MAQOLA ANNOTATSIYASI

: In the world, the modern development of the mining industry is directly related to the development of complex structural mineral deposits at great depths under conditions of geodynamic and geomechanical risk. Especially when mining mineral deposits underground at great depths, rock pressure is manifested in a dynamic form and there is a danger of rock bursts. The practice of mining in rock burst conditions and the fight against rock bursts have more than 100 years of history. However, many important issues are currently far from being resolved, which is due to the complex nature of the stress-strain state of the developed deposits of mineral deposits, the formation of which involves numerous natural and man-made factors that are difficult to take into account. In this regard, rock pressure management with the use of methods and tools for assessing and monitoring the geomechanical state of a rock mass, fully taking into account the features of geodynamics and mining conditions within specific ore fields, is an important scientific and technical task. The article presents the results of an assessment of ways to eliminate the negative consequences of geomechanical processes occurring in the rock mass of the Kochbulak and Kizilalmasai deposits based on geodynamic modeling of a natural stress field.
