摘　　要：针对某矿井下溜破系统排尘风机工作效率低的问题,利用FLUENT软件,对-270m水平17线回风联巷风机所排出风流的流动规律和-370m中段距17线回风天井井口较远的排尘风机的运行进行了研究,结果表明:-370m中段溜破系统长距离排尘巷道内的风流大面积回流,且又重新进入风机的入风口,最终导致粉尘大量堆积在-370m中段溜破系统长距离排尘巷道内无法排出。根据已发现的问题,给出了回风机站建设的建议。To address the low efficiency of dust-exhausting fans in ore pass-breakage system in an underground mine, FLUENT software is used to study the law of air flow exhausted by the fan in the air-return linkage tunnel in 17 line at level --270 m, and the running of the dust-exhausting fan far from the return air o- pening in 17 line at level --370 m, the results show that the air flow will flow back massively in the long distance dust exhaust tunnel of the ore pass-breakage system at level --370 m,backflow enters into the inlet of the fan again, the end result is that dust will be accumulated in the long distance dust exhaust tunnel of the ore pass-breakage system at level --370 m, and is unable to be discharged. According to the detected problem, some strate- gies in the fan station construction are provided in response to the discovered problems.
