6/1/2006 - Conference papersNIOSH research suggest that by incorporating ventilation planning into the mine planning process, using propeller fans, developing new stopping materials and construction methods, and using long pillars to eliminate crosscuts where possible, the ventila...

3/27/2006 - Conference papersA methodology to assess the risk for a roof fall is proposed in a preliminary fashion based on engineering judgment acquired from extensive underground stone mine experience and examination of related literature.
-
3/1/2006 - Conference papersNIOSH is conducting full-scale tests at its Lake Lynn Experimental Mine to evaluate/improve remote mine seal construction technology, focusing on technology to completely close the mine opening, & reporting results from use of grout-based materials.

1/1/2006 - Peer reviewed journal articlesThe Thermo-MIE personal DataRAM dust monitor (pDR) is a light-scattering instrument approved for use in gassy underground mines by the U.S. Mine Safety and Health Administration (MSHA). However, the use of light-scattering monitors has been inhibited by...
-
2/1/2005 - Conference papersOne focus of ground control research at NIOSH is to incorporate data on weak rock masses into existing design relationships, with an emphasis on updating the span design curve for manned entries and the overbreak curve for longhole entries. Both curves ...

1/1/2005 - Peer reviewed journal articlesThis publication details a series of explosive detonation experiments conducted in NIOSH's Bruceton and Lake Lynn Experimental Mines to evaluate low-level (<6 psig) detonation wave propagation behavior in single- and multiple-entry configurations.
-
6/1/2004 - Conference papersNIOSH researchers have identified a pattern of fracture zone development as an explanation for fracture formation around rectangular openings in underground mines. Two computer modeling codes were used to model different aspects of this pattern.
-
5/1/2004 - Conference papersResearchers are investigating the causes and mechanisms of roof failure in underground mines with the goal that better understanding these issues will lead to better layout and support designs to help prevent fall-of-ground accidents and fatalities.
-
5/1/2004 - Conference papersThis study describes how response times of machine-mounted methane monitors were measured by placing the methane sensor heads in a specially designed box where they were exposed to an atmosphere containing a constant concentration of methane.
-
5/1/2004 - Conference papersDescribes a computer program developed by NIOSH for estimating the air quantity needed to dilute diesel particulate matter in underground large opening mines.
