综放工作面采空区自燃“三带”数值模拟研究

Numerical Simulation of Spontaneous Combustion "Three Zones" in Goaf of Fully Mechanical Working Face

基于现有采空区自燃"三带"的研究水平和本矿的实际情况,利用COMSOL模拟软件,模拟豹子沟煤矿首采综放工作面不同风量时采空区自燃"三带"的分布变化情况,并与现场实测数据进行比较,确定了该工作面采空区自燃"三带"范围,为预防自然发火提供依据。

Based on research level and the actual situation of the existing goaf spontaneous combustion ＂three zones＂,using software COMSOL simulation,simulating the distribution changes of goaf spontaneous combustion ＂three zones＂ of Baozigou Coal Mine first to gather the different air volume of full-mechanized caving mining face,and in comparison with field measured data,we determines the scope of the working face goaf spontaneous combustion ＂three zones＂,which provide a basis for the prevention of natural fire.
