1/1/2011 - Peer reviewed journal articlesStone 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.
1/1/2011 - Peer reviewed journal articlesA field-expedient test method and portable on site test equipment have been developed to measure shotcrete strength in the first six hours after application.
7/1/2010 - Conference papersThe paper provides a basic set of input data and a modeling approach that can be used for numerical modeling investigations of various coal mine designs using the FLAC3D software package.
7/1/2010 - Conference papersIn 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.
