2/1/2010 - Conference papersThe goal of this study was to determine the potential saving in workers' compensation (WC) premiums that could be achieved due to a reduction in rock fall injuries after roof screening.
-
10/1/2009 - Conference papersThis report describes a new seal testing program that will provide essential validation data for mine seal analysis and design methods.
-
2/1/2009 - Conference papersThis paper presents the results to date of a NIOSH investigation into the possible causes that would account for the observed higher trends in CWP disease progression through review, data analysis, and in-mine surveying.
-
5/1/2004 - Conference papersA case study is presented that relates statistical descriptions of joint sets to the distribution of local wedge failures along the crest of a catch bench at the Yellowstone Talc Mine.
-
8/1/2001 - Conference papersA statistical study of roof bolt performance was conducted in 37 U.S. mines. Analysis of the results led to guidelines for making preliminary estimates for bolt length, capacity, and pattern to improve roof stability in difficult conditions.
-
7/1/2001 - Conference papersIn Utah, 3-D, full waveform, autonomous microseismic arrays were placed underground and on the surface of a longwall coal mine with overburden exceeding 750 m. Overall 13,000 seismic events, including a magnitude 4.2 event, were detected and located.
-
7/1/2008 - Conference papersThis paper explores the relationships between deep-seated and shallow in situ stresses in several of the world’s coalfields, using a data base of more than 350 stress measurements from underground coal mines.
-
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.
-
8/1/2005 - Conference papersThis paper summarises the results of a research project whose goal was to provide the Australian coal industry with a rib support design methodology and software tool that could be utilised by suitably qualified colliery staff.
-
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.
