ABSTRACT: In the paper the authors present experience gathered during exploitation of the thick and steeply dipping 510 coal seam by means of a shrinkage method using exploitation galleries for seam development at “Kazimierz-Juliusz” coal mine (KWK “Kazimierz-Juliusz” Sp. z o.o.) in Sosnowiec. This particular method of mining thick and steep-dipping seams was proposed and developed by a team of engineers from the Mine and scientists from AGH-University of Science and Technology in Krakow. The method was employed to mine this part of the 510 seam located within the boundaries of “Kazimierz-Juliusz” mine, whose thickness exceeded 20 metres and which occurred at a dip of 35 to 45 degrees. The notes presented here refer to this experience. The paper covers the topics of influence of the described mining system on neighbouring excavations as well as on the rock-mass in the area of exploitation, taking into account mining hazards involved. It presents the obtained up-to-date technical and economic parameters characterising the system.
