3-D simulation of gases transport under condition of inert gas injection into goaf
TL;DR: In this paper, the authors modeled the coal goaf as a 3D porous medium based on stress distribution and simulated the variation of O2 distribution influenced by CO2 or N2 injection.

Numerical study on the evolution of methane explosion regions in the process of coal mine fire zone sealing
TL;DR: In this paper, the authors analyzed the change law of methane explosion limits under the influence of CO2 and CO by using a thermal balance methodology and obtained the distribution rules of methane, smoke and oxygen in the fire zone for different fire source locations.

Experimental and in-situ estimation on hydrogen and methane emission from spontaneous gasification in coal fire
TL;DR: In this article, the emission characteristics of hydrogen and methane in the thermochemical process of coal oxidation are investigated by both laboratory tests and on-site measurements Employing an adiabatic oxidation test, the releasing rules of index gases in limited space were estimated with programmed temperature rising up to 200°C Experimental results demonstrate that the releasing concentrations of methane and hydrogen preform an exponential trend with oxidation temperature.

Model and simulation analysis of fire development and gas flowing influenced by fire zone sealing in coal mine
TL;DR: In this paper, the authors investigated the distribution and evolutions of temperature and CH4 concentration fields during fire zone sealing and revealed the mechanism of sealing-induced gas explosion accidents, where the results showed that in the sealing process, the airflow into the fire zone gradually decreases and air begins to flow out through the air intake at the later stage.

Heat transfer and thermodynamic processes in coal-bearing strata under the spontaneous combustion condition
TL;DR: In this paper, a combined heat transfer model of conduction, convection, and radiation with finite reactions is developed for the porous coal and rocks, and the temperature distributions in the coal and roof strata at different times are simulated based on the single and two-stage kinetic models, respectively, and compared with field geophysical prospecting.
