Abstract: The article discusses studies and monitoring of the geomechanical state of a rock mass using the case of the MaloTulukuyevskoye uranium deposit in the southeastern part of Transbaikalia in order to predict rock bursts and control dynamic manifestations of the rock pressure. The interaction of mining and natural processes in the region is considered as synergetic, while tectonic faults, seismic activity, and the influence of seasonal climatic changes make a significant contribution to the geodynamic situation. The Prognoz-ADS automated rock pressure monitoring system was implemented to monitor in-situ rock pressure, and the seismic and acoustic monitoring was organized to cover two key areas with higher activity. The system enables registration of microseismic events and their parameters such as the energy and coordinates, which contributes to an early detection of dynamic phenomena precursors and improve the safety of mining operations. As a result of the monitoring conducted from 2022 to 2024, 431 acoustic events were recorded, which made it possible to identify two zones of stronger seismic activities associated with the intersection of the active geological faults with the mine workings. These data confirm previous studies indicating a high risk of rock bursts in the bottom part of the deposit, especially in the areas with the depths of more than 500 m. The impact of external factors, such as seismic activity in the region and climate change, on the intensity of seismic events was also analyzed. The results showed that during the summer precipitation season, delays occur in the rock mass response to climatic impact, which requires further monitoring. Recommendations for improving the monitoring system are proposed, including optimizing the configuration of geophones to enhance the accuracy of event localization and increase the coverage of the control area. The article is an important contribution to studies and risk management of the rock bursts, as well as to development of the seismic and acoustic monitoring methods in the mining industry.
