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.
-
10/1/2000 - Information CircularsThe proceedings provide information on several new technologies including guidelines for roof bolt length, pattern, and capacity; a new design method for longwall tailgate supports; and a technique for measuring loads developed within cable bolts.
-
12/1/2019 - Peer reviewed journal articlesThis paper outlines the design parameters for a shield dust simulator.
-
2/2/2018 - Peer reviewed journal articlesAn article examining the ability of foam to maintain roof coverage in a simulated longwall mining environment.
-
2/22/2017 - Research projectsA project to identify and develop improved respirable dust controls for coal mines and facilitate their implementation to reduce the dust exposures of mine workers.
-
4/1/2010 - Peer reviewed journal articlesThis paper investigates the influence of air velocity and shield advance rates on respirable dust levels. Also discussed are engineering controls currently used to reduce shield dust and alternative controls being investigated by NIOSH.
-
1/1/2010 - Conference papersThis paper describes the impact of ground control research by the Bureau of Mines and NIOSH on the safety of underground coal miners.
-
7/1/2007 - Conference papersA cooperative study was conducted to evaluate the effectiveness of (partially) pre-driven longwall recovery rooms supported with pumpable roof supports.
-
7/1/2007 - Conference papersThis paper addresses both the safety and the operational issues associated with mobile roof support (MRS) usage during shield recovery. It also discusses new developments, including the use of the inherently safer battery powered MRS'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.
