Evaluation of subsidence due to underground coal mining

This paper presents a case study dealing with variations on the ground surface due to the underground mining activities in the Ostrava–Karvina Coal District (Czech Republic) over the last 25 years. During this period, some of the areas have experienced settlements of up to 11 m. Seven settlement intervals were used to indie the varying degrees of subsidence over time.
