8/1/2004 - Conference papersThis paper focuses on a computer simulation used to model roof behavior and rock bolt interaction in a collaborative study of ground behavior, reinforcement performance, and stress redistribution in a coal mine entry under severe horizontal stress.
-
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.
-
8/1/2003 - Conference papersThis paper describes a study where the variations of the magnitude of the horizon stresses in sedimentary deposits in the eastern and Midwestern U.S. are examined with respect to two factors, the elastic modulus of the rock and the site depth.
-
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.
-
8/1/2001 - Peer reviewed journal articlesThe CMRR quantifies defects in the rock mass and compiles a strength value used for engineering design. The CMRR has been applied to a number of ground stability problems. The CMRR procedure and some of these applications are described in this paper.
-
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).
-
1/1/2000 - Conference papersThis paper outlines the evolution of the RMSS and how it can be used in a comprehensive, proactive ground control safety program. A case history describes the RMSS being used to evaluate a mechanical impact sealing machine at a limestone mine.
