7/1/2010 - Conference papersThe paper provides a basic set of input data and a modeling approach that can be used for numerical modeling investigations of various coal mine designs using the FLAC3D software package.
-
11/1/2008 - Conference papersThis article discusses how narrative-based training has evolved and is likely to continue changing in the future using the Underground Coal Mine Map Reading Training (UCMMRT) developed by NIOSH.
-
6/1/2008 - Conference papersThe results of field tests to understand how ventilation and gob characteristics affect the spontaneous heating process causing spontaneous combustion fires in longwall or worked-out gob areas are presented.
-
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.
-
8/1/2004 - Conference papersThis paper focuses on a computer simulation used to model roof behavior and rock bolt interaction in a collaborative study of ground behavior, reinforcement performance, and stress redistribution in a coal mine entry under severe horizontal stress.
-
6/1/2004 - Conference papersThe point estimation method for the probability of sliding is efficient and expedites slope stability simulation routines in NIOSH software to stochastically describe rock slope behavior and assist engineers in catch bench design for large slopes.
-
5/1/2004 - Conference papersA case study is presented that relates statistical descriptions of joint sets to the distribution of local wedge failures along the crest of a catch bench at the Yellowstone Talc Mine.
-
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.
-
7/1/2001 - Conference papersOutlines the concepts used to correlate rock failure with microseismic events and presents examples of microseismic monitoring together with associated computer modeling of the rock failure from several mine sites.
