First week of field work at the Urgeiriça mine, Portugal

The UNEXMIN team is currently testing its innovative exploration solution in Portugal, at the closed and flooded underground Urgeiriça mine. The Urgeiriça field trials are divided in two sets of testing, with a period of laboratory work in between at INESC TEC. The first part has just ended and the first results are coming in:

  • 6th of March (Wednesday): The UNEXMIN team tested and packed the UX-1a robot and the needed equipment for the Urgeirica trials and travelled to the test site from Porto.
  • 7th of March (Thursday): The setup of the control room, launch site and the necessary communications went quickly as the Urgeiriça mine site had the appropriate infrastructures already in place. The first dive of the UX-1a robot was done on the afternoon of this same day, right after the team had received the necessary safety instructions from the Health and Safety body. The water table was ca. 7 m below the surface level in the shaft where the robot dived.
  • 9th of March (Saturday): The robot went down to 54m water depth (2nd level, 60m below surface level).
  • 11th (Monday) to 14th of March (Thursday): The UX-1a robot explored the shaft down to 104m water depth (4th level, 110 m bsl.). The entrances of the first four levels were mapped (1st level is at 30 m, 2nd at60 m, 3rd at 85 m and the 4th at 110m, below sea level).
    • The entrance chamber of the 1st level was partially collapsed, with lots of rocks, wood logs and metal pipes, so only a few metres were investigated not to risk the robot. The 2nd level is collapsed after few metres so it could not be searched. The 3rd level was in good condition, so this level was used in multiple test dives to test and develop the instruments. The visibility of the water in the mine was very good, and even with the sediment disturbed by the robot it sank quickly as it was in the sand-coarse size fraction.  The whole surface of the shaft was covered with wood, except the horizontal levels. The granite wall with black veins at the entrance of the 3rd level was recorded by the multispectral camera also. The γ-ray counter of the UX-1b was separately tested down to the 2nd level, lowered down in a cable parallel to another developed underwater γ-ray counter for cross validation.
  • 15th of March (Friday): The last dive was performed in the afternoon. After that, the control room and the site were partially disassembled until the second part of the field trials, from 1st of April onwards. The UNEXMIN team travelled back to Porto to INESC TEC’s laboratory and packed out the field equipment to continue testing and instrument calibration within the testing pool.

The first part of the Urgeiriça field trials went as expected: the UX-1a robot was further tested; instruments were working correctly; the robot as a whole performed its functions and managed to explore, map and gather information on some of the flooded areas of the Urgeiriça mine. These data will help the team to develop 3D maps and other visualisation tools of interest.

Now it is time for the team to proceed with the development of the UX-1b robot. This second robot, that will carry some other scientific equiment than its counterpart UX-1a, will be tested on the field during the second phase of the Urgeiriça field trials. It will collect some different data that will complement data gathered by UX-1a.

Back to the lab and then to the field again!

UNEXMIN next stop: Urgeiriça mine, Portugal

The UNEXMIN technical teams are on their way to Portugal in preparation of the third set of field trials linked to the project. This is set to happen between the months of March and April in the Urgeiriça uranium mine, Portugal. The novelty of this trial will be the presence of two UX-1 robots to explore and map the flooded part of the mine.

After the first two UNEXMIN field trials, at the Kaatiala mine and at the Idrija mine, it is once again time for the robotic and instrumentation developers to go to the field for one more trial. The third elected place to explore is a closed flooded mine in the centre of Portugal, the Urgeiriça uranium mine, once a very important source of radium and uranium. Here, the team will aim at exploring and mapping the three main shafts and tunnels, representing a more difficult environment to navigate and map when compared to its test site predecessors. Difficulty in operations will be characterised by the presence of two UX-1 robots operating within the waters of the mine: UX-1a and UX-1b.

The next robot UX-1b – from a final platform of 3 working prototypes – is currently being assembled and pre-tested in Porto at INESC TEC’s testing pool. Having two robots within the exploration and mapping platform gives security of operations, while at the same time, distributing the scientific payload through the surveyors, which translates into reduced size, weight and power demands of the individual UX-1 robots: one of the major benefits (and demands!) of the UNEXMIN robotic platform.

UNEXMIN at PDAC 2019!

Once again, and following the example of last year, the UNEXMIN project is invited to be featured in a exclusive European Union booth specially dedicated to showcasing some of the European Horizon 2020 projects focussed on exploration and mining. The PDAC conference is held in Toronto, Canada, and this year will be held between the 3th and 6th of March.

UNEXMIN is currently developing and testing a multi-robotic platform to do autonomous exploration and mapping of flooded mines that aims at fostering cost effective exploration from environments that might still have valuable mineral resources.

Besides the opportunity given to be showcased at the European booth with a presentation and movies about the project, two members of the UNEXMIN project, RCI (through GEOREKA Software) and EDM, will also be present at the Prospectors & Developers Association of Canada – PDAC, extending the UNEXMIN project scope on the event.

The UNEXMIN project was present at the EU Industry Days 2019!

The UNEXMIN project was one of the 28 projects that were invited to be present at the EU Industry Days 2019, in Brussels. This unique event aimed at bringing together personalities from the most diverse sectors of industry within the EU and to showcase projects that are having impact on the EU’s industry panorama.

During the 5 and 6 of February the UNEXMIN consortium was invited to showcase its results in the event “EU Industry Days 2019” in Brussels. The project had the opportunity to have a unique stand from where three persons and one robot provided information to the participants about UNEXMIN and its development. The UX-1 robot, shipped from Porto on the sole purpose of this occasion was the star, not only of the UNEXMIN stand, but also of the exhibition. A blinking robot – its lasers and many cameras – makes wonders.

Overall, the UNEXMIN stand received a lot of interest from the passersby. In total, around 60 persons over the course of the two days dropped by the stand to discuss the robot and the technology attached to it. People were interested in learning more about the different techniques employed and the many uses that the innovative UNEXMIN solution can have in different sectors. From energy, to mining, to fishing, to underwater caving exploration, the UNEXMIN solution has aroused the interest of the crowd. Some people even approached the project team with a commercial interest – it is always great to see that the technology interests the stakeholders.

The UNEXMIN consortium would like to thank EASME for inviting the project to be present at such an important event. The consortium also thanks all the interested people that went to the stand to learn more about the UX-1 robot and the project itself – after all this technology is made for you.
