Abstract: The article discusses the urgent problem of forecasting the magnitude of rock pressure based on the identified patterns of changes in the state of the rock mass during man-made intervention in the process of underground mining. The research methodology combines methods for establishing correlations between the properties and disturbance of rocks, determining criteria for assessing the strength of rock masses and identifying the critical stress values. The problem of refining Sadon deposits while ensuring the stability of rocks and the safety of workers is formulated. A reference is given on the geological structure of the deposits with details of the conditions of the promising Jimidon deposit. The results of measuring rock fracturing, elastic wave velocity in rocks and rock properties are presented. The natural interdependence of the compressive strength and wave propagation velocity has been established, as well as the degree of elastic deformations and porosity. Information is provided on the strength and the structural degradation of the most representative rocks of the field. It is confirmed that the adhesion of rocks increases according to the parabolic law from the minimum value at the hole boundaries to the maximum value in the undisturbed rock mass, on the basis of which the stability of rock outcrops is assessed. A typification of rocks with differentiation by category is proposed and approximate values of stresses and displacements of particles are indicated. A dependence graph of the zone of inelastic deformations on the depth of the excavation is constructed differentially for rocks of different stability. It is shown that the development of new technologies with leaching needs a geo-mechanical justification. It is noted that the results of the study can be applied in underground mining of mineral deposits. It is concluded that resuming or activation of mining operations is possible with the modernization of the theory and practice of the rock mass management.
