Abstract

The concept of preservation of the earth's surface from destruction is realized in the present work through regulating the stresses by coordinating the processes of excavating the ore in time and space according to the criterion of stress minimization. Justification of technological solutions that ensure the preservation of the massif and the earth's surface above it due to the phenomenon of residual strength of disturbed rocks is the purpose of the article. The goal is achieved through analysis of mining practices, established behavior patterns of massifs with a discrete gravity-tectonic structural stress field and methods to ensure their stability by creating conditions for locking rocks within the dome of natural equilibrium. It is shown that the geomechanical balance of discrete rock structure is provided due to the residual bearing capacity of naturally and technologically depleted rocks. A solution is proposed for the prevention of critical stresses and their corresponding deformations by dividing the mine field into areas with a flat roofing, within which cost-minimized technologies can be applied. It is recommended to supplement the criterion of repayment optimality with the amount of compensation for damage to the environment. The typification of the mines depending on stability and disturbance of massifs is given. The condition of the solidity of the massif at various stages of existence is formulated - the condition of the geomechanical balance of the geomechanical system. The workings can be typified according to the stability, depending on the size of the structural blocks of rocks in the roof. The new classification of backfilling technologies with taking into account the phenomenon of rock blocks locking is proposed. Due to the residual bearing capacity of naturally and technologically depleted rocks, under underground mining of deposits there are rock constructions whose properties are corrected by dividing the mine field into geomechanically balanced sections with flat roofing
