ABSTRACT
Abstract: Subsidence is a ground settlement that occurs on the surface after the underground mine excavation. The amount of the subsidence is particularly high for caving method applied in the thick coal seams. Subsidence amount depends on the thickness of bed, the slope of bed, and geological formations. This phenomenon also changed the width of the affected area. In particular, the control of the subsidence in the mines close to the residential area is very important. This section will be described in general and the effects of subsidence.
