An Analysis of Reservoir Conditions and Responses in Longwall Panel Overburden During Mining and its Effect on Gob Gas Well Performance2/1/2012 - Peer reviewed journal articlesNIOSH conducted a cooperative research study to provide direct measurements of changing reservoir conditions in longwall panel overburden.
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.
3/1/2010 - Peer reviewed journal articlesIn this paper, Computational Fluid Dynamics modeling of the effect of longwall face advance on the spontaneous heating of coals in a two-panel gob area using a bleeder ventilation system is presented.
Modeling the Effect of Barometric Pressure Changes on Spontaneous Heating in Bleederless Longwall Panels3/1/2010 - Conference papersThe effect of inflow and outflow of gas on the potential spontaneous heating in the gob was investigated using the computational fluid dynamics (CFD) model.
11/1/2008 - Peer reviewed journal articlesA computational fluid dynamics (CFD) study was conducted to model effects of coal properties on the potential for spontaneous heating in longwall gob (mined-out) areas.
8/1/2008 - Peer reviewed journal articlesTo provide insights for the optimization of bleederless ventilation systems for U.S. underground coal mines, a computational fluid dynamics study was conducted to model spontaneous heating in longwall gob areas using a bleederless ventilation system.
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.
12/1/2007 - Peer reviewed journal articlesComputational Fluid Dynamics simulations were conducted to investigate the spontaneous heating of coals in longwall gob areas with different apparent activation energies and reaction surface areas. The results are reported in this paper.
3/1/2018 - Peer reviewed journal articlesAn article about a study to analyze production performances of gas gov ventholes drilled over a longwall panel as a methane control measure.
7/18/2016 - Contracts and cooperative agreementsA capacity-building contract to expand on previous and existing work with computational fluid dynamics (CFD) modeling using the FLUENT code to develop a modeling and predictive tool for mine ventilation.
