7/1/2007 - Conference papersA unique circumstance created by monitoring a pre-driven longwall recovery room permitted measuring the stresses of a coal pillar throughout its entire life cycle in less than a week. The complete transformation took place in less than 12 hours.
-
7/1/2007 - Conference papersThis paper presents the results of a study of roof conditions in 34 limestone mines in the Eastern and Midwestern U.S.
-
6/1/2007 - Conference papersThere are fundamental aspects of support design and ground control that we still do not understand or recognize when designing a support system. These issues are evaluated and a different approach to support design is proposed.
-
5/1/2007 - Conference papersA survey of roof and pillar conditions in limestone mines has revealed that bench mining of the floor between pillars can cause instability in the pillars at the perimeter of the benched area. Numerical models were used to assess those effects.
-
4/1/2007 - Conference papersThis paper presents an overview of recent innovations in support technology for hard rock mining.
-
1/1/2007 - Conference papersAnalysis of Multiple Seam Stability (AMSS) is a computer program to help mine planners evaluate potential interactions and reduce the risk of ground failure. This paper details a NIOSH study of multiple seam interactions and the development of AMSS.
-
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.
-
8/1/2006 - Conference papersThis paper discusses progress in the science of coal pillar design over the past 25 years and some of the current research needs.
-
8/1/2006 - Conference papersThis paper explores the history of longwall shield design over the past 25 years. It also addresses questions such as whether two-legged designs are better than four-legged shields and whether setting pressures should be set as high as possible.
-
6/1/2006 - Conference papersThis paper presents the results of a study into the ground response around tailgate entries using numerical models. The potential exists to develop site-specific tailgate design curves by combining model results with field observations.
