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.
-
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.
-
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.

6/1/2008 - Conference papersThis paper compares the transverse load capabilities of several block materials and wall dimensions commonly used in stopping constructions based upon simulated three-hinge, rigid-arch loading tests of half-wall constructions.
-
6/1/2008 - Conference papersThis work attempts to provide rock mechanic tools that will enable a mine operator to make economic decisions that will also ensure a safe working environment.
-
10/1/2006 - Conference papersHand scaling is a physically demanding job responsible for overexertion injuries in mining. This experiment studied rib scaling from an elevated bucket to examine force generation capabilities and electromyographic responses to a prying subtask.
-
3/1/2005 - Conference papersA package of bench design programs is being publicly released by the National Institute for Occupational Safety and Health (NIOSH). These programs are designed to provide a probabilistic estimate of the likelihood that various widths of catch bench will...
-
2/1/2005 - Conference papersOne focus of ground control research at NIOSH is to incorporate data on weak rock masses into existing design relationships, with an emphasis on updating the span design curve for manned entries and the overbreak curve for longhole entries. Both curves ...
