The study to determine the position of the powered roof support<br>was conducted in an active longwall. The research team made measurements of the geometric height of<br>the powered roof support structure located in the longwall complex. The main objective of this study<br>was to determine the position of the powered roof support in actual underground conditions. The<br>analysis of the results provided data on whether the assumed height of the longwall was maintained<br>during operation of the complex.</p&gt;}, number={2}, journal={Inżynieria Mineralna}, author={SZURGACZ , Dawid and ZHIRONKIN , Sergey and TRZOP , Konrad and VÖTH , Stefan and SOBIK , Leszek and CEHLÁR , Michal}, year={2021}, month={grudz.} }
