基于特厚煤层瓦斯抽采与煤自燃双重耦合影响,确定综放工作面的临界瓦斯抽放量.根据束管监测系统现场实测及利用Fluent软件数值模拟,得出煤自燃防治条件下的综放工作面临界风量为1100m^3/min,综合瓦斯抽采与煤自燃防治耦合影响下的临界瓦斯抽放量为180m^3/min.

英文摘要：

Based on the double coupling influence of gas drainage and coal spontaneous combustion in the extra-thick coal seam, the critical gas drainage volume in the fully mechanized caving face was determined. According to the site measurement by the bundle tube monitoring system and the numerical simulation with Fluent software, it was obtained that the critical air quantity in the fully mechanized caving face was 1 100 m3/min under the control conditions of coal spontaneous combustion and the critical gas drainage volume in the fully mechanized caving face under the coupling influence of the comprehensive gas drainage and the prevention and control of coal spontaneous combustion was 180 m3/min.
