Theoretical and experimental studies carried out by the scientists in the field of mining development as a science are summarized. It is noted that any science, including geotechnology, is not a constant, absolute, and static value. It is noticed that the scientific picture of mining as a science is created by combining disparate scientific concepts and principles into a single whole, generalizing previously obtained knowledge and giving a common vector of ideas about the patterns and properties of reality. The unifying vector of its development from simple extraction from the subsoil towards renewable resource technologies is analyzed. The conditions are revealed, the integral presence and inseparable connection of which predetermines the concept of the georesources integrated development. The concept of geotechnology is defined from the point of view of the environmental safety, as well as the patterns of its development and the consequences of the georesources for nature and society. Measures are indicated that can significantly increase the economic efficiency and environmental friendliness of mining operations and contribute to the introduction of the resource renewable technologies in the integrated development of georesources. Issues of the environmental safety of modern technologies for the georesources exploitation are considered. The tasks are set that are quired for the solution at introduction of the resource renewable technologies, which implementation will allow to provide the maximum ecological safety. The principle of environmental safety is determined, which must enter into the practice of deposit development with the integrated use of natural and technogenic georesources. It is proposed to evaluate the individual design solutions for the development of natural and technogenic deposits from the point of view of maximum environmental safety of the entire technological scheme of a mining enterprise.

The results of the scientific and research work devoted to modeling the stress-strain state of the mining system of an underground mine using the finite element method in the FLAC3D software are presented in the article. The possibility of using room-and-pillar mining with backfill with the abandonment of chain pillars is justified. The results are presented concerning the research results of the quantitative assessment of the mass using the von Mises equation and Norton' power law of creep to estimate the contour stress. It becomes possible to determine the sequence of mining of the deposit area and the stage-by-stage filling of the stopes at the stage of mining design due to the high accuracy of modeling the stress-strain state of the mass near mining operations using FLAC3D software. The proposed approach is possible when evaluating the geotechnical state of the rock mass when using the mining systems with various methods of support of the mined-out area: natural; artificial; with the collapse of ores and enclosing rocks, as well as when calculating the combined method of deposit development. A differentiated approach to assessing the state of the mass is possible considering difficult mining and geological conditions, conditions of increased rock pressure, abundant water influx, increased fracturing of rocks by introducing additional conditions into the model depending on its geotechnical state. Variant of the comprehensive exploitation of mineral resources was proposed considering the total value of natural and man-made geo-resources of the area being mined. The possibility of rational use of the mined-out space with the use of various positive qualities of geo-resources at their manmade transformation is also considered. An assessment of the mineral and raw materials potential of the mined area is given with a proposal for the prospects of increasing the integrated approach of excavation, increasing the life of the mining enterprise and the complexity of developing this area.
