Engineering Physics Annotation << Back GEOMECHANICAL PRINCIPLES FOR THE FORMATION OF CONVERGENT MINING TECHNOLOGIES IN THE COMPLEX DEVELOPMENT OF SUBSURFACE RESOURCES YU.P. GALCHENKO On the basis of modern ideas about creating natural-like technologies, the processes of relaxation of excess stresses in a continuous medium with differentscale inhomogeneities are considered. the concept of constructing underground geotechnologies that create opportunities for permanent reproduction of stable dynamic structures in the lithosphere by controlling relaxation processes on the outer contour of the mined area of the subsoil is proposed. The implementation of this concept provides the prospect of mining the main part of the field’s reserves in conditions of high protection from the impact of most geofactors that occur in the equilibrium dynamic structures of the lithosphere during their technogenic changes. The proposed convergent Geotechnology is implemented in three stages: the separation of the mined section of the field into sections by dredging the contiguous reserves of each of them and the construction of the upper and side outlining artificial arrays; the division of the processed section into excavation blocks by constructing dividing artificial arrays; sequential or parallel development of reserves of excavation blocks using well-known high-performance geotechnologies. The choice of a solution in each real excavation block is regulated only by its local geological and mining characteristics. This allows you to use the most high-performance development systems. Economic efficiency is formed by a functionally justified combination of expensive and cheap geotechnologies in ratios determined by the actual development conditions.
