• Pillar Strength in Underground Stone Mines in the United States
  1/1/2011 - Peer reviewed journal articles
  Stone mines in the eastern and midwestern United States use the room-and-pillar method of mining to extract relatively flat-laying sedimentary formations. A survey of pillar performance was carried out to identify potential modes of instability.
• Roof Span Design for Underground Stone Mines
  7/1/2010 - Conference papers
  In this paper, the findings of a survey of roof span stability issues and design practices are presented, and the observed factors contributing to roof instability are discussed.
• Ground Control Design for Highwall Mining
  2/1/2005 - Conference papers
  Highwall stability remains a major concern during highwall mining. Geologic structure (hillseams) and pillar stability are the two major factors affecting highwall stability.
• Using the Coal Mine Roof Rating (CMRR) to Assess Roof Stability in U.S. Coal Mines
  8/1/2001 - Peer reviewed journal articles
  The CMRR quantifies defects in the rock mass and compiles a strength value used for engineering design. The CMRR has been applied to a number of ground stability problems. The CMRR procedure and some of these applications are described in this paper.
• Toward Pillar Design To Prevent Collapse of Room-and-Pillar Mines
  2/1/2001 - Conference papers
  Three alternative approaches to reduce the risk of catastrophic collapse are described: containment, prevention, and full-extraction. Without good data available on post-failure pillar behavior, containment and full-extraction are the safest.
