摘　　要：矿山生产中,通风系统扮演着关键角色,直接影响工作面环境的安全性。以银山铜矿为背景,针对-358,-458 m中段的通风系统,通过现场调查和测定,并对测定数据进行统计与分析。结果发现,该铜矿存在-358 m铅锌老系统风机通风效果不明显,-458 m中段采区通风困难,通风构筑物不完善等问题。为此,建立Ventsim三维仿真系统模型,制定通风系统优化方案,完善通风构筑物,并对实施方案优化效果进行模拟。工程实践结果表明,风速合格率为从原来的35.6%提高到73.7%,作业面工作环境得到明显改善。该优化方案有效解决了矿山面临的通风与环境问题,为类似矿山提供了经验。In mine production,the safety of ventilation system plays a key role,which directly af⁃ fects the safety of working environment. Based on the background of Yinshan Copper Mine,the ventilation system in the middle section of -358 and -458 m is investigated and measured on site,and the measured data are analyzed statistically. The results show that the ventilation effect of the -358 m lead-zinc old sys⁃ tem fan is not obvious,the ventilation is difficult in the -458 m middle mining area,and the ventilation structure is not perfect. Therefore,the Ventsim 3D simulation system model was adopted to formulate the ventilation system optimization scheme,improve the ventilation structure,and simulate the optimization effect of the implementation scheme. The results of engineering practice show that the qualified rate of wind speed is increased from 35.6% to 73.7%,and the working environment of the operation surface is ob⁃ viously improved. The optimization scheme effectively solves the ventilation and environmental problems faced by the mine,and provides experience for similar mines.
