Abstract: Introduction. The paper analyzes the influence of natural and man-made factors on the state of ore-bearing rock masses during underground mining of solid minerals. It has been demonstrated that consideration of the rock mass geodynamics is an important factor in the efficient operation of mining companies, and that the stress level can be regulated during different stages of the deposit development. One of the priority methods to manage production of mineral resources is the concept of geodynamic zoning of the deposit during the mining phase with combined functions of the loading and bearing elements of the rock mass as part of the geomechanical system. The purpose of the article is to develop a concept of resource-saving geological management in underground mining of solid minerals. Methods. The methods applied included generalization and analysis of research, experiments, modeling and engineering forecasting using the methods of mathematical statistics and information technology. Results. The analysis of criteria are provided for the preservation of the land topography during mining operations, as a guarantee of safe development of the deposit. It is shown that mining operations are located within the field of stresses and displacements caused by the combined effects of natural and man-made factors. It is determined that the rocks form stable systems made of naturally wedging structural units during the mining process, and that such systems can be created by engineering solutions, e.g. creating man-made rock masses, dividing the ore field into the safe areas, etc. Types have been identified of the methods to calculate stable spans of roof exposures in the mining workings during the time when stowing of the mined-out space is completed. It is noted that the strength of the tailings resulted from block underground ore leaching can reach up to 1 MPa due to presence of natural binders, and these tailings can be used in rock pressure management. The proposed criterion for the reliability of the mined-out space stowing technologies is controlled by the ratio of the extracted ore volumes and consolidating stowing. It is established that transformation of the dynamic phenomena within the rock mass into the static ones is carried out by unloading the rock mass below the critical stresses. Conclusions. Accounting of the geomechanical state of the earth's crust is involved in solving the mining tasks, including the safety of mining operations, the quality of the mined ore and other economic indicators.
