Abstract: The relevance of the research is due to the increasing risks of geodynamic phenomena during the development of deposits at great depths. Micro-impacts initiated by production processes lead to catastrophic consequences, disrupting the stability of underground workings. Classical models do not always adequately describe the complex structure of rock mass disturbance, which requires the use of new approaches. The aim of the work is to diagnose the nature of rock mass disturbance after a microburst at the Tashtagol field and to interpret the data obtained. The tasks included assessing the effectiveness of relief drilling and visual inspection for mapping the zones of unloading and compaction. The research methods included in-kind observations after the microburst: drilling relief wells and their subsequent visual downhole inspection using special diagnostic equipment. The results showed that the rock mass disturbance is not continuous, but has a clearly defined zonal nature. The well sections revealed alternating intervals of heavily and extremely fractured rock (disintegration zones) with areas of relatively intact rock mass (compaction zones). This picture corresponds to the theoretical model of concentric zones of unloading and compaction formed due to the wave nature of energy redistribution after a microburst. The scope of application of the results covers the mining industry and underground construction. The results allow us to improve the methods for diagnosing the state of the massif, predict the development of rock pressure and develop effective measures to ensure the stability of workings at deep horizons. The data obtained confirm the manifestation of the zonal disintegration effect during a microblow. Visual inspection of relief holes is an effective method for mapping relief zones. Understanding the zonal structure is critical for making correct decisions on supporting workings and managing geomechanical risks. The study is of interest to specialists in the field of geomechanics, mine geology and mining safety, offering a comprehensive approach from recording the consequences to their practical application.
