The modern technocratic civilization has grown in the conditions of perpetual and irresolvable antagonistic contradiction between the biological essence of human beings as elements of the natural biota of the Earth and the abiological methods used to obtain the needed energy through extermination of the natural biota and its replacement by the anthropogenic biota of different functional purposes. The material and energy basis of the technosphere as an artificial living space for a human being is the substance produced as a result of irreversible destruction of the lithosphere. Permanently increasing difficulty and deeper level of mining make mining geomechanics the top-priority area of research. The stress–strain analysis is a requisite component of studies aimed at selecting a geotechnology and determining its parameters. This analysis evaluates mining-induced stresses. The values of such stresses are determined mainly at critical points of boundaries of mining-caused voids with a view to ensuring stability of exposed surfaces and pillars. The feasibility of ecological evaluation of mining-induced changes in the stress–strain behavior of the disturbed lithosphere using the appropriate procedure being developed can make it possible to rank geotechnologies using the related criteria. This allows taking one more step towards an engineering framework for the concept of sustainable nature and society activity in the course of the mineral sector development.
