2/1/2009 - Conference papersThe load-deformation characteristics and the load capacity of welded wire screen (roof screen) used to control ground fall were evaluated in the laboratory in a specially built test frame.
-
12/1/2008 - Peer reviewed journal articlesThis report examines the development of modern pumpable roof support technology and provides a full description of the performance capabilities of each of the support products now on the market.
-
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.
-
8/1/2000 - 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).
-
5/1/1997 - Technology NewsThe new permissible-type, intrinsically safe design modules described here represent an engineering intervention strategy toward improving miners' ability to recognize and avoid the hazardous zone of unsupported mine roof.

9/22/2015 - Catalogs and indexes, Research areasNIOSH Mining topic page on rock falls.
-
8/1/2005 - Conference papersNIOSH continues to investigate the behavior of fully grouted roof bolts in the weak roof rock of Pittsburgh's Safety Research Coal Mine. This paper describes the results of three roof bolt studies.
-
8/1/2003 - Conference papersThis paper presents information that shows that short-encapsulation pull tests can provide the information necessary to improve ground control in variable roof conditions.
-
8/1/2002 - Conference papersThe story of how roof bolting was implemented by the mining industry, but took so long to live up to its promise, is a fascinating example of the interaction between economics, technology, regulation, and science. It still has important lessons for today.
-
3/1/1999 - Conference papersTo help mitigate the potential for falls-of-ground injuries to underground stone miners, NIOSH developed the Roof Monitoring Safety System (RMSS) to aid in monitoring dangerous levels of roof beam deflection.
