The chapter is based primarily on field surveys, done over a period of two years, supplemented by secondary data wherever available as well as reports of Pollution,workers, subsidence-proneSubsidence Modeling - Illinois Mining Institute,The coal company took measures to protect this home in advance of subsidence. Structures were raised from the foundations and kept level during subsidence. Foundations were restored and structures lowered onto them after damaging groundSurface Subsidence Due to Coal Mining in Illinois,Subsidence of the land surface has been associated with coal mining in Illinois since the early days of the industry. Investigations of subsidence damage began in Illinois more than 100 years ago. However, over the years there has been very little scientific or engineering documentation of subsidence movements in Illinois.
