Underground mining operations could adversely affect the land surface and buildings on which it is located. Objects in the range of impact are affected by displacement and deformation. Mining Basin area is often highly industrialized and many important objects of the technical infrastructure is there. A considerable portion of these objects is characterized by elongated shapes. For this type of objects (pipelines, roads, railways, power lines) predictive analyzes of deformation are performed to assess the safety of their operation. For different linear objects, determined rates of deformation have different significance. The article presents various aspects of forecasting deformation for different types of linear objects. It presents the methodology of predicting deformation. It shortly characterizes a calculation model for deformation indexes used in Polish mining. The presented examples come from different extended engineering facilities, for which predicted indicators of deformation were set.
