Mine subsidence is the movement of the ground that can occur after underground coal mining. After coal is extracted from beneath the ground, the land above can sink and fill the hollow mine workings. This can cause tilts and strains on the ground surface.
To ensure community safety, it is important people living in active or non-active mining areas are aware of what mine subsidence is, the signs that mine subsidence may have occurred and to immediately report any subsidence safety issues.
