【 摘 要 】
The paper is a case-study of ground surface subsidence induced by a short-term mining exploitation of hard coal. Budryk-Knothe's prediction theory is commonly used in Poland as a technique for prediction of the subsidence-related deformation of ground surface. The presented issue is related to assumptions about the value of the theory parameters in short-term forecasts on the impact of mining on the surface. Incorrectly selected values can significantly influence the quality of deformation forecasts. The calculations presented in the article were made for the area where the exploitation of one coal seam lasted for few years. At the same time, deformations of the surface were observed by means of geodetic measurements. Parametric calculations were made for the increasing range of mining operations.
