Аннотация: t. The article is devoted to detailing the principles of geological management based on the assessment and consideration of the geomechanical features of the behavior of rocks during the underground mining of ore deposits. Goals and objectives. The problem of mining of mineral raw materials is insufficient consideration of structurПоказать полностьюal factors when assigning parameters of ore extraction technology. The purpose of the article is to systematize the main provisions of environmental and resource-saving geological management in relation to underground mining of ore deposits. Methods – generalization and systematization of theory and practice, analysis of the results obtained and forecasting the possibility of their application in underground mining. The results of the study – summarized the principles of geological management based on the consideration of geomechanical features of rocks. Information is given on the theory of the processes of development of subsurface reserves, management of the state of arrays, and ensuring the stability of workings in discrete rocks. The condition of the strength of the wedging of structural blocks of rocks is formulated. The conditions for ensuring the geomechanical balance of the massif due to the separation into safe sections and methods for calculating stable spans of flat roof outcrops are given. A classification of methods for calculating roof outcrops from the conditions of the formation of the arch of natural rock equality is proposed. The classification of array management methods in the repayment stage has been clarified. Options for combining technologies with insulation, laying and leaching of ores are considered. A technology is recommended with the issuance of the richest ores on the surface and the processing of the rest in underground blocks, in which the movement of solutions is carried out and controlled with the prevention of contact of solutions with the biosphere. Conclusions – the problems of completeness of the development of mineral resources, waste-free extraction of valuable components, the creation of new environmental technologies are becoming a priority criterion for the effectiveness of mineral extraction technologies. Taking into account structural factors when assigning parameters of ore extraction technology contributes to the humanization of the processes of environmental and resource-saving geological management.
