Ground Subsidence. Subsidence is the sinking or settling of the ground surface. It can occur by a number of processes. Ground subsidence may result from the settlement of native low density soils, or the caving in of natural or man-made underground voids. Subsidence may occur gradually over many years as sags or depressions form on the …

What is mine subsidence? Any Illinois homeowners might be surprised to learn that Illinois is one of the largest coal-producing states in the nation. Over 800,000 acres across the state have been undermined for coal. The underground mining of coal and other minerals creates voids which are subject to collapse.

If the collapse causes sinking of the ground surface, the settlement is called mine subsidence. There are two forms of mine subsidence which in Illinois are referred to as pit and sag. Pits are steep-sided holes that form over mines that are less than 180 feet deep. Most pits are less than 16 feet in diameter and 8 feet deep but range between 2 ...

Some of the language utilized was very broad and, arguably, would give the coal operator the right to mine and remove all of the coal under your land without leaving any support for your surface lands. Once the coal is removed, the land falls to fill the void. That is how subsidence damages occur. If a coal company is planning to mine under ...
