• Description:
  "Subsidence over a series of longwall panels under-mining sloping terrain in southwestern Pennsylvania was monitored to verify the Bureau of Mines subsidence prediction model for the northern Appalachian coal region. Comparison of the field data to model output shows close agreement. Vertical movements over each panel ceased with the mining of the adjacent panel. Horizontal movements were significantly affected by topographic slope. The distributions of horizontal strains over each panel were similar, with a zone of compression occurring over the center of each panel. The zones of compression were flanked by zones of tension toward the rib. The magnitudes of the tensions were affected by the slope. The strains developed at the completion of each panel were not significantly altered by the mining of subsequent panels." - NIOSHTIC-2
