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.
-
10/1/2009 - Peer reviewed journal articlesInstruments remaining in a test section of a lead/zinc/copper room and pillar mine where pillar mining had taken place 14 years before were read to monitor long-term stability and quantify time dependent behavior in the mine roof and backfill.

9/1/2006 - Peer reviewed journal articlesUS coal mining organizations are losing the knowledge they need to be able to respond to emergencies. Knowledge management provides a useful perspective from which to view the problem. Knowledge can be managed by cultivating it through narratives.
-
4/1/1999 - Peer reviewed journal articlesThe Coal Mine Roof Rating (CMRR) has been widely accepted as a tool for geologic characterization and mine planning. The application of the CMRR to extended cuts (cuts greater that 6 m (20 ft) in length) is discussed.
-
1/1/2020 - Peer reviewed journal articlesA paper presenting a new equation for calculating accurate abutment angles for deeper mining cases. The new equation was tested using both ARMPS2010 and LaModel for the entire case history database of ARMPS2010.
-
5/1/2018 - Peer reviewed journal articlesA study exploring the geomechanics of bench room-and-pillar mining and the associated response of high pillar ribs at overburden depths greater than 300 m.
-
1/1/2018 - Peer reviewed journal articlesA paper addressing the geotechnical considerations for concurrent pillar recovery in two coal seams with 21 m of interburden under about 305 m of depth of cover.
-
1/1/2017 - Peer reviewed journal articlesA paper detailing observations made in four consecutive room and pillar retreat panels and the data collected from an instrumentation site during retreat mining.
-
3/1/2012 - Peer reviewed journal articlesIn this paper, the authors review existing proximity warning technologies, describe ongoing NIOSH research on an intelligent proximity warning system, and summarize current test results.
-
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.
