11/1/2008 - Peer reviewed journal articlesThis paper provides an assessment of the performance of limestone pillars as observed at 98 different locations in 34 mines in the Eastern and Midwestern regions of the United States.
-
6/1/2008 - Peer reviewed journal articlesThis paper describes a modeling approach that can be used as a tool to evaluate potential roof failure and optimize the stability of room and pillar layouts.
-
1/1/2007 - Peer reviewed journal articlesSome of the issues affecting pillar strength at low width-to-height ratios in hard, brittle rock are investigated. The results showed that the strength of slender pillars is more variable than that of wider pillars.
