The inclusion of a new term "planned subsidence" in the Surface Mining and Reclamation Act of 1977 has lead the U.S. coal mining industry into a new aspect of engineering: subsidence planning. Subsidence planning has necessitated the integration of geotechnical, civil, and mining engineering disciplines. Although much of the foundation and application work has been completed, subsidence planning is still a developing area. This paper discusses the application of subsidence planning in several brief case studies (a high voltage transmission tower, a sewage treatment plant, and a slurry impoundment), emphasizing the risk assessment aspects necessary to account for some of the uncertainties that may exist.
