Effect of geological and technological parameters on the convergence in a stope

Purpose. To study regularities in changes convergence of wall rocks along a setting line the powered props depending upon sandstone availability within roof, mining depth, as well its position relative to coal seam length extraction column based on results numerical experiments and forecast probable zones rigid settlement support units according longwall at any moment stope arrangement pillar accordance with geological technological parameters. Methodology. The paper represents 3D computer modelling incremental advance layered transverse isotopic rock mass while applying Solid Works Simulation 2019 software. Findings. research results, concerning nature distribution value stope, are given. were obtained using area initial caving main roof. Originality. In context Western Donbas mines, have been determined certain such system parameters as: 5 30 m thickness both immediate distance nonavailability roof; 215, 260 305 length; 150, 300 450 zone roof (1545 m) 10 increment distancing from an installation chamber 1050 distances. Practical value. identified make it possible location irrespective depth. abovementioned helps optimize for conditions mines if required.
