Numerical Simulation of Dividing Gob Spontaneous Combustion "Three Zones" by Double Index Method

摘要: 准确快速的划分采空区自燃"三带"可以为煤自燃防治提供重要参考依据,通过建立针对性的采空区流场数学物理模型和对"三带"的划分指标进行分析,运用双指标结合数值模拟的方法快速的划分采空区自燃"三带"。通过与现场实测数据的对比验证,数据结果吻合较好,可以在工作面推进前期就准确地划分出采空区自燃"三带"的分布。

Abstract: Fast and accurate division of gob spontaneous combustion "three zones" can provide an important reference for prevention and treatment of coal spontaneous combustion.Through the establishment of corresponding mathematical-physical model of gob flow field and the index analysis of dividing "three zones",gob spontaneous combustion "three zones" can be divided fast by using numerical simulation combining with double indexes method.By comparison validation with measured data,data results were in good agreement and the distribution of the gob spontaneous "three zones" can be divided accurately in earlier stage of working face forward.
