Abstract
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 indicate the varying degrees of subsidence over time. Maps were prepared to show the spatial relationship of the subsidence and to assist in land use planning in this rapidly developing area.
Résumé
Cet article présente une étude de cas trait1497ant des modifications de la surface du sol en réponse à des exploitations souterraines de charbon dans la région d’Ostrava-Karvina (République tchèque) au cours des 25 dernières années. Pendant cette période, certaines zones ont connu une subsidence allant jusqu’à 11 m. Sept périodes de tassement ont été considérées afin de mettre en évidence l’évolution de ceux-ci au cours du temps. Des cartes ont été préparées pour montrer la répartition spatiale de la subsidence et pour orienter les projets d’aménagement dans cette région en développement.
