摘　　要：以示范矿井采空区监测的温度数据为实验基础,以国内外矿井通风理论、气体流动理论和传热学为理论基础,利用Fluent软件对采空区内温度场进行正逆双向模拟,2次模拟相互比较和印证,进而确定采空区隐蔽火源位置并分析其探测误差,建立基于正逆双向模拟的探测采空区隐蔽火源的模型。In this article, taking the temperature data measured in demonstration mine gob as experimental basis, taking domesuc mine ventilation theory, the gas flow and heat transfer theory as the theoretical basis, we used Fluent software to carry on forward and inverse temperature field bidirectional analog, two simulations results were compared with each other and confirmed, which determined the source of fire gob hidden location and analyze its error detection, the model was established based on gob hidden fire source detection and inverse bidirectional analog goaf model.
