摘要：

The creation of geomechanical balanced rock environments for underground mining of rock deposits is substantiated due to the phenomenon of self-hardening of natural and technologically destroyed rocks when exposed within acceptable limits. The direction of the solution of the problem of controlling the state of the array is indicated by preventing critical stresses and strains as a result of dividing the mine field into geomechanical stable sections with a flat roof. It is recommended to supplement the criterion of the optimality of the void repayment by the amount of compensation for damage to the environment. The condition for the strength of the array at various stages of the existence of the geomechanical system is formulated. A new classification of voiding technologies is proposed, taking into account the phenomenon of jamming of rock blocks.
