The article describes the modification of the technology intended for the disposal of coal dust at the Coal Sorting Plant facility in the Ledvice Coal Processing Plant (úUL) operating section of Severočeské doly a.s., caused by the need to respond to the change in the emission limit of Decree No. 415/2012 Coll. This involves replacing the existing dedusting equipment with a completely new one. Together with the newly designed filtration equipment, it was necessary to design a transport and mixing technology. This is used for the transport and subsequent disposal of the extracted coal dust. This dust is then returned in its changed form to the processing...

Aerial photogrammetry using UAVs, or rather the use of POINT CLOUDS, has been used in Severočeské doly a.s., Chomutov since 2021. The main use of this method is the update of mining survey documentation. New mapping methods can ensure better up-to-date documentation due to their operability. They enable mapping of complex geological areas, unstable slip areas or inaccessible dangerous places. This can positively affect risk prevention and increase work safety. Testing of the possibilities of supplementing the DRONE-CLOUD method with mobile ground scanning and "CLOUD TO CLOUD" registration was carried out at a time when UAVs cannot be used due to the weather.
