• AMSS - Analysis of Multiple Seam Stability
  8/20/2013 - PC software
  A software program that helps to identify the location and likely severity of multiple seam interactions
• Multiple-Seam Mining in the United States: Design Based on Case Histories
  5/1/2007 - Information Circulars
  The goal of this study is to help identify the location and likely severity of multiple-seam interactions. Mine planners can use this information to adjust the ground support, pillar design, or mine layout to minimize the hazard.
• Multiple Seam Longwall Mining in the U.S. - Lessons for Ground Control
  2/1/2007 - Conference papers
  Relatively few longwall mines in the U.S. operate under multiple seam conditions where the two seams are less than 200 ft apart. This paper describes the experience of six that do and lessons learned.
• Analysis of Multiple Seam Stability
  1/1/2007 - Conference papers
  Analysis of Multiple Seam Stability (AMSS) is a computer program to help mine planners evaluate potential interactions and reduce the risk of ground failure. This paper details a NIOSH study of multiple seam interactions and the development of AMSS.
• Failure Mechanics of Multiple Seam Mining Interactions
  8/1/2005 - Conference papers
  This research seeks to provide design guidelines that enable mine planning engineers to assess the safety risk of an adverse multiple seam mining interaction based on mine geometry factors, mine layout factors, and site specific geologic conditions.
