摘　　要：为了采取合理的注氮方案降低采空区自燃危险性,利用FLUENT软件模拟了注氮前后采空区自燃带范围的改变情况,并分析了注氮位置和注氮量对采空区氧化带位置分布的影响,从中拟合出最佳的注氮参数。依据理论研究结果,取得了理想的现场注氮效果,研究结论可为类似采空区防火工作提供参考。In order to adopt reasonable nitrogen injection pattern to decrease the spontaneous combustion danger in goaf, the FLUENT software was used to study the change of goaf oxidation region status before and after nitrogen injection, and analyze the effect of nitrogen injection position and flux on oxidation region scope. Thus, the best suitable injection parameters can be gained by fitting. Site application shows that the nitrogen injection can obtain ideal fire prevention result. Hence, research conclusion can provide reference for fire prevention of work face with similar production conditions.
