The analysis and evaluation of method to increase mine stability in swelling rocks shows that each method has a certain field of rational use and the effectiveness of any method or action depends on how its mechanism corresponds to the real nature of the process. Based on the extensive field studies in the mines of DTEK Pavlogradugol company, a geomechanical model of floor heaving in permanent mine workings has been developed. This model enables design and installation of combined support at the reduced capital expenditure and maintenance costs. To this effect, the influence of the longwall face advance on deformation processes in the face-adjacent rock mass is analyzed. The article presents the analytical results on the change in geomechanical condition of adjacent rock mass under the longwall face advance. Three characteristic geomechanical zones are detected in the face-adjacent rock mass: elasticity, plasticity and elastoplastic instability.
