Abstract. The paper presents results of the research and solution of practical task of defining stress-strain state of the massif in conditions of the “Gigant-Glubokaya” underground mine at the PJSC “CGOK” with the help of special software. The research was conducted in the site of 2.1 km long along the strike and 900 m deep. All the calculations have been performed on the basis of Ansys 16.0. The simulation was made for two cases: empty dead stopes and stopes filled with consolidating fillers. It is defined that with empty stopes level of the daylight surface subsidence is rather significant, and it is unacceptable for residential development and urban infrastructure. However, the curvature radius of such displacements develops quite small movements not critical for territories with dacha (country house) or garage communities. Use of consolidating filler in the backfilling dead stopes was proved for decreasing stress in the massif and preserving the surface ground. The simulation results possess high convergence to instrumental observation data. This allows to conclude that the developed model is adequate to the mining and geological conditions of Kryvyi Rih basin and can be used for simulating stress-strain state of the massif and forecasting further development of processes in rocks during underground mining operations.
Keywords: stress-strain state, massif, strain, stress.
