5/1/2007 - Conference papersThis paper discusses the sources used in developing the CMRR, describes the CMRR data collection and calculation procedures, and briefly presents a number of practical mining applications in which the CMRR has played a prominent role.
-
6/1/2006 - Conference papersNIOSH conducted a study with the goal of characterizing methane emissions from increasing face lengths in the Pittsburgh Coalbed and providing a method of predicting emissions increases from longer faces and of planning for more methane control.
-
6/1/2006 - Conference papersNIOSH conducted a longwall methane emission and mining time study at a Pittsburgh Coalbed mine to predict emissions from a longer face, and developed and applied mathematical formulas and constants to characterize four emission contributors.
-
3/1/2006 - Conference papersA computational fluid dynamics (CFD) program was applied to fire spread along combustibles in a ventilated mine entry. The rate of flame spread was evaluated for the ribs and roof of a coal mine entry, timber sets, and a conveyor belt.
-
8/1/2003 - Conference papersThis paper describes a study where the variations of the magnitude of the horizon stresses in sedimentary deposits in the eastern and Midwestern U.S. are examined with respect to two factors, the elastic modulus of the rock and the site depth.
-
11/1/2013 - Conference papersA NIOSH study investigating the potential for lithium-ion battery thermal runaway from an internal short circuit in equipment approved as permissible for use in underground coal mines.
-
9/1/2010 - Conference papersThis study assessed the difference between free cadence walking versus stoopwalking (under a 1.2-m ceiling), four-point crawling (hands and knees), and two-point crawling (knees only), both with and without kneepads.
-
6/1/2010 - Conference papersThis study examined the potential for coal mine roof bolter dust to be a source of a worker's exposure to respirable quartz.
-
2/1/2010 - Conference papersNIOSH is investigating the use of shotcrete in weak rock mass mines with the objective of reducing fatalities and injuries resulting from rock fall accidents.
-
1/1/2010 - Conference papersThis paper discusses several milestone events that show the progress of methane control research in underground coal mines.
