FLUENT数值模拟在确定采空区自燃"三带"中的应用
Application of FLUENT numerical simulation in determining goaf spontaneous combustion"three zones"
摘要
Abstract
In order to determine the distribution of the"three zones"of spontaneous combustion in the goaf of fully mecha-nized mining face,the FLUENT numerical simulation method is used to study the"three zones"of spontaneous combustion in the goaf of Laoshidan Coal Mine.By building a model for the goaf of the working face,the O-ring parameters of mining fracture is determined,the seepage control equation and the momentum equation of the porous media in the goaf are estab-lished,and the index dividing the"three zones"of spontaneous combustion is determined as the size of the air leakage ve-locity in the goaf.FLUENT numerical simulation is carried out and the wind velocity distribution diagram is drawn.Accord-ing to the distribution of wind speed,the"three zones"range of spontaneous combustion in goaf is figured out to provide scientific basis for fire prevention.关键词
