As part of the Bureau of Mines effort to establish a comprehensive subsidence data base for subsidence technology development, subsidence and related data are being compiled for various mining, geological, and environmental situations. This report presents data for a longwall mining operation in the northern Appalachian coal region. Vertical displacement and relative face positions are tabulated for 160 subsidence monuments. Measurements were taken 32 times during the 2 years it took to mine the 2 panels. Brief physiographic and geological descriptions of the mining site are presented along with a general account of the mining and subsidence monitoring methods.
