• Multiple-Seam Mining Interactions: Case Histories from the Harris No. 1 Mine
  5/1/2007 - Conference papers, Information Circulars
  A detailed evaluation of the multiple-seam experiences at Harris No. 1 Mine was done as part of NIOSH's nationwide multiple-seam mining case history database.
• 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.
• Proceedings: New Technology for Ground Control in Multiple-seam Mining
  5/1/2007 - Information Circulars, NIOSH/USBM numbered publications
  Multiple-seam interactions are a major ground control hazard in many U.S. underground coal mines. NIOSH has been conducting research to develop better techniques for predicting the location and severity of multiple-seam interactions.
• Multiple-Seam Mining in the United States: Background
  5/1/2007 - Information Circulars
  For the past several years, NIOSH has been conducting research to develop better techniques for predicting the location and severity of multiple-seam interactions. This paper presents the background to that study.
