The objective of this study was to define the parameters that contribute to the development of subsidence from multiple-seam coal mining and evaluate subsidence estimation techniques using data from an existing site. An extensive literature search and review of precalculation methods available suggested that the stealth program, developed by Science Application, Inc., had considerable potential for predicting multiple-seam mining subsidence. Results of the search for documented case histories of subsidence from multiple- seam mining revealed that either the full extent of the subsidence is unknown or the contribution of one or both seams is not available.
