摘　　要：针对平顶山中祥永泰煤业有限公司的实际生产情况,采用基点测压计法对矿井通风系统进行通风阻力测定,矿井进风段、用风段、回风段通风阻力分别为54.90 Pa、290.92 Pa和305.09 Pa,回风段阻力占比较大,但阻力分布状况基本合理,测定结果表明了矿井回风段需要进一步优化,同时为矿井通风设计和管理提供了数据基础,确保了矿井的安全生产。According to the actual production situation of Pingdingshan Zhongxiang Yongtai Coal Industry Co.,Ltd.,the ventilation resistance of the mine ventilation system is measured by the base point piezometer method.The ventilation resistance of the air inlet section,the air use section and the air return section are 54.90 Pa,290.92 Pa and 305.09 Pa respectively,and the resistance of the air return section accounts for a large proportion.But the resistance distribution is basically reasonable.The measurement results show that the return air section of the mine needs to be further optimized.At the same time,it provides the data basis for the design and management of mine ventilation,and ensures the safety production of the mine.
