    The paper presents the basic information about mining seismology, induced seismic activity in the region of KWK „Bobrek-Centrum” and geomechanics. Then, the author, on the basis of real data from the above mentioned mine, has developed a numerical models for static and dynamic analysis around the mining excavation, in the wall 3, coal seam 503 in KWK „Bobrek-Centrum”. In the case of static analysis, the impact of the mesh discretization density on the accuracy of distributions of stresses, strains and displacements in the numerical model was discussed. In dynamic analysis, by introducing additional external load (source of tremor) the effect of various parameters on the virtual seismometer record and the stress-deformation distribution was considered. The calculation has been performed in two–dimensional finite difference numerical modelling using software FLAC 7.0 (Itasca).
