Ground geodynamics control by regulating stress level

Abstract

Relevance. of the problem of integrated development and conservation of mineral resources is currently increasing by the need to improve technological processes based on new principles, which explains the need to develop new and modernize well-known methods for managing geodynamic phenomena in the massif. Aim. The object of the study is the rock complex structural deposits of the Sadon group of the Central Caucasus, the development of which increases stresses in ore-bearing massifs with a deterioration in the quality of subsoil use and makes it necessary to take into account technological impacts on the massif and measures of geomechanical monitoring of its condition. The aim of the study is to substantiate the feasibility and advisability of using the products of mining and concentration processing of ores and made on their basis after extracting from them the useful components of filling mixtures. Methods to achieve the research goal include systematization and ranking of geological, technological and economic data related to managing an array of data, development of optimality criteria and the formation of a concept for resource-saving technology for field development. Results. The concept of managing the geomechanics of ore-bearing arrays is detailed. The condition of the array strength at various stages of field development is given. A mathematical model of the interaction of variable factors is proposed. The mechanism of combining traditional technology with open mined space and a new technology with leaching of metals, both in blocks and in disintegrators, is formulated. The results of evaluating the possibility of using enrichment tailings as raw materials for the manufacture of hardening mixtures, obtained in the course of full-factor studies on state grant programs. Information is given on hydrochemical methods for producing metals in mines. The host rocks of the Sadon deposits are characterized by a redistribution of stresses, including in the geodynamic regime. Management of the geodynamics of ore-bearing rocks by regulating the magnitude of stresses in ore-bearing massifs requires the use of artificial arrays from the tailings of technological processes. It is shown that the mining of substandard ores and tailings from the enrichment of reserves involved in the production and the refinement of existing reserves using a combined scheme can be cost-effective.
