The Bureau of Mines, in cooperation with the Illinois mine subsidence insurance fund, monitored the response of two foundations to ground movements induced by subsidence from high extraction mining in southern Illinois. The objectives of the monitoring program were to study the interaction between the ground surface and a foundation during a subsidence event and to determine the capability of the tiltmeter to detect and monitor subsidence movements. This paper describes the monitoring instrumentation and techniques as they relate to the mining and site conditions, and the capability of a tiltmeter to detect and follow the tilt of the foundations is also demonstrated.
