Abstract: The analysis of the geological conditions of gas-dynamic phenomena occurring as a phenomenon in the form of sudden outbursts of salt and gas from the face during development in seam AB showed that practically all cases of intense gas evolution during driving of preparatory headings in the minefield of BKPRU-2 mine are spatially located within the Zyryansky fault and its zone of influence. Therefore, the research subject in this article are thrust and displacement areas in the mine fields of the Berezniki potash mine 2 and 4 of PJSC Uralkali. The purpose of the study is to develop recommendations for the safe management of mining operations dangerous in gas dynamic phenomena in the thrust and displacement areas, taking into account the gas content and tectonic structure of the layers being developed in the mine fields of the BKPRU-2 and BKPRU-4 mines of PJSC Uralkali. In the process of performing research works, geological information was analyzed and generalized in the mine fields of the BKPRU-2 and BKPRU-4 mines, geological sections were digitized, detailed structural maps of the mine field were plotted along the AB seam, and the overthrust and displacement areas were identified. The experimental estimation of the gas content and gas dynamic characteristics of seam AB and enclosing rock in the overthrust and displacement areas the mine fields of the BKPRU-2 and BKPRU-4 mines is performed. The recommendations on the management of gas-dynamic processes in mining operations in overthrust and displacement areas in the mine fields of the BKPRU-2 and BKPRU-4 mines of PJSC Uralkali are developed.
