This article addresses the problem of ensuring safe mining operations in gold-bearing ore deposits of the Angren mining administration under conditions of high stress and geodynamic instability of the rock mass. A technology based on the use of destressing boreholes is proposed and scientifically substantiated as an effective method for controlling geostatic and technogenic stresses.
It has been established that the application of destressing boreholes leads to stress redistribution within the rock mass, reduction of accumulated elastic energy, and formation of relaxation zones. The results of numerical modeling and field-scale experiments demonstrate a significant decrease in maximum stress values and an increase in geodynamic stability.
Furthermore, optimal parameters of boreholes (diameter, length, spacing) and their integration into the mining process are scientifically justified, enabling a reduction in rockburst hazards and an improvement in industrial safety. The obtained results are important for the active control of the stress-strain state of the rock mass and for ensuring safe and efficient mining operations.
