Change in stress–strain behavior of coal-rock mass during coal mining

The research focuses on the construction and description of an assessment algorithm of change in the stress–strain behavior of rock mass during mining of coal seam in Kirov mine. Within the research, the algorithm was constructed and implemented in the form of a 3D model of coal seams Boldyrev and Polenov, roof and floor rocks from ground surface down to a depth of 1500 m, positional relationship of geological bodies and fault zones. To this effect, the spline approximation of the curved boundaries and surfaces was used. The model was adapted to the specific conditions of Kirov mine by calibration using the field measurements of subsidence of the check points on ground surface during mining in longwalls 2458 and 2459. The stepwise approximation produced the ‘effective’ values of deformation characteristics which ensured an admissible agreement between the measured and calculated subsidence of ground surface.

Keywords: carboniferous array, state of the array, stress-strain state, geomechanical model, modeling, geomechanical research.
