Soma has mine subsidence problems associated with production. Therefore, property and infrastructure damage will be related with coal-mine subsidence in Soma. In this study, depending on the underground coal mine production method, damage of subsidence on energy line was determined in Soma-Turkey coalfield. Subsidence may still occur in these areas. Therefore, determining subsidence is very important. Finite element methods (FEM) and field measurements were used for determining the parameters of mechanisms. The software, Phase2, used for the numerical modeling was developed by Rockscience Inc. The results obtained from modeling have been found to be compatible with previous studies and hale been compared with actual field observation.

W Somie wystąpiły szkody górnicze związane z osiadaniem gruntu. Dlatego też uszkodzenia własności i infrastruktury badane będą w związku z osiadaniem gruntu. W artykule określono wielkość uszkodzeń linii energetycznej w zagłębiu węglowym Soma (Turcja) w zależności od zastosowanej metody wybierania. Ponieważ nadal ma miejsce osiadanie gruntu, ważne jest określenie jego zasięgu. Wykorzystano metody elementów skończonych raz pomiary terenowe dla określenia mechanizmu osiadania. Oprogramowanie Phase2, wykorzystywane w modelowaniu numerycznym, opracowane zostało przez firmę Rockscience Inc. Następnie wyniki modelowania, zgodne z wynikami wcześniejszych badań, porównane zostały z wynikami pomiarów w terenie.
