• Coal Mine Subsidence Prediction Using a Boundary-Element Program
  3/1/1999 - Conference papers
  This paper presents several case studies in which a mechanics-based boundary-element program is used to back-calculate the surface subsidence associated with various panels at several northern Appalachian coal mines.
• Subsidence Prediction Using a Laminated, Boundary-Element Program
  6/1/1998 - Conference papers
  Historically, the surface subsidence over underground coal mines has been predicted using empirical profile or influence functions which have little or no connection to the actual mechanics of the subsidence. This paper presents a case study where a me...
• Modeling the Effects of Longwall Mining on the Ground Water System
  1/1/1995 - Reports of Investigations
  A hydrologic-subsidence investigation was performed to evaluate the effects of longwall mining on the local groundwater regime through field monitoring and numerical modeling.
• Timing and Duration of Subsidence Due to Longwall Mining
  1/1/1995 - Reports of Investigations
  Subsidence data gathered by the U.S. Bureau of Mines over a series of longwall panels in the Pittsburgh Coalbed were studied to obtain insight as to the role of time in the subsidence process. These results were then compared to data from three other si...
