6/1/2010 - Conference papersIn this NIOSH study, a computational fluid dynamics (CFD) model developed in previous work is used to model the effect of seal leakage on spontaneous heating of coal in longwall gob behind the seal.
-
2/1/2010 - Conference papersThis paper describes lab experiments to examine the effect of spray type, pressure, machine body blocking sprays, and scrubber airflow on dust and gas levels while using a 12.2 m (40 ft) exhaust ventilation curtain setback from the face.
-
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.
-
6/1/2010 - Conference papersThis study's goal was to validate the use of Ventgraph in a deep M/NM mine fire and illustrate its use as a valuable tool in mine ventilation, fire, and evacuation planning.
-
6/1/2009 - Conference papersThis paper aims to examine the effects of porosity and permeability changes of the coal seam on methane emissions in an underground continuous miner section.
-
2/1/2009 - Conference papersThis paper describes an inflatable temporary mine sealing technology and presents the results of NIOSH tests on the device.
-
2/1/2009 - Conference papersThis paper discusses the current ventilation practices regarding the use of belt air during gateroad development and longwall panel extraction.
-
2/1/2009 - Conference papersThis paper discusses some ways to find extra usable air when there is no extra ventilation capacity.
-
6/1/2008 - Conference papersThis paper compares the transverse load capabilities of several block materials and wall dimensions commonly used in stopping constructions based upon simulated three-hinge, rigid-arch loading tests of half-wall constructions.
-
6/1/2008 - Conference papersThis paper summarizes the modeling efforts conducted by NIOSH in the U.S. and CSIRO in Australia to address various gas management issues encountered in longwall mines using the application of computational fluid dynamics (CFD) and numerical reservoir m...
