The article presents the stages of numerical modeling of the stress-strain and strength state of a rock mass in the area of a ventilation drift during the mining of flat seams. The problem is solved by the finite element method, taking into account the physical and mechanical properties of coal, host rocks of the roof and soil of the seam and their changes over time of mining. The technique also takes into account the influence of adjacent waste lava. To assess the strength state of the host rocks, the Mohr criterion was used, and to assess the strength state of the coal seam, the criterion of rock strength under volumetric compression was used. The dependences of changes in the values of deformation characteristics of rocks over time were specified by rock creep equations, which made it possible to use the variable modulus method. An example is given of calculating the distribution of the stress-strain state of a rock mass, the convergence of the roof and soil, and soil heaving along the length of a ventilation road. A significant influence of the creep of the immediate soil on the amount of heaving of the roadway soil is shown.
