6/1/2003 - Conference papersThe primary objective of the paper will be to discuss strata mechanics and ways in which the support and strata interaction can be evaluated to provide an optimized secondary support design, particularly standing support systems, for longwall tailgates.
-
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 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.

Roof screening has been found to be very effective in controlling the fall of small rocks from the immediate roof surface. Data is presented from two mines that show a dramatic reduction in roof skin injuries when screening is used.
-
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.

8/1/2002 - Conference papersNIOSH has been evaluating developments in sealant support systems for ground control. This paper reviews current technology in shotcrete and membrane development, evaluates a long-term study of sealant materials, and examines installation practices.
-
8/1/2002 - Conference papersSlope stability accidents are a leading cause of fatalities at U.S. surface mines. NIOSH is conducting research to reduce these fatalities. This paper presents some of the research and potential new technologies for slope monitoring and design.
-
8/1/2002 - Conference papersThis paper offers a close look at the complex structural environment of the Loyalhanna Limestone of southwestern Pennsylvania. Analyses were performed using gas well and core logs, outcrop examinations, underground observations, and mine maps.
-
7/1/2002 - Conference papersThe investigation reported here is an initial study of the stability of the first of the proposed chambers at the Homestake Mine in Lead, SD.
-
7/1/2002 - Conference papersA case study of a rock burst was conducted as part of a project to reduce rock burst hazards being undertaken by the Spokane Research Laboratory (SRL) of the National Institute for Occupational Safety and Health (NIOSH).
