摘　　要：为明确刘楼矿井下无轨运输车辆发生火灾时的避灾路线,根据矿井火灾烟气扩散规律,采用数值模拟的方法,利用FDS火灾模拟软件获取运输巷柴油设备起火时的CO生成规律与数据,将其代入Ventsim通风系统三维仿真软件,开展起火10 min内及主扇风机反转后的CO扩散时间与空间多维度的仿真计算。研究结果表明:反风后6~10 min,约70 ppm的CO将进入2#主井石门区域,对2#主井区域人员撤离造成不利影响;增加-200 m 1#主井~2#主井联巷避灾风门后,反风试验实测结果达到预期效果。根据CO的时空演化仿真及现场实践,为矿山避灾路线的制定提出调整建议。研究结果可为多中段、多井筒生产的地下矿山优化通风系统、提高避灾能力提供参考。In order to clarify the disaster avoidance route during the fire of underground trackless transport vehicle in Liulou Mine,according to the law of smoke diffusion in the mine fire,the numerical simulation method was adopted,and the CO generation law and data of the diesel equipment fire in the transport lane were obtained by using FDS fire simulation software,which was substituted into the three-dimensional simulation software of Ventsim ventilation system.The simulation calculation on multi-dimensional CO diffusion time and space within 10 min of fire and after main fan inversion was carried out.The results show that about 70 ppm CO will enter the crosscut area of#2 main shaft within 6~10 min after the reverse wind,which will adversely affect the evacuation of personnel in#2 main shaft area.After adding the disaster avoidance ventilation door of connection lane between-200 m 1#and 2#main shaft,the measured results of reverse wind experiment reach the expected effect.Based on the spatio-temporal evolution simulation of CO and field practice,the adjustment suggestions are put forward for the formulation of disaster avoidance routes in mines.The research results can provide reference for optimizing ventilation system and improving disaster avoidance ability of underground mines with multi-level and multi-shaft production.
