The structure and bearing capacity of rock structures during underground mining

Abstract

Abstract The processes of controlling the ore-containing mass are refined and detailed, and the mechanism of interaction of stresses and deformations during underground mining of ore deposits is detailed. The properties of the massif and the role of faults and macrofractures in the development of deposits of complex structure are systematized. A methodology for studying stresses and deformations of rocks is given. Regularities of array maintenance at the interface site are established. Quantitative values of changes in physical and mechanical properties and stability of rocks in the interface zone are given. The array is differentiated by the magnitude of the acting stresses in various phases of the connection. The calculation of stresses for specific conditions with the determination of the reliability of the mining site was performed. Patterns of stress and strain changes over time are noted. An explanation of the phenomenon is given from the standpoint of the interaction of structural rock blocks in a discrete field of the array.
