Abstract

In this study, the subsidence induced by sublevel caving production method applied in the Divriği Ekinbaşı underground mine was investigated and evaluated. In this context, on-site observations and measurements were made in the underground mine. Two point cloud datasets with an approximately seven-month time difference were analyzed, and surface collapses, cracks, and fractures were plotted on the map For each periods, the fracture initiation and subsidence angles of hangingwall and footwall sides were determined. As a result of the analysis of first and second data sets, subsidence angle of the hangingwall side remained the same as 50.40°, in the footwall side 72.84° and 53.44° respectively. The areas of fracture and subsidence regions increased by 4.67 ha and 7.67 ha, respectively, over a period of around seven months.
