The purpose of this study is to investigate cases of subsidence over the abandoned mined-out areas of the Pittsburgh coal identified from published and unpublished sources and to determine through a consideration of the geology, topography, climate, mining activity, and evidence at ground surface, what mechanisms control subsidence and under what circumstances it takes place. The report identifies 354 incidents of subsidence in the 8,000-mile Pittsburgh coal region. One is located in Maryland, one is located in west Virginia, and the remainder are located in Pennsylvania. Case histories of several incidents of subsidence above abandoned mines are presented.
