The objective of this study was to examine the apparent influence of soil and near surface rock strata on the severity of damage experienced by surface structures subjected to mine subsidence. The report discusses (1) modes of ground movement that might complicate or be confused with mine subsidence, (2) prevailing concepts concerning mine subsidence in the northern Appalachian coalfield and Illinois Basin, (3) apparent influences of soil and near surface rock strata on the character of subsidence-related ground movements, (4) classifications and criteria for characterizing damage due to ground movements, and (5) types of subsidence damage experienced by homes above active mines in western Pennsylvania. A damage classification system that incorporates a severity index to characterize damage to homes with basements above active mines is presented. Also, a series of case histories illustrate subsidence damage to structures above active and abandoned mines.
