Abstract:

Purpose. To substantiate geomechanical principles for reducing stress concentration peaks during mining operations in gas-dynamic rock masses at great depths in coal mines.

Methodology. The methodology integrates theoretical, numerical, and experimental approaches. Computational modeling using the finite element method was performed to analyze the stress-strain state of the rock mass. Vertical and horizontal stresses, stress intensity, and their distribution isolines were evaluated. In parallel, acoustic emission measurements in the near-face zone were carried out to assess the degree of stress relief, with results compared against sections excavated using conventional technology. The synthesis of numerical and experimental data enabled the formulation of methodological principles for calculating the parameters of the proposed technology and assessing its resource-saving effect.

Findings. The study confirms that the application of a comprehensive stress-relief technology, combining pre-drilled boreholes with stress-relief slots, significantly enhances mine working stability in gas-dynamically active coal-bearing rock masses at great depths. Vertical rock pressure manifestations are reduced by 7.3 % and horizontal pressure by 10.2 %, leading to a decrease in cross-sectional area losses of up to 18.2 %. Acoustic emission measurements demonstrated weakening of the near-face rock mass, with a 7–28 % reduction in energy at 2.0–2.5 m from the excavation face and 32–58 % within 3.0–6.0 m. Energy consumption for rock fracturing decreased by 15–26 %, with an average of 19.5 %.

Originality. A geomechanical model was developed that, for the first time, accounts for the combined effect of boreholes and slots on the stability of mine workings. New correlations were established between stress redistribution and acoustic signal energy as indicators of stress relief in the near-face zone.

Practical value. A safe and resource-efficient method for constructing excavations in gas-dynamically active rock masses at great depths has been proposed, enabling a reduction in cross-sectional area loss by up to 20 %.
