摘　　要：以玉石洼铁矿22#采场为研究背景,依据气体运动及求解理论,运用计算流体力学FLUENT模型对22#采场的优化方案进行效果仿真及反风模拟,并将模拟风量与设计风量、正常通风与反风情况进行对比,分析各测点断面风流速度和风量,掌握该反风方式的影响区域及井下各巷道反风时的通风状况、风流方向、风量大小及稳定性。模拟结果与设计结果基本吻合,在反风条件下,各主要回风道的进风量基本达到正常运转时风量的60%,并且根据现场情况,可以在10 min内实现主运输巷道内风向反转。研究表明,通风改造方案确实可行有效,通风线路、方向和风量能够满足设计要求,同时风机反转,反风效果亦能达到要求。Taking 22# stope as the research background,and on the basis of the gas movement and the solution theory,the computational fluid mechanics FLUENT model is used to make an effect simulation and reverse air simulation on the optimal scheme of 22# stope.Then,according to the contrasts of the simulation air volume with the designed air volume,the common air ventilation,and the reverse air volume,the air speed and volume at the section of each survey point are analyzed with the purpose of grasping the influence area and the ventilation condition,air direction,air volume and its stability in the reversed air situation.The simulation result and the design result are consistent with each other.In reverses air conditions,the air volume at each main return air-way can reach 60% of the air volume at the normal situation of the fan.And according to the actual condition,the air backing at the main return air-way can be realized within 10 min.The research indicated that this ventilating proposal is feasible and effective,and the ventilating circuit,direction and air volume can meet the design requirements.Meanwhile,when the fan is reversed,the air backing effect can also meet the requirements.
