1/1/1998 - Peer reviewed journal articlesRoof and rib conditions were observed and assessed in 33 underground stone mines. It was found that selection of the mining horizon and mine layout decisions tremendously influence ground stability.
-
1/1/1992 - Information CircularsReviews the mechanics of rib failure and the relationship of coal mine geology and pillar constraint to rib instability. Strategies for choosing an effective method of rib support are considered and various rib support methods are discussed.
