Analysis on Ground Subsidence in Underground Mining

open access: yesAdvanced Materials Research, 2011
Analysis on the characters of ground subsidence of Yangjiaping mining area, with same excavation depth and recovery coefficient, the numerical simulations to nonlinear large deformation using finite-difference method(FLAC) are achieved on the different strip extraction schemes that adopted different mining and reservation width.

Problems of Ground Subsidence

Journal AWWA, 1955
usually been academic, principally to further his knowledge of the processes of formation and change of the earth's surface or to furnish an explanation of geologic observations. The failure of roof supports in mining operations conducted relatively close to the surface of the ground is one of the commonest causes of subsidence.

Subsidence and ground movements in chalk

Bulletin of the International Association of Engineering Geology, 1992
Subsidences which occur within, or near, the outcrop of the Chalk are due to the collapse either of solution features or of old mine workings. However, only the latter are considered here. Mine workings in the Chalk extend back into the distant past, the most ancient workings being those which Stone Age man excavated in his quest for flint.

Effects of Ground Subsidence on a House

Journal of Performance of Constructed Facilities, 1996
A one-story ranch house was monitored as it underwent static ground subsidence from longwall coal mining. The unreinforced crawl space foundation failed early in the subsidence event. The foundation was not flexible enough to conform to the ground movements, and not stiff and strong enough to ride out the movements.

Geophysical Surveys Across A Ground Subsidence Feature

13th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2000
In many parts of Southern England the Cretaceous chalk formation exhibits solution features which eventually lead to collapse and void formation. During early formation it is difficult to decide when small subsidence features are due to either man-made industrial/archaeological features or due to water ingress.
