Abstract
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 displacements and relative face positions are tabulated for 110 subsidence monuments. Measurements were taken 12 times during the 8 months it took to mine the panel. Brief physiographic and geological descriptions of the mining site are presented along with a general account of the mining and subsidence monitoring methods.
