Knurów-Szczygłowice coal mine. The article concentrates on the support solutions applied in the conditions of the mine and the results in terms of stability and usefulness of the structures of the supports. An analysis of the load bearing capacity and technological conditions has been conducted for various flattened supports solutions, with special consideration given to the ŁPSp and ŁPrPJ support sets. Comparing these two, the ŁPSp exhibits a load bearing capacity that is 21% higher while using 31% less steel mass. The experiment results allowed to determine that the ŁPSpA and ŁPSp3R support types are an advantageous solutions in case of longwall set-up rooms.}, type={Artykuły / Articles}, title={Experience of using ŁPrP, ŁPKO, ŁPSp, ŁPSpA i ŁPSp3R flattened supports in the conditions of Knurów-Szczygłowice coal mine}, URL={http://www.czasopisma.pan.pl/Content/109769/PDF/g%C5%82uch-i-inni.pdf}, keywords={exploitation, supports, selection of supports for longwall’s set-up rooms}, }
