摘　　要：随着煤矿开采活动的进行,高瓦斯危险区域处理问题越来越受到煤矿企业的重视。文章在分析采空区孔隙率、漏风场的基础上,建立了采空区气体流速和氧浓度数学模型,通过流体动力学软件模拟,划分出了王庄煤矿2506综采工作面采空区瓦斯自燃三带。With the mining activity, the risk treatment problems in the high gas areas get the attention of coal mine enterprises. In the paper, based on analyzing the goaf porosity, air leakage field foundation, the fluid dynamics mathematical model of the goaf gas flow velocity and oxygen concentration is established. Through simulation softwares, three belts of goaf spontaneous combustion at 2506 fully mechanized face in Wangzhuang Coal Mine are divided.
