2/1/2007 - Peer reviewed journal articlesA study of ground behavior, reinforcement performance and stress redistribution looked at a longwall tailgate under severe horizontal stress. Comparison to field results showed that a FLAC-2D model captured the significant roof and support behavior.
-
2/1/2005 - Conference papersHighwall stability remains a major concern during highwall mining. Geologic structure (hillseams) and pillar stability are the two major factors affecting highwall stability.
-
8/1/2004 - Conference papersThis article discusses highwall stability, reasons for early pull out of highwall miner holes, and geotechnical engineering and planning factors, as well as operating practices to improve highwall stability and minimize the risk of a trapped miner.
-
6/1/2004 - Conference papersThe point estimation method for the probability of sliding is efficient and expedites slope stability simulation routines in NIOSH software to stochastically describe rock slope behavior and assist engineers in catch bench design for large slopes.
-
2/1/2004 - Conference papersThe primary goal of this project was to obtain detailed data on the interaction between the mine roof and the support elements for use in modeling studies.
-
10/1/2003 - Information CircularsThis report describes the geologic origin, association, and potential danger from the most common hazards. Discussions of weak rock include drawrock, rider coals, head coal, stackrock, and stream valley effects.
-
8/1/2001 - Conference papersThis paper discusses misconceptions about how roof supports perform and factors that impact their performance. The paper is limited to a discussion of secondary roof support systems and powered roof supports such as longwall shields.
-
2/1/2001 - Conference papersThree 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.
-
8/1/2000 - Conference papersThe 1990s saw an unprecedented increase in technologies for more effective, easier to install roof support in underground mines. To facilitate application and improve mine safety, NIOSH developed the Support Technology Optimization Program (STOP).
-
8/1/2000 - Conference papersTo determine causes of slope failure and highwall/spoilbank failure, this study reviews accident statistics, surface mining laws, the relevant literature, and observations from mine visits. The study emphasizes surface mines in WV, OH, and PA.
