摘　　要：为便于矿井通风管理,对四老沟矿通风阻力进行测定。结果表明,矿井通风阻力为1163.0 Pa,通风阻力分布较为合理,矿井通风系统等积孔为8.89 m^(2),现阶段属于容易通风矿井。但由于矿井通风系统中有5个进风井、1个回风井,应加强巷道维护,合理设置通风设施,合理配风,平衡各通风线路通风阻力,确保通风系合理运行、各通风线路稳定。In order to facilitate mine ventilation management,the ventilation resistance of Silaogou Mine is measured,whose results show that the ventilation resistance of the mine is 1163.0 Pa,the distribution of ventilation resistance is reasonable,and the isocratic hole of the mine ventilation system is 8.89 m^(2),which is easy to ventilate at this stage.However,since there are 5 air intake shafts and 1 return air shaft in the mine ventilation system,roadway maintenance should be strengthened,ventilation facilities should be set up reasonably,air distribution should be reasonable,and the ventilation resistance of each ventilation line should be balanced to ensure reasonable operation of the ventilation system and stable ventilation lines.
