7/1/2010 - Conference papersThis paper makes use of numerical models to examine the interaction between typical pillar systems and the surrounding rock mass for weak and strong geological conditions at various spans and depths of cover.
-
8/1/2003 - Conference papersThe advance-and-relieve method benefits from lateral destressing. Numerical modeling proved useful in studying the basic mechanics of lateral relief while investigating the sensitivity of results to different parameters using controlled experiments.
-
2/1/2010 - Conference papersNIOSH is investigating the use of shotcrete in weak rock mass mines with the objective of reducing fatalities and injuries resulting from rock fall accidents.
-
11/1/2009 - Conference papersThis paper demonstrates the applications of coal bed reservoir engineering and modeling techniques for optimizing and controlling methane emissions in longwall and continuous miner sections.
-
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 papersThis paper reviews design methodology in the placement and analysis of sill mats with reference to site observation coupled with on going numerical and analytically derived solutions.
-
8/1/2006 - Conference papersDescribes the procedures and thought processes used by coal mine geologists when determining various mineability and reserve extraction feasibility issues. The paper also address underground geologic hazard mapping and prediction techniques.
-
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 ...

8/1/2004 - Conference papersAverage UCS may differ between coreholes but not be statistically significant, and widely spaced coreholes may be able to identify valid spatial trends in rock strength. The paper describes NIOSH's extensive investigation into these issues.
-
2/1/2003 - Conference papersThis paper discusses roof monitoring, roof movement, the large roof fall, propagation of roof failures, and the recent support measures to stabilize the escapeway over a portion of the older limestone mine workings at the NIOSH Lake Lynn Laboratory.
