Numerical Simulation on flow fields for Coupling Gas and Coal Spontaneous Combustion in Gas Anomaly Area in coalmine

Published: 20 January 2017 Publication History

Abstract

In order to study the coupled disaster risk of regional spatial distribution of flow gas and coal spontaneous combustion in gas abnormal area, the model of coupling goaf gas and coal spontaneous combustion was established. Under the conditions of room temperature without oxygen consumption, different intensity of gas emission, different ventilation, and the concentration field of CH4 and O2 in goaf were simulated. The results indicated that as the increase of gas emissions, gas replacement and coal-oxygen consumption can reduce the oxygen concentration in deep of goaf. The range of oxidation zone of coal spontaneous combustion is decreased by numerous amount of gas emission from goaf. It provides a theoretical basis for obtaining the spatial distribution of dangerous zone for coupling disaster of gas and coal spontaneous combustion in the gas anomaly area in coalmine.
