In the eastern US, thousands of acres of land in urban areas are threatened by subsidence as a result of coal mining. Roof collapse, crushing of pillars, or punching of pillars into the floor are now resulting in sinkhole or trough subsidence tens, or even hundreds, of years after mining. In areas of active mining, where total extraction is practised, subsidence is essentially contemporaneous with mining. Ground deformations resulting from subsidence have often been assumed to cause damage to structures in terms of simple tension and compression transferred by friction and adhesion to the undersides of foundations. Differential settlement, intensified pressure on sub-grade walls and other modes of soil-structure interaction are of equal significance in the eastern United States.
