2/1/2003 - Conference papersThis paper briefly discusses the current status and research activities aimed at protecting miners from of some miner health-related issues, including coal and silica dust, diesel, asbestos, noise, lead etc.
-
2/1/2003 - Conference papersThis paper reports on an extensive series of short-encapsulation pull tests that were conducted in the NIOSH Mine Safety Research Laboratory and operating mines in WV and PA.

Injury data show a dramatic reduction in roof skin injuries when screening is used. Five case studies in which roof screen was used are presented along with the costs of materials, impact on bolting advance rates, and potential ergonomic risks.
-
2/1/2003 - Conference papersReports on NIOSH full-scale experiments to evaluate the explosion-resistant characteristics of several new seal designs for rapid deployment during mine emergencies.
-
2/1/2003 - Conference papersReport on NIOSH studies using a 12-foot diameter sphere to identify key factors that may enhance the levels of CO associated with the detonation of several commercial trenching explosives.
-
2/1/2003 - Conference papersIn this paper, existing ore pass design criteria rules-of-thumb using current particle flow equations are reviewed and a comparison of two computer modeling programs, Working Model (WM 2-D) and PFC2d, to simulate rock flow are investigated.
-
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.

1/1/2003 - Conference papersComputer human modeling was used to examine machine appendage speed. The objective was to determine the impact of roof bolter machine appendage speed on the likelihood of the operator coming in contact with the appendage.
-
1/1/2003 - Conference papersDescribes the flammability tests conducted on 15 to 20 different noise abatement materials of various chemical compositions and thickness.
-
11/1/2002 - Conference papersThis study of the Chestnut Ridge Anticline found that high levels of horizontal stress are to be expected and that local geologic and topographic structures can alter the magnitude and possibly the orientation of the horizontal stress field.
