Abstract: The relevance of research into seismodynamic processes of a natural and man-made nature is presented. Dynamic and gas-dynamic manifestations of rock pressure during the period of longwall mining along seam 16 of the «Yubileynaya» mine are presented. It is shown that the information acquired in practice about the intensity of rock pressure in hazardous areas is not recorded in separate documents and is not analyzed by scientific specialists, but exists only in the form of separate experience of mine specialists. The features of mining operations in zones of increased seismic activity during operational work at the «Yubileynaya» coal mine are outlined with the determination of increased rock mass stresses based on the geodynamic zoning of the deposit. An analysis of methods for assessing the intensity of the predicted impact of geodynamic hazards was carried out. It has been proven that in zones of geological disturbances, seismic potential is realized in the form of rock bursts or sudden rock outbursts, complicating mining operations, while the mining operations themselves have a provoking effect on the stressed state of the massif. The risks associated with carrying out work in areas where deep faults intersect are considered. The degree of influence of geodynamic activity within the mine field has been determined. It has been determined that the rational and most complete development of reserves, providing the safe conduct of preparatory and clearing work, must take into account the mutual influence of adjacent excavation blocks when designing and orienting the excavation field. A scale of risk distribution across zones of influence of geological faults and disturbances on mining operations within the «Yubileynaya» mine is proposed for consideration. The predominant influence of natural stresses on mining processes has been noted. Recommendations and technical measures to prevent the negative impact of seismic activity within the Western block of the «Yubileynaya» mine are presented.
