AIM) from University of Pretoria, South Africa.
It was a pleasure to see our colleagues presenting case studies and findings in such fields of complex systems studies related to three of our projects (MaMMa, OPMO, and SafeMe4Mine) as:
We have all broadened our horizons and learned some new valuable things thanks to the exchange of knowledge with a very interdisciplinary and skilled group of workshop participants. Thank you!
Why not take advantage of the beautiful snowy weather that visited Wrocław?
Today two of our robots have been tested in conditions, that they have never experienced before. Our wheeled robot performed probably its most unusual mission ever – to carry an operator on a sleigh ride.
We have identified some significant limitations and problems to solve in order to allow robots to perform their inspection missions in, for instance, open-pit mines wintertime. We checked how low temperature affects their performance, and, last but not least -enjoyed our work a lot!
We have also discovered that spiders feel a bit lost in the winter scenery…
