Systematization of ore deposits is carried out according to geomechanical conditions on the basis of tectonic features. In total, more than 120 underground mines have been analyzed. Four models of the geo-environment are distinguished. They make it possible to differentially describe the nature of the change in the stress state with increasing depth. The efficiency and reliability of the use of typical geomechanical conditions of rock massifs for determining the field of application of geotechnologies is shown. Correlation links between geomechanical models of the geo-environment and development systems of ore deposits are established, taking into account the maximum depth of their development as a criterial condition for the development of the rating classification of geotechnologies. The proposed geomechanical models of the geo-environment and their corresponding development systems greatly expand the possibilities for assessing the mining situation in the ore fields and contribute to a more correct choice of the method for mining of raw materials. The systematization of rock massifs makes it possible to classify existing and explored deposits as a type and characteristics of tectonic structures to a certain class of geomechanical working conditions, taking into account the depth and, based on the initial data obtained, to predict the magnitude of stresses at the design and construction stage, to substantiate development systems and their parameters.
