摘要
在分析煤火控制体范围及其介质属性特征的基础上,结合煤层开采上覆岩层移动规律,确定了煤火控制体内不同裂隙区域空间范围及其透气率的计算方法。提出了单元煤田火区烟气流场模型等效透气率Ke的计算方法。在此基础上,提出了单元火区单位时间耗氧量的计算方法。
Based on analyzing the characteristics of coal fire zone as well as its porous materials,and together with the application of the rocks control theory,proposed a method to determine the different fissures/cracks divisions as well as its permeability with coal fire zone.With the analysis of element fire-zone＇s air/smoke flow model,put forward a method to determine the equivalent permeability Ke for element coal fire zone and also proposed its verification and modification.Finally,a method of calculating oxygen consumption was also proposed as an example of application.
