Description	If coal seams are mined by longwall mining, the original stress balance in the rock mass is changed. The stress increases around the mined-out area.As a result, increased stress causes compression around the excavation. The compression around the excavation is shown by exact measurable subsidence. The impact of mining can be theoretically determined by a limiting impact angle. The paper deals with the assessment of mining in the ninth and seventh blocks at Karvina Mine Lazy Plant and its influence on the surface. The process of failure of the mining seam’s rigid roof in both areas will be explained. On the basis of spatio-temporal relationships of real surface subsidence, mined longwalls, and geomechanical events, the character of overlying rock deformations can be evaluated. The character of rigid overlying strata will be evaluated by means of an inflexibility coefficient which has the advantage of including the main factors of influence: the thickness of the seam and the rigidity and compactness of the overlying strata.
