摘要
根据近距离煤层采空区渗流及扩散数学模型,利用东荣二矿近距离煤层采空区的特征,对该近距离煤层采空区作出了相应的假设,并利用近距离煤层工作面的现场观测数据,进行数据拟合,得出了相应的函数方程,建立了近距离煤层采空区自然发火预测模型.利用CFD软件FLUENT6.0进行解算,得出了近距离煤层采空区氧浓度变化值、速度变化值、压力变化值等结果,与实际相符.图2,参8.
According to mathematical model of percolation and diffuse of feature of goat" of close distance coal seams in the coalmine of 2# DONGRONG, close distance coal seams, making use of observation data of scene in working goaf of close distance coal seams, using making corresponding assumes of goaf of face of close distance coal seams for data fitting, reaching corresponding equations, setting up forecast model of spontaneous combustion in goaf of close distance coal seams. Use of the FLUENT 6.0 of CFD software for resolving, reach on the value of variation of 02, value of variation of velocity, and value of variation of pressure, and accord with the fact of coalmine. 2figs., 8refs.
