摘　　要：矿井巷道火灾发生时,以三维矿井仿真平台为基础,构建矿井通风三维模型。结合火灾风流温度、浓度、火风压3种模型,对火灾风流的动态蔓延过程及原理进行研究。通过建立调控物理模型,利用Pyrosim软件对调控方案进行模拟,并利用小尺寸通风系统开展实验,验证调控方案的可行性。结合内蒙古巴彦高勒煤矿三维通风系统模型,模拟火灾发生在不同位置时的烟气流动情况,并以主运输巷道烟气蔓延为例,对其烟流路径进行有效控制,使火灾烟气以最短时间排出矿井,尽量减少火灾带来的危害。When a mine roadway fire occurs,a three-dimensional model of mine ventilation was constructed based on the 3D mine simulation platform.Combined with the three models of fire wind flow temperature,concentration and fire wind pressure,the dynamic spread process and principle of fire wind flow were studied.By establishing the physical model of regulation,the control scheme was simulated by Pyrosim software,and the experiment was carried out by using the small-size ventilation system to verify the feasibility of the control scheme.Combined with the three-dimensional ventilation system model of Bayangaole Coal Mine in Inner Mongolia,the flue gas flow when the fire occurs in different positions was simulated,and the smoke flow path was effectively controlled by taking the flue gas spread in the main transportation roadway as an example,so that the fire flue gas can be discharged from the mine in the shortest time to minimize the harm caused by the fire.
