Abstract

This article examines the main stages in the development of geomechanics, which has deep historical roots, leading back to the seminal works of Charles Augustin de Coulomb in 1773. Two and a half centuries later, this work gave rise to the scientific field of geomechanics of highly compressed rocks and massifs as a theory of critical states of the geoenvironment. Based on an analysis of historical documents and publications, the main stages in the development of geomechanics are identified. The results of the most recent period of development of geomechanics of high compression, following the introduction of the mesoscale of failure and structural levels of the geoenvironment, are briefly discussed. The results of experimental and analytical studies investigating the patterns of deformation and failure of the geoenvironment at the first (rock samples) and second (rock mass at the scale of mine workings) structural levels are considered. The reversible nature of linear deformations in the near-focal zone of macrofracture preparation of rock specimens during the pre-fracture stage of loading and the patterns of formation and development of contrasting mesofracture structures under these conditions are established. Zonal deformation of the rock mass around deep mine workings and the patterns of formation and development of the mesofracture zonal structure of failure for different rock mass types are also established. The experimental studies are accompanied by a description of the posed and solved problems of continuum mechanics with defects, leading to a non-Euclidean description of geoenvironment models. The results of theoretical and experimental studies are compared, demonstrating their complete qualitative and good quantitative agreement. In conclusion, the object, subject, principles, and methods of geomechanics of highly compressed rocks and massifs are considered, distinguishing this area of geomechanics as an independent scientific field as a unification of traditional geomechanics and physical mesomechanics.
